MISSISSIPPI I. INTRODUCTI ON A. Operator Responsibilities The purpose of this plant is to safely and economically convert vinyl chloride monomer (VCM) into a useable form of poly vinyl chloride (PVC) This is accomplished by a batch process in which VCM, water, initiator and colloid solution are charged into the reactor and under carefully controlled conditions, PVC with the desired physical properties is produced. This chemical reaction, which changes VCM to PVC, is called polymerization. The operator helps fulfill the plant's purpose by making sure that quality production is obtained from his equipment without endangering his fellow workers or his equipment. The operator is able to attain his goals in safety, job performance and efficient operation through a training period and on the job experience and passing a written The operator fulfills his responsibilities by: 1. Demonstrating understanding of how his equipment functions. 2. Being able to explain what role each piece of equipment plays in the process. 3. Keeping a close and regular check on equipment. 4. Being able to demonstrate trouble shooting and corrective measures. 5. Keeping his area of responsibility safe and clean. 6. Keeping complete and accurate records.

A VAB.0001146643 Operating Manual D-745 PVC Reactors Page 3 I. INTRODUCTION (Cont.) B. Process Information Several types of resins are produced. Resin type is determined by a set of physical properties such as particle size and viscosity Each type of resin produced requires that a certain set of operating conditions be closely followed so that the desired resin properties are obtained. Minor changes in formulas or operating conditions can cause major differences in the physical properties of the resin. Some factors in determining resin properties are reaction temperature, which helps determine viscosity, colloid, which influences particle size, and the amount of recovered VCM charged, which also effects particle size, amount of short-stop which effects stability and amount of calcium stearate which effects drying and customer processing. The phases of reactor operation and a brief description of each follows: 1. Evacuation This step removed all air possible by steam ejectors. Too much air left in a reactor will alter particle size. Evacuation should re quire about five minutes. 2. Charge Water, Colloid and VCM are charged to the reactor simultaneously through a timed sequence system. The temperature of the reactor contents at the end of charging is determined by the charge water temperature. The reactor will be below run temperature at the end of the charge and jacket steam will be used to raise the temperature to the desired level. Charge should take about nine minutes for D-741, D-742, D-743, and D-744. D-745 will require about fifteen minutes to charge. VAB.0001146644 1-3 A Operating Manual D-7^5 PVC Reactors Page 4 I. INTRODUCTION (Cont.) B. Process Information (Cont.) 3. Initiator The initiator is manually loaded into the initiator injection pot and charged into the reactor after reactor charge is complete. 4. Polymerization This is the time from the initiator addition until most of the VCM has been converted to resin. The reaction generates heat continu ously as liquid VCM becomes PVC resin. Heat that is generated is removed by cooling water on the reactor jacket and condenser. Reaction time varies, but generally requires five to six hours for D-741, D-742, D-743, and D-744. D-745 will require about 4^ to five hours. 5. Recovery and Steam Stripping Recovery and steam stripping removes most of the unreacted VCM from the reactor via a compressor-vacuum pump system. Steam is added to the bottom of the reactor and rises through the PVC and water slurry to help remove unreacted VCM. Recovery and steam stripping takes about 60 minutes for D-741, D-742, D-743, and D-744 with D-745 taking about 90 minutes to recover and strip. 6. Dumping The PVC resin, after reaction is complete, is in a slurry form. The slurry is dumped to a sweco and dump tank and is pumped to blend tanks in the Dryer Room for drying. Dump requires about 25 minutes for D-741, D-742, D-743, and D-744 and 35 minutes for D-745. VAB.0001146645 1-3 A Operating Manual D-745 PVC Reactors Page 2 I. INTRODUCTION (CONTINUED) A.

Evacuation Before charging, the inerts present in the polymerization reactor are removed by evacuation. The interlock selector switch is placed on "evacuation" position. The main condenser valve is opened, the reactor evacuation valve is opened, the evacuation header valve, and the steam supply valves to the ejector system to be used are opened. Any condensate in the steam to the ejector is removed by a cyclone separator. The emergency cooling water supply valve to the reactor is then opened. When the reactor reaches 28.5 inches of mercury vacuum, as indicated by the pressure indicator in the control room and a manometer at the reactor, evacuation is complete. This portion of the cycle requires about five minutes. B. Charge 1. Precharge Preparation After evacuation, the reactor is ready to be charged. In pre paration for charge, adequate quantities of VCM, hot water, colliod solution, and initiator are made ready for the charge sequence. Prior to charge, fresh VCM is transferred from the VCM storage sphere to the fresh VCM storage tank. This transfer of VCM begins automatically when the VCM liquid level falls below a certain level. Whenthe high liquid level is regained, the transfer process shuts down automatically. Two 150 gpm VCM transfer pumps are used to transfer the VCM from the VCM storage sphere. m 'iriiniiMn iwwi im VAB.0001146648 1-3 A Operating Manual D-?U5 PVC Reactors Page 6 II. GENERAL PROCESS DESCRIPTION (CONTINUED) B. Charge (Continued) Process water is automatically supplied to the hot water tank when the water level drops below a certain point. The water is filtered by the process water filter, and is heated in the hot water preheater, enroute to the hot water tank. The hot water tank temperature is maintained by the external steam coils on the hot water tank. The colloid solution, previously madeup, remains in the makeup tank until tested and approved. The colloid percent total solids must be 1.40 - 1.60. The colloid is then pumped from the makeup tank to the colloid charge tank After each reactor charge, colloid is transferred at 50 gpm from the storage tank to the colloid charge tank by the colloid circulation pump. When the makeup tank contains less than one charge, the full charge tank will contain sufficient colloid to charge seven reactors. The colloid charge tank can be emptied to less than one charge while the new colloid solution is being made up and analyzed. Immediately before the reactor is to be charged, the initiator injection system is following manner. First, the initiator injection pot, at the reactor to be charged, is drained to the sdwer. One gallon of water is manually added as indicated by the local flow totalizer. mi.... .. ............................

The initiator is then manually added to the initiator injection pot. The pot is then blocked in and pressurized with high pressure service water to at least 180 psig. The initiator injection system is now ready for the reactor charge. When the charge is complete. CAUTION: The initiator should never be left in the charge pot if the charge is aborted. It is to be dumped to the sewer and the pot flushed with water. 2. Reactor Charge After evacuation is completed, the interlock selector switch is moved to the "charge" position. If the following precharge con ditions are met, the charge sequence is ready to begin: a. Levels in the fresh VCM storage tank, the hot water tank, and the colloid charge tank are adequate for a complete reactor charge. b. There is sufficient pressure in the initiator injection pot and in the high pressure service water header. c. The charge meters are reset to the charge quantities. Steam is usually applied to the reactor jacket at the start of charge by manually opening the steam valve from the Control Room. A * -- ....... .dl> - :rr. . --ft' - **' l~l II I 11 i"l ' !'

Reactor Charge (Continued) This aids in heating the reaction mass to the desired temperature and immediately following The automatic sequence begins with the hot water charge. The pumped from the hot water tank, to the reactor pump quantity water has been charged, the colloid charge pumps and the second hot water charge pump start. The next step in the charge sequence begins with the fresh and recovered VCM char The fresh VCM Is pusqped to the reactor from the fresh VCM storage tank, by one of the two VCM charge pumps. The recov ed VCM is lumped from one of two recovered VCM storage tanks by the recovered VCM charge pump Into the suction of the VCM charge pump. The recovered VCM la filtered In the recovered VCM filter and the total VCM charge Is filtered enroute to the reactor by the VCM charge filter. Shortly after the beginning of the VCM charge, one of the hot water charge pumps shuts down until the VCM charge is com pleted and then restarts. This insures that there will be an adequate amount of water charge remaining to flush out the charge line except on D-745 where the VC line is separate. Both hot water charge pumps continue to run until charge is completed. VAB.0001146651 1-3 A Operating Manual D-T^5 PVC Reactors Page 9 II. GENERAL PROCESS DESCRIPTION (Cont.) B. Charge (Cont.) 2. Reactor Charge (Cont.) When the VCM, water and colloid charge is complete, the initiator is charged by opening the initiator charge valve from the reactor by the "A" operator. Loading the initiator and preparation of the initiator charge pot was discussed in the precharge preparation section. C. Polymerization After charge is completed, the reactor interlock selector switch is placed in the "polymerization" position, and the reactor temperature controller is placed on automatic. When the reaction mass reaches 3 n below desired set point temperature the steam is turned off. The reaction mass temperature is automatically controlled by varying the amount of cooling water that is passed through the top--mounted knockback condenser and the reactor jacket. The reaction mass is continually mixed and kept in suspension by the bottom-mounted single speed agitator. The agitator mechanical seals are lubricated and cooled by seal oil from an oil pressure unit. IXiring polymerization, mechanical seal purge water is injected into the reactor through the reactor cleaning nozzle and through the agitator mechanical seal. The water is added to keep the reactor ............... .............................. - nmtwm m* n IPRH VAB.0001146652 Operating Manual D--T-^+5 PVC Reactors Page 10 ft* II. GENERAL PROCESS DESCRIPTION (CONTINUED) C. Polymerization (Continued) cleaning nozzle and agitator mechanical seals clean. The purge water flow for each service is indicated with a rotameter and manually adjusted. 1-3 A The inerts present in the reactor during polymerization from initiator decomposition, suspending agent and water accumulate in the reactor condenser head space. These inerts are vented to the recovery system to prevent inert blanketing. i When the desired degree of polymerization is reached and the reactor pressure has dropped to the desired pressure, the reaction is stopped by manually adding a mixture of AMS and Naugard (the short stop solution) to the reactor. High pressure service water is used to pressure the short stop solution from the initiator injection charge pot into the reactor through the same piping as the initiator charge piping. The charge pot is then blocked in and refilled with the short stop solution which will be used at the middle of steam stripping. An emergency AMS kill pot, located at grade, is provided to pressure AMS into the reactor to kill the reaction in the event of a power failure or upon loss of agitation. The AMS will be injected into the reactor through nozzles in the reactor head, using push buttons on the control panel or by manually operated valves in the field.

Polymerization (Continued) The pots for D-741, D-742, D-743 and D-744 will contain 15-20 gallons of AMS. The material will be pressurized into the reactors using nitrogen. A nitric oxide (NO) short stop addition system is provided to inject NO into the reactors in the event of power failure, major VCM releases, fires, or other emergencies. The system is activated locally. NO is supplied from the emergency NO short stop bottles and is injected into the reactor through the same piping as the agitator mechanical seal purge water.

Recovery When reaction is completed, the interlock selector switch is moved to the "recovery and steam stripping" position. The following sequence then occurs. The recovery compresssor seal water systems, the water recirculation systems for the recovery knockout drums, and two of the three recovery compressors are manually started from the board. Cooling water to the recovered VCM condenser and the water recirculation cooler starts automatic cally with the compressors, and the hydroquinone injection system starts with the compressor seal water systems. The vapor from the reactor flows through a pressure control valve to + two resin knockout drums in series which cool the vapor and remove carryover resin. The pressure control valve prevents excessive carry-- over of resin from the reactor by limiting the pressure to the recovery system to about 35 psig. Each of the knockout drums have an l internal water spray system and a recirculation pump. Both knock out drums have on-off level control system which, on high liquid level, divert; the discharge of the water recurculation pumps to the water stripper. A water recirculation-cooler, (the function of which is explained in the steam stripping portion of the recovery system process description). VAB.0001146655 Operating Manual D-7^5 PVC Reactors Page 13 II. GENERAL PROCESS DESCRIPTION (Cont.) D. Recovery and Steam Stripping (Cont.) is provided and can be used in the water recirculation loop of either scrubbing stage. The VCM vapors from the knockout drums are compressed by the recovery compressors. The recovery compressors are constant volume liquid ring compressors with a water seal. The discharge streams from the compressors flow to two parallel seal water recirculation systems which operate as follows. Seal water is separated from the VCM vapors in the seal water separators, filtered by the seal water filters, cooled by the seal water coolers, and pumped back to the compressors by the seal water pumps. The flow of seal water to each compressor is controlled at 50 gpm. The seal water temperature is controlled just above the VCM condensation temp erature (95-105F). Automatic draining of the seal water separators to the water stripper is provided to maintain the correct water level. The VCM vapors from the seal water system are condensed in two recovered VCM condensers. The condensed VCM is collected in the re covered VCM collect tank which is on automatic on-off level control. VCM is transferred to the recovered VCM storage tanks by the recovered VCM transfer pump when there is high liquid level in the VCM collect tank. Inerts are bled from the collect tank to the incinerator. mmmmmm.rn VAB.0001146656 1-3 \ ye***,. t Operating Manual D-745 PVC Reactors Page 14 II. GENERAL PROCESS DESCRIPTION (CONTINUED) D. Recovery and Steam Stripping (Continued) 1. Recovery (Continued) When the reactor pressure drops to 8 psig, the two recovery vacuum pumps automatically start. The VCM flow from the recovery knockout drums and the seal water flow are both diverted to the vacuum pumps which discharge into the suction of the compressors. w 2. Steam Stripping In order to reduce residual VCM in the slurry, the slurry in the reactor is heated and stripped with steam. At the start of a normal recovery, steam addition to the reactor is manually started from the control room and the slurry mass is heated. When the temperature of the reactor has risen to the desired temperature, the steam stripping operation is completed. As recovery proceeds, less and less VCM is recovered from the reactor. To supply sufficient VCM vapor to the recovery vacuum pumps and compressors, a VCM backpressure system is used. This is done to prevent cavitation and overheating of the vacuum pumps and compressors. Before entering the recovery knockout drums, the steam and VCM from the reactor are combined with a bleed stream of VCM from the recovered VCM storage tanks. The amount of VCM bled into the recovery system is adjusted by the backpressure control valve such that a set supply pressure to the vacuum pumps is maintained.

Steam Stripping (Continued) The majority of the steam la condensed In the first knockout drum described In the normal recovery process description. The first stage of the scrubbing system consists of a recovery knockout drum with an internal water spray system, a water recirculation pump and the water recirculation cooler. The , water cooler reduces the water temperature sufficiently to allow the internal spray system in the knockout drum to cool the VCM and condense much of the steam in the vapor stream. e After leaving the first stage of the water scrubbing system, the VCM vapor flows to the second stage of the scrubbing system and then to the rest of the recovery system in the same manner as during normal recovery. 3. Hydroquinone Injection The VCM removed from the reactor during recovery still contains * a small amount of initiator. As a result, the VCM will continue to polymerize, resulting in plugged recovery lines, charge lines, and recovered VCM storage tanks. Polymerization is significantly * reduced by the addition of an inhibitor such as hydroquinone to the VCM stream as it is being recovered. A 4.6 percent solution of hydroquinone in water is prepared in ,j***-*, the hydroquinone storage tank.

The hydroquinone solution is pumped by the hydroquinone injection pump into the suction of the recovery seal water pumps. The in jection pump starts and stops automatically with the seal water pumps. The metering pump has a variable stroke which can be adjusted manually to maintain the preset hydroquinone injection rate. 4. Recovery of Water Stripper The water stripper is to collect the various steam and water streams containing VCM from the four-reactor module. The emission recovery system is used to recover VCM vapor. The water is transferred to the V-11rwater strippers and recovered by the emission recovery system, E. Reactor Dump and Rinse After the reactor is recovered and steam stripped, the reactor inter lock selector switch is moved to the "dump" position. The appropriate dump valves are opened from the control room and the slurry flows by gravity to the dump system. The slurry passes through an enclosed vibrating slurry strainer where the PVC culls are collected until dump is completed. The slurry then flows to the slurry dump tank. The slurry transfer pumps transfer the slurry to the blend tanks. The dump tank level is automatically controlled. VAB.0001146659 1-3 A Operating Manual D*^7A5PVC Reactors Page 17 IX. GENERAL PROCESS DESCRIPTION (CONTINUED) E. Reactor Dump and Rinse (Continued) Near the end of dump, the reactor condenser is flushed with water by turning on the condenser rinse system from the board. Hot water Is pumped from the hot water tank by the hot water charge pumps through the cleaning nozzle in the reactor condenser. The rinse water mixes with any remaining slurry and is pumped with the slurry to the blend tanks flushing out the slurry transfer lines. The slurry strainer and the slurry dump tank are equipped with a water wash system to remove resin from the equipment between i> production of different types of resin. F. Cheat Wash and Rinse If it has been determined that the reactor needs cleaning, the reactor Interlock selector switch is moved to the "clean and rinse" position after the dump and rinse is completed. The chem wash solution is a caustic solution. The cleaning solution pump or spare pumpa the solution at 500 gpm from the cleaning solu tion tank through the cleaning solution heater to the reactor condenser spray nozzle. The reactor atmospheric vent must remain closed-to prevent splashing out of the reactor. Steam to the clean ing solution heater is automatically adjusted such that the exit temperature of the chem wash solution is 190F. When the level in the reactor is above the agitator blades (approximately 5,000 gallons) as determined by the level change in the cleaning solution tank* no more solution is added to system. Recirculation is then started with VAB.0001146660 4* mmmmmm* \ 1-3 A Operating Manual D-7**5PVC Reactors r Page 18 H. GENERAL PROCESS DESCRIPTION (Cont.) F. Chem Wash and Rinse (Cont.) the cleaning solution being pumped from the reactor at approximately 250 gpm and back to the reactor through the reactor cleaning nozzle. Large PVC particles picked up in the reactor cleaning process are removed from the cleaning solution in the cleaning solution strainer before entering the suction of the cleaning solution pump. When the Chem Wash has ended, the solution is pumped back to the cleaning solution tank at 500 gpm by the cleaning solution pump. For D-741, 742, 743, and 744, the process required ten minutes to fill the reactor through the condenser, five minutes to wash the reactor, and ten minutes to empty the reactor, for a total of twenty-five minutes. For D-745, the process requires a total time of forty-one minutes--twenty-one minutes to wash through the condenser, ten minutes to wash the reactor and ten minutes to empty the reactor. After the Chem Wa&h is completed, the reactor is rinsed with hot water from the hot water tank. The hot water is pumped by the hot water charge pumps to the reactor. The water first enters through the condenser clean ing nozzle and then the reactor cleaning nozzle. The Chem Wash and rinse system is manually controlled from the control room. The operator monitors the bullseye at the sewer drain to be sure the reactor is empty. When the reactor amps have dropped to the no load amps indicated on the ammeter. The lead operator opens the rinse valve for a short period ^ of time. By observing the water flowing from the bullseye he can determine that the reactor is empty. -^-.'^^1 ......................

Water Swirl If the resin formula calls for a water swirl, the reactor interlock selector switch is place in the "swirl" position after the Chem wash rinse is completed. Cold or hot water enters the suction of the hot water charge pumps, and is pumped through the reactor charge line into the reactor. When the water charge reaches a preset amount, the water charge system is automatically shut down. The reactor agitator is then used to swirl the water for approximately 25 minutes. The lead operator then drains the water to the sewer. This completes one reaction cycle; the reactor is now ready for evacuation. H. Water Collection System Various waste water streams from the process must be collected in an enclosed system for treatment. Water streams containing PVC and VCM from the recovery system, the VCM storage tanks, line and vessel purges, and miscellaneous flush and seal waters are intermittently sent to the blowdown tank. Whenlhe liquid in the blowdown tank reaches a level 22 inches from the top of the tank, a high level alarm sounds in the control room. The "A" operator also checks the level gauge on the tank twice per shift to be sure the level doesn't go above 22 inches from the top of the tank. The operator will then start the tank's transfer pump and send the waste water to the batchwater stripping tanks in the V-ll module. The waste .water is then stripped with steam and vapors are recovered with the emission recovery system. Once stripping has been completed, the wastewater is drained to the sewer.

Reactor Evacuation Evacuation of the reactor is required prior to charging in order to remove as much of the air as possible. Air is introduced into the reactor during previous phases of the reactor batch cycle since dump, rinse, and chem wash require that the reactor be vented to the atmosphere. Air in the reactor during reaction causes poor temperature control during polymerization and may alter the particle size of the resin. Evacuation is accomplished using one of the two-stage steam jet ejector systems. Evacuation is controlled by the lead operator from the board. The "A" operator must confirm that all process equipment is operating correctly during evacuation. Procedure 1. If the reactor has been opened, follow procedure given in the "Reactor Cleaning and Entry" section on how to close the reactor manhead. 2. The lead operator puts the interlock mode selector on "evacuation." 3. The lead operator checks to see that all valves are closed. 4. The lead operator opens the condenser recovery valve and the reactor evacuation valve. Then the lead operator opens the steam supply valve and the evacuation header valve to the steam ejector system to be used as follows. VAB.0001146664 1-3 A Operating Manual D-7U5FVC Reactors Page 21 III. OPERATING PROCEDURES (Cont.) A. Reactor Evacuation (Cont.) Procedures (Cont.) 4. Continued (a) For D-741, 742, 743, and 744, the operator will open valves CV-230 and CV-226. THis starts the ejector system located between D-742 and D-743. (b) For D-745 the operator will open valves CV-222 and CV-224. This will start the ejector system located between D-743 and D-744 reactor structure. The operator then opens the emergency cooling water valve, which supplies cooling water to the reactor coiidenser. NOTE: In the following steps, 5-10, the operators prepare the initiator for charge while evacuation is in progress. 5. The "A" operator will go to the initiator freezer and bring the specificed amount of initiator to the initiator injection pot. Extreme caution must be exercised by the "A" operator to be sure that no VCM is allowed to get back into the initiator injection pot. When a small amount of VCM is mixed with a large amount of initiator, an extremely fast reaction takes place giving off heat and pressure. To guard against this situation, the operator must know that he has an adequate water supply and pressure.

OPERATING PROCEDURES (CONTINUED) B. Reactor Precharge The reactor precharge procedure includes a series of precharge checks and precautions that must be carried out by the lead and ''A" operators. If the necessary precharge conditions are not met, the Modicon (a small computer which controls the automatic charge sequence) will not allow the automatic charge sequence to begin. It Is the responsibility of the lead operator to see that all precharge checks and precautions are carried out. He should also read the log book at the start of the shift, covering the period since he was last on the job. This will alert him to any changes in formula, mechanical, or operational procedures that may not have been passed on verbally. 1. Lead Operator Duties a. Check level in fresh VCM receiver to see tfyat it is ade quate for charge. 80% reading on the level gauge at the panel. 4 b. Drain water in the recovered VCM receiver to the water strip-- per. Valves from the recovered receiver are manually opened from the board until pressure rise in the blowdown tank indicates all the water Is out and VCM is being trans ferred. Valves are then manually shut from the board. c. Fill out the reactor charge sheet. d. Check the hot water tank level and temperature. Tank level should be 85% and the tank temperature 160F.

Record the readings on the charge sheet as they are trans mitted by the "A" operator. 2. "A" Operator Duties a Check Dura-Seal* level and pressure. There are two Dura- Seal* units. One supplies seal oil pressure to all five reactor agitator mechanical seals and the other is a spare and starts automatically when the operating unit has low seal oil level or discharge pressure. If both units fail, an emergency supply of seal oil Is provided by the emergency seal oxl drum that is nitrogen pressurized. Valves must be opened manually at the unit if the emergency seal oil system is used. A *Registered Trademark VAB.0001146669 1-3 Operating Manual D-7U5 PVC Reactors Page 26 III.

"A" Operator Duties (Continued) NOTE: When the primary and spare Dura-Seal* oil units are down and the emergency system is in operation, reactors are not to be charged until at least one of the DuraSeal* oil units Is operating. The emergency system is designed to be a backup system that should be used short terra only. When one of the Dura--Seal* oil units is not in operating condition, inform the lead operator so that repairs can be made. The seal oil level should be checked in both units. The discharge pressure should be checked and be in the range of 205-250 pslg. If the pressure falls below 205 psig, the spare unit will automatically start up and the primary unit shut down. The spare unit will also automatically start up and the primary unit shut down when a low seal oil level is detected in the primary unit. to the lead operator.

The reactor charge is one of the most critical operations in terms of product quality. Care must be taken to assure that all the raw materials are added in the proper order and amount. Procedure 1. When evacuation and precharge checks are complete, the lead operator can move the interlock mode selector to "charge." 2. The lead operator should take the following steps and see that the following conditions are met before charge: a. VCM transfer should be in auto. b. Recovered VCM charge should be in auto with either the primary or spare pump selected for charge. c. Fresh VCM charge should be in auto with either the primary or spare pump selected for charge. d. Hot water charge should be in auto. e. Colloid charge should be in auto with either the primary or spare pump selected for charge. f. Select recipe to be charged by dialing recipe number on the recipe selector on on the board. g. Push the meter reset button, which resets all charge meters.

The charge light will now come on if all the following conditions are met: (1) The fresh VCM storage tank, hot water tank, and colloid charge tank all have a level adequate for one complete charge. (2) One reactor is in charge mode. (3) The high pressure service water header is at least 150 psig. (4) The reactor being charged has at least 28.5 inches Hg vacuum. (5) The initiator injection pot is at least 180 psig. 3. When a charge light is obtained on the panel, the lead operator will inform the "A" operator to stand by for breaking vacuum. The lead operator will break vacuum by: 4 A a. Manually opening the reactor VCM charge valve from the board. I b. Manually opening the reactor charge valve from the board. c. Turbine meters will start counting as VCM flows into the reactor. d. As soon as a positive pressure is indicated in the reactor, close the VCM charge valve. VAB.0001146673 Operating Manual D-7^5 PVC Reactors Page 30 1-3 III. OPERATING PROCEDURES (Continued) C. Reactor Charge (Continued 4. The "A1* operator will then watch the pressure gauge at the top of the reactor. When the pressure rises above zero, start checking the following: a. Inspect manhead visually and listen for escaping vapor. b. Check safety disc gauges for pressure. Any pressure indicates a leaking or ruptured disc. c. Turn flush water (injection water) on sprayhead. The purpose is to keep spray heads free of resin. Set rate according to recipe. d. If all checks okay, notify lead operator. If not, notify lead to hold on charge until problem can be corrected. 5. The lead operator can now push the charge button. In rapid sequence, the following occurs: a. Reactor water charge valve opens. b. "A" hot water pump starts, valves open, and water starts into the reactor. c. The valves from the fresh VCM receiver to the VCM charge pump and discharge valve open. d. At set point No. i on water meters: A *Registered Trademark VAB.0001146674 1-3 Operating Manual D~745pvc Reactors Page 31 III. OPERATING PROCEDURES (CONTINUED) C. Reactor Charge (Continued) Procedure (Continued) (1) "B" hot water pump starts and discharge valve opens. (2) The colloid charge pump discharge valve will open and pump will start. The preset amount of colloid will be pumped into the reactor. When the colloid meter set point is reached, the colloid charge pump will cut off and the discharge valve and reactor colloid charge valve will close. NOTE: The lead operator will turn on reactor jacket steam during colloid and water charge to assist reactor heatup. e. At set point No. 2 on water meter, the reactor VCM charge valve opens and the VCM and recovered VCM charge pumps start. f. At set point No. 3 on the water meter, MB" hot water pump stops and discharge valve closes. This allows time for all VCM to be charged to the reactor before the water charge is completed. NOTE: A partially plugged filter pack can cause slow VCM flow, *nd it may be necessary to cut off MAn hot water pump also. If this should happen, be sure to have a minimum of 50 counts left on water charge meter. This Is enough to clean lines * and manifold of VCM. When the VCM is within ten counts of being complete, put HAM and "B" hot water pumps back on automatic and complete the charge. A VAB.0001146675 Operating Manual D-745 PVC Reactors Page 32 1-3 III. OPERATING PROCEDURES (Cont.) C. Reactor Charge (Continued) NOTE: When a filter is known to be fouled, isolate and switch to the spare unit. If you continue to try to force VCM through fouled filters, the high pressure will cause the filter elements to collapse and greatly increase the time taken to change them out. Collapsed filters also will cause a gel problem affecting the quality of the resin. g. When VCM meters reach the set point (two meters running in tandem, first to reach the set point cuts pump off and closes valve), the VCM pump, outlet valve, inlet and discharge valve to VCM charge pump, and reactor VCM valve close. This action also starts "BM hot H^O pump and opens discharge valve. h. At set point No. 4 on the water meters, "B" hot water pumps stop, and the valves close. i. At set No. 5 in the water meters "A" hot water pump stops and the valves close. At this time the main dump valve also closes. 6. When the automatic charge sequence has been completed, it is safe to charge the initiator. 7. The "A" operator charges the initiator by opening the initiator reactor charge valve and flushing the initiator into the reactor with 50 counts of high pressure service water. 8. The lead operator will now record the final recator temperature. Adjust reactor temperature set point to setting called for in the formula and put temperature controller in "auto" position. A VAB.0001146676 x Operating Manual \ D-745 PVC Reactors Page 33 III. OPERATING PROCEDURES (CONTINUED) D. Polymerization Polymerization is the phase of the reactor cycle in which liquid + VCM is converted into solid PVC. This portion of the reactor cycle is mainly accomplished by accurate instrumentation. The primary area of responsibility for the lead operator is coordination of the activities of the "A" operator. The "A" operator is required to kill the reaction when polymerization has progressed to the point that product quality is satisfactory. 1. Lead Operator Duties a. Change the interlock mode selector to "polymerization." ( Monitor the temperature and pressure closely until the reactor reaches the desired set point and lines out. b. Cut off steam valve to jacket at two to four degrees below set point, depending on the rate of temperature rise. c. Have the "A" operator sample the reactor 1 hour after reading heat up. a fresh-air mask must be worn and personnel cleared of the general area before sample is taken, d. Examine the resin. At this stage the resin shoiild be formed into individual separate particles. Notify the shift super visor if you notice the following: (1) Stringers - Resin particles are stringy and stuck together. (2) Hard Particles - Gritty resin particles which are harder ahd larger than most. / t VAB.0001146677 1-3 Operating Manual D-745 PVC Reactors Page 34 III. OPERATING PROCEDURES (CONTINUED) D. Polymerization (Continued) 1. Lead Operator Duties (Continued) If either of the above conditions are observed, have the "A" operator take samples every fifteen minutes until the shift supervisor makes the decision as to what eu corrective action should be taken. e. It may become necessary to remove the inerts. Inerts in the condenser will cause the reactor pressure to rise as they blanket the condenser and do not allow VCM vapor to be condensed. Under these conditions, less heat can be removed even though the condenser water flow will be full open. Vent the inerts through the main condenser valve to the recovery system. Start the compressors and put the pressure controller in manual and close the control valve. i Open the reactor condenser valve and recovery valve. Set the controller on 35 psig and put it back in automatic. f. Irregularities during polymerization: (1) Slow Heatup--May be caused by weak or no initiator. Slow heatup can also be caused by no steam on reactor jacket or the cooling water valves may be open. Contact the shift supervisor if this condition persists. VAB.0001146678 Operating Manual ^""^^PVC Reactors Page 35 III. OPERATING PROCEDURES (CONTINUED) D. Polymerization (Continued) 1. Lead Operator Duties (Continued) (2) Long Reaction Time--Caused by low initiator level, weak initiator, long heat up, low reactor temperatures or chem wash solution setting or chem wash solution in the batch. If there is only slow reaction and the resin checks okay, the shift supervisor will give word on what to do. If caustic is in the reactor, the batch will turn slightly yellow and coarsen. If this is found to be true, kill immediately with the amount of short stop solution speci fied in the formula. (3) Simultaneous Temperature and Pressure Rise--Check cooling trater temperature and valves. The reactor is producing more heat than the cooling water can remove. Also could be an overcharge of initiator. 4 Notify shift supervisor for instructions. (A) Simultaneous Temperature and Pressure Drop--The cooling water valves are probably wide open. This happens more often in freezing weather when relays freeze up. Throttle manual valves until malfunction is found and corrected. (3) Agitator Kicks Out or Power Failure--Most power failures are of short duration (seconds to two minutes), and the reactor pressure does not have time to build to a dangerous level. If outage is prolonged, the pressure will build. VAB.0001146679 Operating Manual D-745 pvc Reactors Page 36 1-3 A III. OPERATING PROCEDURES (CONTINUED) D. Polymerization (Continued) 1. Lead Operator Duties (Continued) If this situation occurs, follow the procedure in Section III.D.3 which outlines action to be taken during emergency shutdowns (such as during a power failure). 2. nA" Operator Duties a. When charge is complete, recheck water injection rates through the cleaning nozzle and seal flush. b. On instruction from the lead operator, resin samples will be taken from the reactor. This normally occurs 1 hour after heat up. If the first sample shows formation of undesirable resin particles, additional samples may be called for every fifteen minutes until a decision is made about what should be done with the batch. When taking a sample from the reactor a fresh air mask must be worn and personnel cleared of the general area. c. When the lead operator instructs the "A" operator to do so, the batch is killed by adding short stop solution to the reactor. The amount of short stop solution and the procedure for adding it depends on the product. The kill procedure is as follows: 5305 (normal) -- 1% gallons AMS 5305 (CTA) 5425 5465 5385 -- 3% gallons AMS/3% gal. Naugard -- 1% gal. AMS/2% gal. Naugard initially and again at 170F. -- 2% gal.

Polymerization (Cont.) It is very important that the proper amount of short stop solution be added since it effects the quality of the resin. High pressure service water is used to pressure the short stop solution from the initiator put into the reactor. 3. Emergency Shutdown The following steps are to be taken during emergency shutdown: a. 1. Use the AMS emergency kill system for killing each reactor. Each reactor has a pot located at grade beside each reactor, containing AMS. The AMS is injected into the head space of the reactor with nirtogen by opening the appropriate control valves, from the control room. The hand switch for the control valves for each reactor is located next to the agitator start-stop handswitch on each reactors control station. Refer to the operating manual for the AMS Emergency Kill System. 2. If the AMS does not stop the reaction, use the nitric oxide (NO) short stop system for killing each reactor. There are six cylinders of NO that can be released for each reactor D-741, M2, 743 and 744. D-745 has twelve cylinders of NO which can be released. The NO system can be activated at the reactors by manually opening the correct valves. A VAB.0001146681 Operating Manual D-745 PVC Reactors Page 38 IH. OPERATING PROCEDURES (Cont.) D. Polymerization (Cont.) 3. Emergency Shutdown (Cont.) b. Use nitrogen to pressurize the Dura-Seal* unit emergency seal oil drum and the mechanical seal purge water surge drum. The valves connecting the emergency seal oil and seal water drums with their respective systems must be opened manually. c. There will be sufficeint air in the air system surge tank to operate valves for approximately fifteen minutes. It will be necessary to use the nitrogen backup system to operate valves after fifteen minutes. The surge tank should be valved off before the backup nitrogen system is activated. d. Monitor each reactor for pressure rise. If the pressure con tinues to rise, the following steps are to be taken: (1) Equalize the reactor with any other empty or killed reactor of the same type product. (2) If the pressure still continues to rise, vent through the main condenser valve to the recovery system and the re covery system to the recovered VCM receiver. (3) If this will not relieve the pressure buildup, then equal ize the reactor with a reactor of different type resin. * Registered Trademark VAB.0001146682 1-3 A Operating Manual D-745 pvc Reactors Page 39 III. OPERATING PROCEDURES (CONTINUED) D. Polymerization (Cont.) 3. Emergency Shutdown (Cont.) d. (4) When 1, 2, and 3 alone fail to relieve the reactor pressure, the relief valve vent system will allow the reactor to vent off and on thru the relief valves to control the pressure. NOTE: Step (4) is to be the last resort. Under the new EPA law, any venting must be reported and could result in a fine. The foilwing guidelines, when followed, will control a runaway reactor and prevent a VCM release . The NO system is to be activated if either one of the parameters is exceeded.

A Scott Air Pak must be worn while killing a reactor with the NO short stop system. E. Recovery and Steam Stripping The reactor is ready for recovery when certain conditions are reached in the reaction process. The conditions under which recovery will start are: Pressure Drop -- There is not enough unreacted VCM left in the reactor to maintain run pressure. A pressure drop is accompanied by a drop in the cooling water flow to the reactor jacket and condenser. Runaway --Reaction has increase to the point that it has outrun the capabilities of the cooling water to control. Temperature and p re ss^f^-QO^i46683 Operating Manual D-745 pvc Reactors Page 40 III. OPERATING PROCEDURES (CONTINUED) E. Recovery and Steam Stripping (Cont.) Runaway (Cont.) both rise when this occurs Follow instructions on each product formula as to the exact conditions at which the reaction is killed. Temperature Rise-Pressure Drop-- This is the ideal recovery situation and indicated proper initiator loading. The reaction will peak and slightly out. run the capabilities of the cooling water. This situation gives the best recovery conditions since there is less VCM to be recovered and more converted to resin. Quick-Kill-- A reactor is sometimes killed on specific products to meet certain customer specifications--lower dry time (higher plasticizer absorbtion ). The reactor is killed with a specified amount of the short stop solution at a specified set of conditions The short stop solution mixture stops the reaction chain. On a quick-kill batch, it is very important to guard against resin carryover to the recovery system. An injection of defoamer will help to control foaming. A fast recovery is also important and will affect the dry time. 1. M Aa II Operator Duties When specified in the formula are met, the A operator will take the following steps: a. Check the hydroquinone injection sytem to make sure that the proper valves are open and hydroquinone level is adequate, b. Check the blowdown tank level and pressure.

Chem Wash and Rinse Chem wash and rinse is not done as a matter of routine on all reactors however, if it has been determined that chem wash is needed, the formula states what the lead operator is to do. After the reactor has been rinsed during the dump cycle, it is ready to be chem washed. The chem wash cycle is necessary to remove polymer buildup from the reactor condenser, walls, baffles, and agitator. If polymer buildup is allowed to remain in the reactor, it continues to grow with each successive charge. Buildups will contribute to high gel, low quality resin, and will make reactor dumping very difficult if they get large enough to break off and plug dump valves and lines. Operators must exercise caution during chem wash due to the caustic in the solution. If any solution gets on a operator, flush immediately with water. Caustic feels slick to the touch and will start burning the skin just a few seconds after contact.

The lead operator will check and make sure the reactor sewer valve is closed. 2. The lead operator will then place the interlock mode selector switch to "clean and rinse." 3. The lead operator then checks to see that the cleaning solution tank, 45-767, is at least 85 percent full. 4. The lead operator then opens the valves from`the cleaning solution pumps, 72-989 or 72-899, to the reactor condenser cleaning nozzle. The atmospheric vent on the reactor should be closed. All other reactor valves are closed. 5. The lead operator then opens the suction valves, CV-873, for the cleaning solution pumps, 72-898 or 72-899. 6. The lead operator will then turn on one cleaning solution heater temperature controller is set at 190F. 7. The lead operator will then turn on one cleaning solution pump 72-898 or 72-899.

Hydroquinone Solution Makeup Hydroquinone is injected into the recovery system to short stop the chain reaction and polymerization of vinyl chloride. If the hot VCM gases are allowed to flow through the recovery lines with out any inhibitor, they continue the reaction that was started in the reactor and rapidly fill and plug the recovery lines. Plugged lines in the recovery system are very time consuming to pull and clean and cause considerable amounts of downtime. Adequate and accurate injection of hydroquinone eliminates this problem. Hydroquinone (commercial name Tecquinol*) comes in a powder form and must be put into a solution with water for our use. When the hydroquinone solution level is low, as determined by the low level alarm LA-733 in the control room and/or by the hydro quinone storage tank sight glass, a new batch is to be made . Each batch should last approximately one month.1 1.

Initiator Handling and Storage In the conversion of vinyl chloride monomer to polyvinyl chloride resin, an initiator is needed to start and help sustain the reac tion process. The Aberdeen plant uses peroxide-type initiators. The physical properties of the type resin needed determines the type of initiator to be used. All of these products must be kept in cold storage because of rapid dangerous decomposition rates at room temperatures. The initiator is a skin and eye irritant and must be handled accordingly. Safety precautions for all types of initiator are basically the same, with some differences in handling temperatures and explosive limits. 1. Safety Precautions in Handling Initiator * a. Wear full face shield when handling an open container. 11. Avoid contact with skin or clothing (will bleach out clothes). c . Do not leave initiator unattended when not under refriger ation. d. If Initiator is spilled, soak up with absorbent material, such as vermiculite, and spread thinly in an isolated area. e. Dispose of empty containers immediately. Leave cap off and split the side of this container and store away from the unit in an open area. VAB.0001146705 Operating Manual D-745 pvc Reactors Page 62 III. OPERATING PROCEDURES (CONTINUED) L.

Do not allow the amount in the reactor area freezers to exceed one shift's comsumption. g. If a partial or full jug of initiator is found sitting out, it may be water, but always handle and dispose of just as if it were initiator. h. If spilled on skin area, wash with large amounts of water. i. If splashed in the eyes, flush with water for fifteen (15) minutes and notify your supervisor. Do not use oils or salves on the eyes. j. Should any initiator catch on fire, use water to cool the surrounding area. However, if the fire is spread ing and likely to ignite other initiator set the portable fire monitor and get out of the area, since an explosion is very likely. 2.

Design and Operational Functions Each freezer is provided with two refrigeration units each which are capable of maintaining the desired freezer temperature. Both units can be run simultaneously to allow a check on com pressor operation. The temperature element in each freezer is connected to a mer cury switch which starts and stops the compressor. These are adjustable and can be set for different temperatures. Each compressor has a timer which activates a solenoid valve in the hot gas line to send hot gas directly to the evaporator to allow for the defrost cycle. The fan normally runs with the compressor but is off during the defrost cycle. The east, middle, and west walk-in freezers defrost every six hours, and the chest freezer defrosts every eight hours. The water-cooled condensers on each compressor in the west compressor shed have water bypass to allow continuous flow and prevent freezeup during cold weather. The condensers also have inlet and outlet valves to allow for acid cleaning. Condenser cooling water is normally supplied by and returned to the cooling tower. During shutdowns and power outages, a bypass valve from the well to city water can be opened to supply water pressure. If the condensers are put on the well open the block valve in the manhole at the west end of the cooling tower to divert the water to the sewer.

When internal job is completed, remove scaffolding from the reactor and store neatly. Remove any loose buildup on the reactor bottom and close the bottom mnnhead. o. Clean up any debris, rags, etc. The job is never complete until the area is clean. VAB.0001146720 Operating Manual D-745 PVC Reactor Page 77 III. OPERATING PROCEDURES (CONTINUED) 0. Housekeeping Guidelines Good housekeeping is a major portion of any task to be undertaken, and no task can be called complete until the work area has been cleaned. Return all tools and materials used to their proper place and do not leave lying around to create a safety hazard. The housekeeping of the reactor area is the responsibility of all people working there. I~3 A VAB.0001146721 EQUIPMENT INDEX VAB.0001146722 1-3 A Operating Manual D-745 PVC Reactors Page 78 IV.

ALARMS AND SAFETY EQUIPMENT A. Continuous Flow Fresh Air System TM -- 11 -- ----- -- -, ** r In order to provide personnel protection, a continuous flow fresh air system has been installed. This system consists of p< -rsonne 1. fresh air masks and a constant flow breathing air supply. The supply lines are piped to all affected areas of the plant. The individual hookup stations consist of quick connect/disconnect- type fittings. The individual lines to the designated areas are designed to allow a minimum flow of 6 SCFM to each mask at approximately L0--15 psig. An air pressure regulator, shutoff valve, and an air filter are provided at the piping header to each individual area. The air supjly system utilizes two Nash compressors supplying 100 SCFM each at a maximum pressure of 80 psig. Each compressor will supply about fifteen masks with air at one time. The com- i- pressors normally are both in operation at the same time, except in cases of mechanical failure. The system is equipped with both visable and audible low pressure alarms which are activated at 50 psig. The revolving beacon light is mounted on a pole to give wider visibility, and the hor* is mounted at the compressor. An on-off switch is provided nr each compressor.

A* Continuous Flow Fresh Air System (Cont.)* 1 The following job operations will REQUIRE the wearing of a continuous flow fresh air mask supplied through the fresh air lines or a Scott Air Pak: 1. Opening any piece of process equipment in vinyl chloride service including: a. Pumps b. Compressors c. Filters d. Vessels e. Piping 2. Opening a Lenape manway on a reactor without using steam jet evacuation. 3. Entering vessels or may confined area that have contained vinyl chloride. 4. While on top of the large blend tanks which are regulated areas. 5. When using the portable vinyl chloride detector to pinpoint a vinyl chloride leak detected by the continuous monitoring system when the VCM conentration is expected to exceed 10 ppm. 6. Reactor dumping normally does not require the use of a fresh air respirator. Abnormal conditions which would require a fresh air mask are: a. When working on a plugged reactor dump valve or line. b. Dumping a coarse batch. c. Inoperative Sweco exhauster. 7. Sampling of reactors, VCM railcars, or storage tanks. 8. The heated water vapor coming from vents in the old unit sewer during pump-out of the blowdown tank contain concentrations of VCM above 1 ppm. If an employee must perform work in an area where these vapors exist, an air mask must be worn. VAB.0001146768 A 1-3 Operating Manual D-745 PVC Reactors Page 122 VI.

ALARMS AND SAFETY EQUIPMENT (CONTINUED) C. Firewater System The firewater system consists of a deluge system, combustible hydrocarbon analyzer, and fire monitors with hose connections 1. Fire Monitors The fire monitors are normally supplied from the city water system. A tie-in with the firewater system allows the fire monitors to operate off either water system. There are six fire monitors located around the perimeter of the recovery building and reactor area. 2 Hydrocarbon Analyzer A continuous combustible hydrocarbon analyzer is used to detect VCM When the VCM the set point, the deluge system is activated automatically 3 Deluge System The deluge system is normally supplied from the firewater syste It can be operated on process water. The deluge system is a sprinkler system which will cover the reactors, dump system. VCM recovery building with a water spray. The deluge system is designed to lower VCM concentrations in the reactor and recovery building area in the event of a VCM leak and as a sprinkler system to help put out fires. The deluge system can be acti vated manually, by the combustible hydrocarbon analyzer, or by thermal sensors. VAB.0001146778 1-3 Operating Manual D-745PVC Reactors Page 132 VI. ALARMS AND SAFETY EQUIPMENT (CONTINUED) C. Firewater System (Continued) 3. Deluge System (Continued) The revised firewater system contains three new post indicator valves (PIV) and one PIV was relocated. These are valves which have indicators on them to show whether the valve is open or closed. These valves are used to direct water to either the D-700 reactor area or the V-ll area. The valves are located at: 1. The southwest corner of the new cooling water tower. 2. East wall of the V-ll building. 3. Two are located at the northwest corner of the intersec tion of the entrance road and second street. D. Fixed Point VCM Monitor A fixed point VCM monitor is used to detect VCM and record the VCM concentration at various locations in the reactor and recovery building. The readout is on a chart in the control room. A VAB.0001146779 I equipment opening PROCEDURES * VAB.0001146780 A 1-3 Operating Manual D-745PVC Reactors Page 133 VII. EQUIPMENT ENTRY PROCEDURE EPA standards for VCM emissions and OSHA regulations on personnel exposure to VCM require that certain operating procedures be followed when there is the possibility of VCM emission to the atmosphere or personnel exposure to VCM. For this reason and to ensure safe working conditions at all times, the "Engineering and Work Practice Control Program for the Reduction of Employee Exposure to Vinyl Chloride" manual should be consulted whenever equipment in the reactor area is opened for any reason. This manual contains a list of detailed procedures as well as safety precautions for equipment opening. Every vessel has an entry check list that must be filled out by the Shift Supervior. The entry check list contains a building list for opening a vessel. VAB.0001146781  ^ APPENDIX I i i i i i l* i l.

Purpose The purpose of the Emergency Kill System is to increase the re liability and effectiveness of equipment and procedures used to safely and quickly stop the polymerization reaction in the reactors. Stopping the reaction prevents excessive pressure buildup which can cause emergency releases through the reactor relief valves. This system allows any or all reactors to be shut down in an orderly and safe manner. This manual describes the system and the operator's responsibilities for operating and maintaining the system. B. Operator Responsibilities The operator is responsible for producing quality products in a safe and efficient manner. He fulfills his responsibilities by knowing the following and passing a written exam: 1. Understanding how his equipment functions. 2. Understanding what role each piece of equipment plays in the process. 3. Keeping a close and regular check on equipment. k. Knowing how to spot malfunctions and correct them. 5. Keeping his area of responsibility safe and clean. 6. Keeping complete and accurate records. C. Process Information The polymerization reaction of VCM to form PVC gives off heat and accelerates as temperature increases. As the temperature increases, the reactor pressure also increases. It is there fore necessary to remove the heat of reaction with cooling VAB.0001146816 Page 2 1-3 KL b I. INTRODUCTION (CONTINUED) C. Process Information (Continued) water in the reactor jacket and condenser. Reactor agitation is also required to maintain uniform reactor mixing and efficient heat removal. If reactor cooling and/or agitation is lost, the reaction must be stopped. Failure to do so would result in a runaway reaction with increasing temperature and pressure. The reac tor pressure could increase until the rupture disk/safety valve assemblies would vent the reactor contents to the atmosphere. The new Emergency Kill System provides the capability of in jecting up to 25 gallons of killing agent into each reactor either remotely from the control room or manually at the re actor top head platform. Killing agent can be injected into a reactor as soon as agitation is lost to take advantage of mixing caused by residual swirling motion. Maintaining cool ing water flow after loss of agitation will also help mixing by refluxing in addition to removing heat of reaction. VAB.0001146817 Page 3 1-3 I I. GENERAL PROCESS DESCRIPTION Refer to the attached PS I diagrams for the complete system layout for each reactor area. Emergency kill injection pots are provided at grade level for each reactor. All injection pots are to be maintained at 300 psig pressure using high pressure nitrogen cylinders. A separate nitro gen cylinder and spare are provided for each injection pot. Level gauges and pressure gauges are provided on each pot in addition to board-mounted low pressure alarms and low level indicators. The A operator should check the appropriate injection pot level and pressure before starting each reactor charge sequence. Killing agent can be injected into the reactor either remotely by the lead operator or locally by the A operator. Normally, the emergency kill system will be activated from the board to minimize time and maximize mixing. One switch for each reactor operates automatic double block valves at the reactor top head level. Placing the switch in automatic mode opens the valves and allows a low level switch in the injection pot to close the valves. Placing the switch in the momentary-contact manual mode also opens the valves but the valves close when the switch is released. Each injection pot low level switch also activates a local light at the manual injection point at the reactor top head level. The auto matic closure of the remote injection valves and the local low level indicator light are provided to prevent nitrogen from being injected into the reactor, blanketing the condenser and reducing coo ling efficiency. VAB.0001146818 I I. GENERAL PROCESS DESCRIPTION (CONTINUED) Page ^ Emergency injection headers are provided at the reactor top head level in each reactor area. These headers will allow any injec tion pot to be used to kill any reactor in each area or to Inject additional killing agent if needed. The procedure requires two hoses, one to connect an injection pot to the header, and one to connect the header to the reactor. Killing agent can then be in jected locally by the A operator or remotely by the lead operator. It should be noted that when the emergency injection header is used, the injection pot low level switch will neither automatically close the remote injection valves nor light the appropriate local indicator light. Caution should be taken to prevent charging nitro gen into the reactor. The remote injection automatic valves will be operated by nitrogen supplied by a high pressure nitrogen cylinder and spare. A boardmounted low pressure alarm is provided for each area to alert the board operator when the cylinder in use has dropped below 600 psig. A cylinder with less than 600 psig pressure does not contain enough nitrogen to operate the control valves and should be immediately changed out with a full cylinder. 1-3 VAB.0001146819 Page 5 SAFETY The operation of the emergency kill system does not present any extremely hazardous situations. In fact, it's main purpose is to reduce the potential for having hazardous situations in the reactor area. However, some potential hazards are present and precautions should be taken to prevent serious incidents. A. The killing agent AMS has been in use for some time in the plant and the operators should already be familiar with the corresponding safety hazards and proper handling procedures. The attached vendor literature describes chemical properties and safe handling procedures. It should be emphasized that AMS is highly reactive in the presence of the peroxide ini tiators used in the plant. AMS AND INITIATOR SHOULD NEVER BE MIXED UNDER ANY CIRCUMSTANCES. B. The new AMS injection pots will be maintained at 300 psig by high pressure nitrogen cylinders. Due caution should be exer cised in the handling of nitrogen cylinders. Operators should avoid damaging the outlet valves on these cylinders. The AMS injection pots will contain AMS under 300 psig pressure, so proper safety precautions should be taken while working with or near these vessels. The injection pots must be depressurized before the block valves on the pot funnel or AMS fill line are opened. The nitrogen supply to a pot should be turned off at the pot prior to vent ing the pot. The pots should only be vented through the bleed valve on the pressure gauge/pressure switch piping on the top of the pots. POTS SHOULD NEVER BE VENTED THROUGH THE FUNNELS ON THE SIDE OF THE POTS. VAB.0001146820 1-3 Page 6 III. SAFETY (CONTINUED) C. The rupture disk and relief valve assemblies for each injec tion pot are set to relieve at 400 psig, the vessel design pressure. Since nitrogen bottle regulators occasionally leak through, a potential exists for overpressuring the injection pots and causing the rupture disk to burst. Even if the killing agent didn*t spray out when the relief devices opened, it is probable the relief valve would not completely reseat and the nitrogen bottle would slowly depressure through the pot and relief valve to atmosphere. The outside operator should routinely check injection pot pressures to insure it is neither too low nor too high. D. The AMS killing agent is a volatile hydrocarbon, and thus fire and explosions are theoretically possible. Precautions should be taken to prevent spills and excessive accumulation of flam mable vapors. E. Since the injection pots are connected to the reactors, a poten tial exists for backing VCM into the pots. This poses no serious immediate problem since the AMS would kill any reaction that was occurring. However, it could present an exposure problem later when the injection pot is opened. The injection pots should be maintained at 300 psig pressure except when re filling. F. Finally, operators should keep in mind that this system will be used when the p1 ant is in an upset condition, i.e., power failure, loss of cooling water, reactor runaway, etc. It is VAB.0001146821 1-3 Page 7 rt SAFETY (CONTINUED) critical that this system must operate properly in such an emergency. System maintenance and operator familiarity with this system are equally important factors ensuring the dependability of this system. VAB.0001146822 1V. OPERATING PROCEDURES 1-3 A Page 8 A. Injection Procedures 1. The emergency kill system should be activated under the fol lowing circumstances: a. Extended loss of cooling water to a reactor in poly merization mode. b. Extended loss of agitation to a reactor in polymeriza tion mode. When agitation Is lost, it is Important to kill the reaction as soon as possible. The reactor contents will continue to swirl for about four minutes after agitator shutdown, and AMS injection during this period is much more effective. c. A runaway reaction with increasing temperature and pres sure which is not responding to small AMS Injections (short stop) from the initiator charge pot. d. Any other circumstance considered by the operator to represent a significant chance of over pressuring the reactor or affecting safe operation of the plant. 2. The emergency kill system must be activated If the reactor reaches the following pressures for the following products: d * 5305 with CTA b. 5305 without CTA c. A11 other products 3. Lead Operator Duties 155 psig 165 pslg U5 pslg a. The lead operator should remotely inject AMS into the polymerizing reactors which require killing by placing the appropriate hand switches in the AUTO mode. \ VAB.0001146823 Page 9 1-3 1V. OPERATING PROCEDURES (CONTINUED) A. Injection Procedures (Continued) 2. Lead Operator Duties (Continued) b. The lead operator should then check for confirmation of AMS injection from the board-mounted low level indicat ing lights, and from the A operator via radio. In jection time should be about 30 seconds. The board- mounted injection pot low pressure alarms will normally be tripped during AMS injection. If the pressure and level alarms are not tripped, the automatic AMS injection line may be plugged requiring manual injection. c. After AMS injection, the lead operator should closely monitor the reactor temperature and pressure. If cool ing water has been lost, he should take steps to restore cooling as soon as possible. d. If additional killing is required, the momentary-contact manual switch can be used. Caution should be exercised to prevent nitrogen from entering the reactor and blanket- ing the condenser. j e. If excess nitrogen does enter the reactor, the condenser should be vented to the recovery system. 3 A Operator Duties a. The A operator is responsible for field-checking AMS injection to each of the reactors to be killed. He should confirm that the injection pot level is at the low level mark on the level gauge. Too high a level VAB.0001146824 .. i .. . Page 10 1-3 A IV. OPERATING PROCEDURES (CONTINUED) A. Injection Procedures (Continued) r 3. A Operator Duties (Continued) means not enough AMS was injected. No level may mean nitrogen has entered the reactor. The A operator should also check the -pressures I of the nitrogen cylinders used for AMS injection. Any cylinder with a pressure lower than 750 psig should be changed out to allow for a second AMS in ject i on. c. After checking the injection pot and nitrogen cylinders, the A operator should proceed to the reactor top level to confirm that the automatic injection valves i are closed. If the valves are open, he should man i it ually block in the line and inform the lead operator that nitrogen has entered the reactor. It may be necessary to vent nitrogen to the recovery system to maintain reactor cooling. d. If the automatic injection system failed to work, the A operator should manually inject AMS to the re i s actor. He should open the manual double block injection valves, wait for the injection pot low level I indicator light to light, then immediately close the double block valves. The valves should also be immediately 1 closed if the line begins to vibrate from flowing nitrogen. VAB.0001146825 Page 11 1-3 OPERATING PROCEDURES (CONTINUED) A. Injection Procedures (Continued) 3- A Operator Duties (Continued) e. If additional injection is required, the A operator should prepare the emergency injection header for use. This header is supplied to allow any injection pot to be used for any reactor. This is accomplished by connect ing one hose from a full and pressurized pot to the header and connecting a second hose from the header to the appropriate reactor. Injection can then proceed either locally or from the board. Caution should be exercized when using this header since the injection pot low level switches will not work correctly and nitrogen may enter the reactor. f. As soon as possible after injection, the A opera tor should refill the empty AMS pots and prepare for a second injection if needed. 1. Close the block valve on the nitrogen supply line at the pot. 2. Depressure the pot through the pressure gauge vent valve. 3* Refill the pot with AMS from a 55-gallon drum using the air operated drum pump supplied with the system. An alternate filling procedure is to manually pour AMS into the funnel on the side of the injection pot. VAB.0001146826 Page 12 I-3 /. If IV. OPERATING PROCEDURES (CONTINUED) A. Injection Procedures (Continued) 3 A Operator. Put 1 es .(Continued) f. (Continued) 4. Block in the pot and repressure with nitrogen from the nitrogen bottles. g. Radio communication between the lead operator and the A operator should be maintained. The A operator should inform the lead operator how the system is operating and what is being done in the field. The lead operator should keep the A operator Informed of reactor pres sures and any apparent need for additional AMS injec tion. B. Routine Operation 1. A reactor should not be charged unless its AMS injection system is in proper operating condition. It is the respon sibility of the A operator to check this in the field and notify the lead operator, prior to each reactor charge. The following items should be checked immediately before each charge: a. The AMS level in the injection pot should be at the full mark on the level glass. b. The pressure in the injection pot should be 300 psig. This should be checked both on the injection pot pressure guage and on the nitrogen cylinder regulator outlet pressure guage. VAB.0001146827 1-3 Page 13 A IV. OPERATING PROCEDURES (CONTINUED) B. Routine Operation (Continued) c. The block valve in the AMS line near the injection pot should be fully open. d. The block valve in the AMS line at the reactor top head level near the hose connection should be fully open. e. Both block valves on the manual AMS injection line should be fully closed. If any of the above conditions are not met, they should be corrected before the reactor is charged. 2. To insure proper operation of the system, the following items should be checked by the A operator at the beginning of each shift: a. The pressure of the nitrogen cylinders being used for AMS injection should be at least 1200 psig. Cylinders with lower pressures should be changed out with full cylinders. EMPTY BOTTLES ARE NOT TO BE LEFT IN THE BOTTLE RACKS. b. The pressure of the nitrogen cylinder being used to actuate the automatic AMS injection valves should be at least 600 psig. Cylinders with lower pressures should be changed out with full cylinders. The pres sure on the outlet of the regulator for this cylinder should be 100 psig. VAB.0001146828 Page 14 IV. OPERATING PROCEDURES (CONTINUED) B. Routine Operation (Continued) c. The pressure gauges between the double block valves on both the automatic and the manual injection lines should routinely be bled to 0 psig. If pressure sub sequently builds up on these guages, it indicates that one or both of the double block valves are leaking. Note: These gauges will have pressure on them after AMS injection. d. All spare nitrogen cylinders in the racks should be full, i.e., cylinder seals are intact. The above items are vital to the proper operation of the emergency kill system. If any of these conditions are not met, they should be immediately corrected. 3* Other items which should be checked on a routine basis are: a. The automatic AMS injection line reactor nozzles should be checked for plugging. This can be done while the reactor is being rinsed. Full port ball valves have been provided on this line so that a rod or long wire brush can be run through the line to knock out plugging. This line should be checked once a week when the system Is being tested. b. The manual AMS injection line reactor nozzles should also be checked for plugging on a weekly basis. This should be done in a manner similar to that used for checking the automatic injection line. A 1-3 VAB.0001146829 Page 15 1-3 A IV. OPERATING PROCEDURES (CONTINUED) C. Testing Procedures 1. The AMS injection system for each reactor will be tested weekly on a schedule set up by the process superintendent. * Each system will be checked for line pluggage and valve operation. The testing procedure is outlined below: a. The A operator should perform a complete visual check of the system to be tested both at grade level and at the reactor top head level. b. He should then contact the lead operator on the radio and confirm that the reactor and Emergency Kill System are ready to be tested. c. He may then manually inject approximately one gallon of AMS to the reactor by opening the manual injec tion valves for approximately two seconds. d. After AMS has been injected manually, the A operator should close the block valve near the hose connec tion and notify the lead operator that the automatic system is ready for testing. The lead operator may then remotely cycle the injection valves using the momentary-contact MANUAL mode of the control valve hand switch. e. During automatic AMS injection testing, the A operator should be checking for proper operation of the system, i.e., control valves, actuators, and solenoids. VAB.0001146830 Page 16 1-3 IV. OPERATING PROCEDURES (CONTINUED) C. Testing Procedures (Continued) f. After automatic injection testing, the A operator should rod out the vertical sections of line at both reactor injection nozzles to confirm the nozzles are not plugged. 3. The following must be done following a test prior to charging the reactor: a. The pot should be refilled with AMS. b. The pot should be pressurized to 300 psig. c. The AMS injection nitrogen cylinder pressure should be checked (above 1200 psig). d. The pressure of the nitrogen cylinder used to supply instrument air to the automatic AMS injection control valves should be checked (above 600 psig). e. The manual block valve at the reactor top head level near the hose connection should be reopened. VAB.0001146831 1-3 Page 17 V.

It is also compatible with stainless steel, aluminum, and galvanized iron. Copper and coppei alloys are not recommended for this service. This product has a fairly low freezing point (about -10F) and low viscosity. Underground storage tanks and lines should be considered, as their use will prevent freezing in winter and keep the product cool in summer. Storage temperature should not exceed 100 E. Storage under a nitrogen blanket is preferred; exclusion of air (oxygen) will reduce the chances of polymerization, peroxide formation, and fire. Piping can be of the materials listed above. A centrifugal pump is suggested for transfer service. 11 reflon" is suitable for gaskets and packing. An inhibitor, para-tertiary butyl catechol (10-20 ppm), is used in alpha-methyl styrene to inhibit polymerization. If storage time is prolonged, the inhibitor concentration should be checked occasionally ami more inhibitor added, if needed. Alpha-Methyl styrene is a toxic chemical; contact with liquid or vapors shou Id be avoided.

The unsa turn tod vinyl group and the aromatic ring can both be hydrogenated under selec tive conditions. haloqenation - Characteristic addition to the vinyl group and substitution on the aromatic ring can occur with halogens such as chlorine or bromine. These exothermic addition reactions generally require catalysts and/or elevated temperatures and are not considered hazardous if properly controlled. However, reaction with chlorine which occurs at ambient tem peratures can be violent in the presence of light. Accidental contact of C-methylstyrene with halogens or halogen-containing compounds must be prevented. Acids - Under special conditions, the aromatic ring may be attacked by concentrated nitric or sulfuric acids. These reactions must be carefully controlled to avoid hazardous consequences. Also, hazardous oxidation may occur by contact with concentrated nitric acid. Methoxvl a tion - ''"(-Methylstyrene can be reacted under special condi - tions with formaldehyde or CO-II2 in the presence of a catalyst to yield an aldehyde or alcohol. This reac tion is considered to be nonhazardous as it is un likely to occur accidentally. The above discussed reactions other than oxidation, halogenation, and polymerization are generally considered to be nonhazardous. However, when conducted in the plant or laboratory, all of the reactions of f X-me thy 1 styrene should be properly controlled to avoid hazardous consequences. vised 3/15/76 If the UCC customer wants to use rubber hoses for unloading tank trucks, the recommended materials are Vi ton A or polyethylene lining! and'steel or 304 SS fittings.

FOR INDUSTRY USE ONLY I OTHER HANDLING AND STORAGE CONDITIONS Store under a nitrogen atmosphere; forms acetophenone, aldehydes, and peroxides if stored under air, Dangerous concentrations of peroxides are not expected to form in-normal storage and handling, but storage under a nitrogen atmosphere is recommended. This chemical floats on water, is resistant to rapid biodegradation, and is highly toxic to aquatic life. Spills should not be flushed to sewers or waterways. The preferred method of disposal is to dilute with a non reactive solvent or fuel stream and incinerate. Ground areas can be covered with sand or sawdust after most of the spilled material lias been removed. Absorbing materials, after use on small spills, should be disposed of in an approved chemical landfill or by burning. CAUTION: Do not use clays, micas, or acidic materials which might catalyze polymerization, as absorbents. Personnel engaged in disposal work should avoid contact of wastes by wearing proper protective clothing. VAB.0001146840 1-3 VAB.0QQ11168411 % w r* .h I --------------------------- / U: *11- >-- 1^.
