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 tl^e 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 fo`lowing 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 clo?:e and regular check on equipment. A. Knowing how tc spot malfunctions and correct them. 5. Keeping his area of responsibility safe and clean. 6. Keeping complete and accurate records. C. Process Information The polymeriza13or reaction of VCM to form PVC gives off heat and accelerates a? temperature increases. As the temperature increases, the reactor pressure also increases. It is there fore necessary -o "emove the heat of reaction with cooling VAB.0001221269 Page 2 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 renoval. If reactor coolinc 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 coulc increase until the rupture disk/safety valve assemblies would \,ent the reactor contents to the atmosphere. The new Emergency Kill System provides the capability of in jecting up to 25 cal Ions of killing agent into each reactor either remotely from the control room or manually at the re actor top head plctform. 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 acdition to removing heat of reaction. A VAB.0001221270 Page 3 A GENERAL PROCESS DESCRIPTION Refer to the attached PI 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 gajges are provided on each pot in addition to board-mounted low pressure alarms and low level indicators. The A operator should .heck the appropriate injection pot level and pressure bef>re 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 sys :em will be activated from the board to minimize time and maximize mixing. One switch for each reactor operates automatic douule block valves at the reactor top head level. Placing the sw tch in automatic mode opens the valves and allows a low level swi ch in the injection pot to close the valves. Placing the switch in he momentary-contact manual mode also opens the valves but the val'-es close when the switch is released. Each injection pot low 1 eve 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 cooling efficiency. VAB.0001221271 Page A 11 GENERAL PROCESS DESCRIPTION (CONTINUED) Emergency injection Leaders 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 acent 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 he cylinder in use has dropped below 600 psig. A cylinder with less than 600 psig pressure does not contain enough nitrogen to operate he control valves and should be immediately changed out with a full cylinder. A VAB.0001221272 Page 5 A SAFETY The operation of the emergency kill system does not present any extreme 1y 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 safe y hazards and proper handling procedures. The attached vendo literature describes chemical properties and safe handling procedures It should be emphasized that AMS is highly read ive 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 nitrcgen 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 precutions should be taken while working with or near these vessels. The injection pots must be depressurized before the block valves on the pot funnel cr 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 wm ----------------- ---------------- ^ --. . .. _ SIDE OF THE POTS. VAB.0001221273 Page 6 A 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 a^snt is a volatile hydrocarbon, and thus fire and explosions ar* 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 VC.M 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 ma ntained at 300 psig pressure except when re fill i ng. F. Finally, operator1 should keep in mind that this system will be used when the plant is in an upset condition, i.e., power failure, loss of cooling water, reactor runaway, etc. It is VAB.0001221274 Page 7 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 ihis system. A VAB.0001221275 IV. OPERATING PROCEDURES Page 8 A. Injection Procedures 1. The emergency kill system should be activated under the following circumstances: a. Extended loss of cooling water to a reactor in poly mer i zaiion 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 emergen ;y kill system must be activated If the reactor reaches the following pressures for the following products: a. 5305 wi :h CTA 155 psig b. 5305 wi hout CTA 165 psig c. All other products 1kS psig 3. Lead Operator Duties a. The lean operator should remotely Inject AMS into the polymer zing reactors which require killing by placing the appropriate hand switches in the AUTO mode.

The lead operator should then check for confirmation of AMS in ection from the board-mounted low level indicat ing lights, and from the A operator via radio. In jection t me 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 te plugged requiring manual injection. c. After AMS injection, the lead operator should closely monitor tfe 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. e. If excess nitrogen does enter the reactor, the condenser should be vented to the recovery system. 3 A Operator Puties 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 Page 10 OPERATING PROCEDURES (CONTINUED) ^1^--^X---- - , A. Injection Procedures (Continued) 3 A Operator Duties (Continued) means not enough AMS was injected. No level may mean nitrogen las entered the reactor. b. The A operator should also check the pressures 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 inj ection. 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 are closeti. If the valves are open, he should man ually block in the line and inform the lead operator that nitre gen 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 actor. He should open the manual double block injection valves, wait for the injection pot low level indicator light to light, then immediately close the double block valves. The valves should also be immediately closed if the line begins to vibrate from flowing nitrogen. Page 11 A V. 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 ano 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 nay enter the reactor. L f. As soon as possible after injection, the A opera tor shoulc 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 va1ve. 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 irto the funnel on the side of the injection pot. VAB.0001221279 Page 12 OPERATING PROCEDURES .CONTINUED,.! A.

Radio comnunication between the lead operator and the A operator should be maintained. The A operator should inform ths lead operator how the system is operating and what is being done in the field. The lead operator should kesp 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 oroper operating condition. It is the respon sibility of tie 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 1 *vel in the injection pot should be at the full mark, on tie 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. Page 13 A 1 v- OPERATING procedures (continued) B, Routine Operation (Continued) ni nm' \ - ------------- i ~ i ii i 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 leve 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 te checked by the A operator at the beginning of each shift: a. The pressire 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 shou 1 d be 100 ps i g. VAB.0001221281 Page 14 IV. OPERATING PROCEDURES (CONTINUED) - '------------------ -------------------- -- ii Bir--------------- iin i m* . 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.2., 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 th; reactor is being rinsed. Full port ball valves hove been provided on this line so that a rod or long wire brush can be run through the line to knock ou ; plugging. This line should be checked once a week w len the system is being tested. b. The manuul AMS injection line reactor nozzles should also be ;hecked for plugging on a weekly basis. This should bo done in a manner similar to that used for checking the automatic injection line. A VAB.0001221282 Page 15 IV. OPERATING PROCEDURES (CONTINUED) C. Testing Procedures I. 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 shou'd then contact the lead operator on the radio and coniirm that the reactor and Emergency Kill System ere 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 momentar/-contact MANUAL mode of the control valve hand switch. e. During ajtomatic AMS injection testing, the A operator should b; checking for proper operation of the system, i.e., coitrol valves, actuators, and solenoids. A VAB.0001221283 Page 16 A V. 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 mast be done following a test prior to charging the reactor: a. The pot shoald be refilled with AMS. b. The pot shoiid 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 alock valve at the reactor top head level near the hose connection should be reopened.
