Purpose of Design The purpose of this design is to provide the VCM railcar unloading area with an additional gas monitoring system to detect serious VCM releases. Presently, there are six fixed point monitor locations that are tied into one of the plant's Honeywell GC's. These monitor locations are listed below: 1. Sphere (grade level). 2. Compressor shed (grade level). 3. Between railcar unloading stations number 1 and 6 (Top of railcar level). 4. Between railcar unloading stations number 2 and 7 (Top of railcar level). 5. Between railcar unloading stations number 3 and 8 (Top of railcar level). 6. Between railcar unloading stations number 4 and 9 (Top of railcar level). These existing monitors do not provide immediate response and are not distributed throughout the entire VCM tank farm area. Also, since this area is not monitored by plant personnel the majority of the time and since it has the potential for a serious release, additional protec tion is needed. In addition to the gas monitoring system, this design will provide a pressurization blower for the fire pump houses near the VCM tank farm. The purpose of this blower is to prevent VCM from entering the build ings in the event of a serious VCM leak. This design will also provide for Item 84-6 of the Underwriter's In surance Company recommendations. This item recommended installing vapor detectors for the sphere's VCM transfer pumps to the old and new module. ABD00204611 VCM GAS MONITORING SYSTEM VCM TANK FARM AREA ABERDEEN CHEMICAL PLANT Process Description This design will provide for the installation of ten VCM gas sen sors, AT-101 through AT-110, in the VCM tank farm area (see P&I dia gram for locations). These sensors will be tied into dual channel combustible gas monitors, AI-121 through 125. Each monitor will accept signals from two sensors and display the higher of the two readings. The monitors will indicate the percent of the lower ex plosive limit (LEL) of VCM gas in the air. The monitors will be tied into alarms in the vinyl control room. The first alarm will be set at 25% LEL and the second alarm will be set at 45% LEL. Should any of the monitors indicate a low level (25% LEL) of VCM gas in the air, the panel operator will notify the yard operator of the situation. If the monitors indicate a high level (45% LEL) of VCM gas in the air, the panel operator will then notify the yard operator to shut down any transfer or unloading equipment that is being used. When this equipment is off, the panel operator will isolate the sphere by pushing the sphere control valve override switch. This switch will close the following valves: (1) The valve on the vapor line to/from the compressors. (2) The valve on the liquid line from the compressors. (3) The valve on the liquid line to the VCM transfer pumps. (4) The valve on the liquid recirculation line from the VCM transfer pumps. The monitors will be equipped with relay connections to tie into the existing sphere isolation control valve override switch. However, the relay connection will not be tied into this switch until the REMOTE OPERATING VALVES project is installed. When this project is installed, additional equipment and valves will be shut off by the sphere isolation control valve override switch. This includes: (1) The valve on the liquid return line from the VCM vapor line knockout pot. (2) The five VCM compressors in the VCM tank farm. (3) The two VCM transfer pumps. After installation of this project, the relay connections from the gas monitors will be tred into the sphere control valve override switch. Should the monitors indicate a high level (45% LEL) of VCM gas in the air, the sphere control valve override switch will automatically shut off all the valves ahd equipment mentioned above. When the isolation switch is used, it will override the motor con trols and shut down the units should they be in service. ABD00204612 % VCM GAS MONITORING SYSTEM VCM TANK FARM AREA ABERDEEN CHEMICAL PLANT II. Process Description - Continued In addition to the vapor monitors, a pressurization blower, F-150, will be installed for the fire pump houses. This blower will pro vide air to pressurize fire pump houses #1, //2, //3, and #4. Pressurizing the fire pump houses will prevent any VCM from entering the buildings in the event of a serious VCM leak. The blower's controls will be tied into the 25% LEL alarm in the con trol room so that when this alarm goes off, the blower starts. The blower was sized to maintain a 0.25 inch of water pressure in the buildings while providing enough air to the diesel engines for combustion. This blower will be equipped with an extended inlet stack to provide VCM free air in the event of a serious release. ABD00204613 VCM GAS MONITORING SYSTEM VCM TANK FARM AREA ABERDEEN CHEMICAL PLANT III.

The system consists of two remote sensing assemblies and a solid-state controller. For safety, reliability, and ease of calibration, sensor outputs are not summed. Each channel is completely independent and has its own constant current sensor drive circuit. Sensors are available to meet various service requirements for most gases. The Model 580 independently moni tors two locations. The controller automati cally displays the higher reading channel on an analog meter, scaled from 0-100% LEKLower Explosive Limit). Manual over ride switching permits readout of the low channel at any time. Low and high alarm set-points are common to both channels. Calibration of each channel is done inde pendently, and an alarm override switch disables the alarms during the calibration mode. A 45 second time delay also disables the alarms on start-up. Customers may select from a wide variety of relay options, such as normally energized or de-energized high and low alarms, and latching or non-latching high and low alarms. The malfunction relay circuitry is normally energized and monitors both channels.

Each sensor must undergo extensive burn-in and rigid quality control procedures before shipment. The sensors consist of two catalytic bead elements in a balanced Wheatstone bridge circuit (See Principle of Operation). These low temperature catalytic bead sensing elements require minimal sensor excitation current, greatly increasing sensor life. Principle of Operation A catalytically treated ceramic active bead and a passivated ceramic reference bead form two legs of a Wheatstone bridge circuit. Combustible gases diffuse through a flame arrestor and oxidize on the catalvticallv treated active bead, causing an increase in its temperature and electrical resistance. This results in an unbalancing of the Wheatstone bridge circuit. The reference bead, inert to combustible gases, compen sates for ambient temperature, humidity and pressure changes The difference m resistance of the active and reference beads is converted into a sensor signal which is amplified in the controller, sent to the indicator and alarm circuits, and displaved on an analog meter. The meter is scaled in percent of the Lower Explosive Limit (% LEL). In the Model 580 the two sensor inputs are continuously compared, the higher signal being displayed on the meter. Two adjustable electronic alarm circuits may be field-set for any alarm level up to 100% LEL. The low alarm signal indicates potentially hazardous gas accumu lations at low concentrations, allowing time for corrective action. The high alarm signal indicates immediate danger. A flashing malfunction LED will indicate low input power, sensor removal or damage, "CAL" mode, severed cable or current failure Two LED channel indicators are provided to indicate the higher channel. A variety of alarm relav options provides contacts for high, low and malfunction alarms to be wired to auxiliary lamps, horns, fans or shut-down equipment ABD00204618 **** % LEI Meter Analog output meter with linear scale calibrated in the percent of Lower Explosive Limtt(% LEU Recened Toggle Switch Used for normal operation or calibration When in the "CAL" mode high and low alarms are disabled.

Calibration is accom plished bv adjusting the meter to zero and exposing one of the two sensors to a known concentration calibration gas and adjusting the meter with the span pot to indicate the concentration. The alarm adjustments are located on the side of the controller to prevent tampering. Relay Options The versatility of the Model 580 is enhanced bv the availability of different relay operat ing modes for specific user requirements.

Purchase and install ten gas sensors, AT-101 through AT-110, in the vinyl tank farm area (see P&I diagram for exact location). These sensors should be installed 2-3 feet from grade level. 2. Purchase and install five gas monitors, AI-121 through AI-125, in the emergency generator building located west of the control room. Tie in the following gas sensors to the corresponding gas monitor: AT-101 & AT-102 AT-103 & AT-104 AT-105 & AT-106 AT-107 & AT-108 AT-109 & AT-110 to AI-121 to AI-122 to AI-123 to AI-124 to AI-125 3. Tie in the five gas monitors to two existing alarms located on the incinerator alarm annunciator panel. These alarms will be used to warn operations of any high readings of VCM from the five gas monitors. These alarms are to be labeled TANK FARM HYDROCARBONS ABOVE 25% LEL and TANK FARM HYDROCARBONS ABOVE 45% LEL. 4. Purchase and install a pressurization blower, F-150, at grade level near fire pump houses //l, #2, #3, and //4. Provide a 20 ft. stack for the inlet of the blower with a Bird screen and provide ducting, 8-AV-001, to fire pump houses. 5. Install HAND/OFF/AUTO switch, HS-130, for pressurization blower, F-150, and tie in this switch with the 25% LEL alarm in the control room so that when this alarm goes off, the blower starts.
