Presently, there are six fixed point monitor locations for VCM that are tied into one of the plant's Honey well GC's. These monitor locations are listed below: Sphere (grade level). Compressor shed (grade level). Between railcar unloading stations number 1 and 6 (Top of railcar level). Between railcar unloading stations number 2 and 7 (Top of railcar level). Between railcar unloading stations number 3 and 8 (Top of railcar level). 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. The propane storage area, located east of the boiler house, is not equipped with any gas detection instrumentation. Since these areas are not monitored by plant personnel the majority of the time, and since they have the potential for a serious release, additional protection is needed. In addition to the gas monitoring system, this design will provide a pressurization blower and air heater for the fire pump houses near the VCM tank farm. The purpose of this blower is to prevent VCM from entering the buildings in the event of a serious VCM leak.

Process Description A. VCM Tank Farm This design will provide for the installation of eight VCM gas sensors, AT-101 through AT-108, in the VCM tank farm area (see P&I diagram for locations). These sensors will be tied into dual channel combustible gas monitors, AI-121 through 124. 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 explosive 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 10% LEL and the second alarm will be set at 30% LEL. Should any of the monitors indicate a low level (10% LEL) of VCM gas in the air, the panel operator will notify the vinyl shift supervisor and the yard operator of the situation. If the monitors indicate a high level (30% LEL) of VCM gas in the air, the panel operator will Isolate the sphere by pushing the sphere control valve override switch. This switch closes 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 pump s. (4) The valve on the liquid recirculation line from the VCM transfer pumps. In addition to the vapor monitors, a pressurization blower, F-150, will be installed for the fire pump houses. This blower will provide 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 will run continuously to avoid dependence on an automatic control scheme that could malfunction during an emergency. 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 relase. An electric air heater, HC-100 will be located in the discharge duct of the blower to maintain the pressurization air temperature at 50F year-round. ' ' i 'T'- n ?n > i: 1111 *.

Boiler Propane Storage The boiler propane storage area will be equipped with propane gas sensors AT-109 through AT-112 (see P&I diagram for locations). These sensors will be tied into dual channel combustible gas monitors, AT-125 and AI-126. 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 explosive limit (LEL) of npronpane gas in the air. The monitors will be tied into alarms in both the boiler control room and the vinyl control room. The alarms will be set at 30% LEL. Should any of the monitors indicate a propane gas release, the boiler operator and vinyl personnel will be notified by the alarms so that appropriate action can be taken. 4 I! i- i'i I ' : . . . ; r' I'-I* I- *!- J . !

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% LEL (Lower 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 catalyti cally 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 in 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 displayed 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 to100% 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 relay options provides contacts for high, low and malfunction alarms to be wired to auxiliary lamps, horns, fans or shut-down equipment.

Height T f178 mm) Width 2" (51 mm) Depth Tl.5" (292 mm) Calibration By placing the recessed toggle switch on the front panel to the calibration mode, the high and low alarm relays are held in standby condition and the "MALF" LED flashes. Zero and span pots are accessible from the front panel. Calibration is accom plished by 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 r oncentration. The alarm adjustments are located on the side of the controller to prevent tampering Relay Options The versatility of the Model 580 is enhanced by the availability of different relay operat ing modes for specific user requirements.
