' . Oxidizer Chamber. Tae Oxidizer Chamber is constructed of 3/16 inch carbon steel and lined with a 4 inch ceramic fiber high temperature lining that provides a safe cold ' face temperature while operating at 650°F to 1150° F on the hot face. The oxidizer chamber also has an integral catalytic cell shelf and catalytic cell access door for easy maintenance of the catalytic cell. ' Electric Elements: A custom made Electric Element Plug is installed m the oxidizer chamber Thus provides the necessary heat for the pre-heating of the incornmg vapors tThe operating range for the elements is 600'F to 1000°F o Heat Exchanger: The Heat Exchanger is designed to utilize the catalyst exhaust to ' pre-heat the incoming vapors It is designed with tube bundles that the vapors travel through while the hot exhaust passes around the outside. This is made of a 304 stainless steel material and a 3/8 inch thick carbon steel front--cover with insulation material m Control Panel: The Control Panel contains a main discomiect, on/off switches, lights, controllers, chart recorders, fuses, motor starters, relays and wiring. The panel is a NEMA 4 type for outdoor use and is 48 inches tall x 36 inches wide x 12 inches deep. Valving. The Entrainment Separator carnes equipped with two butterfly valves that are actuated by a drive motor One is a Process Isolation Valve that is provided to isolate the vapors during start-up, when an alarms occurs or when the oxidizer is not at temperature The other is a Dilution Valve that continually modulates and maintains the catalyst outlet temperature at a pre-set level. o Auto Drain Pump: A Liquid Pump is provided to remove the water accumulated in the entrainment separator The pump is activated when the water reaches the high liquid level switch and runs for one minute The pump transfers the water to a + receptacle provided by the client at the site o Liquid Level Switches. Liquid Level Switches are provided on the entrairiiment separator site glass A High Liquid Level Switch activates the hquid transfer pump ' when it is triggered The Mgli/High Liquid Level Switch Alarm 1) turns the entire system off when the switch is actuated. Process Air Pressure Switch: The process line utilizes an Air Pressure Switch to monitor air pressure in the system. If airflow decreases or stops, the Air Pressure Switch Alarm 2 will shut down the system. a Flow Transmitter: The Flow Transmitter receives a high and low air pressure signal from the orifice plate in the process line and transmits a signal to the chart recorder ' The chart recorder records the volumetric flow rate passing through the oxidizer 1
