Monroe Environmental was contacted to provide an air pollution control solution to purify a nitrogen gas stream for a gulf coast chemical manufacturing plant. The nitrogen gas contained ~12% Para Tertiary Butyl Phenol (PTBP) which was to be scrubbed and recovered from the Naphtha scrubbing solution.
Scope of supply included 304 stainless steel packed tower with integral recirculation reservoir, recirculation pump, recirculation piping and valves, tower packing media, spray nozzles, mist eliminator, scrubber mounted junction box, and explosion proof control panel. The integral liquid reservoir included a baffled separation chamber, armored sight glass, liquid level instrumentation, pressure relief vent, and liquid fill solenoid valve.
The instruments and controls were rated for operation in a Class 1, Div. 2, Group C & D hazardous environment.
The system was rated to treat 180 ACFM @ 250°F.
