AIR SCRUBBER SYSTEM

THE APPLICATION: 2,000 to 20,000 PPM hydrogen sulfide was released to a utility flare and to the atmosphere. Nuisance and potential health problems within local community. 100% saturated airstream, no water or sewer available.

THE DESIGN: 88,000 lbs. Sulfatreat iron oxide filter media installed within an ASME certified steel vessel. Included self regulating heat tracing, tank insulation, high pressure blower, utility flare, piping, valves and controls.

THE IMPLEMENTATION: Aquest Corporation, in conjunction with Tech Environmental, Waltham, MA, provided system design, engineering fabrication, installation and start-up commissioning. Aquest fabricated the scrubber vessel, OSHA caged ladder and service platform along with the installation of self regulating heat tracing to support severe winter operations. The design accommodated cost effective service elements including caged service ladder, service platform, top and bottom access hatches and filter/ air testing ports.

THE RESULTS: The H2S scrubber is providing 99+% removal efficiency in response to a varying load of hydrogen sulfide conditions. The system has exceeded all regulatory requirements over the past eight month period. Aquest maintains a “turn-key” field service solution whenever filter media requires replacement. This includes removal of spent media, replacement of inlet filters, installation of new media, media disposal and system start-up. Inlet and outlet H2S conditions are monitored daily and system performance is recorded for electronic communications to regulatory agencies.
