Exhaust scrubbers are air pollution control devices used in a wide variety of industrial applications. Reactor, sterilizer, and storage tank venting are common examples of processes requiring exhaust scrubbers. We offer complete exhaust scrubber packages, including instrumentation and controls, skid-mounting of equipment, installation and start-up. AAT, Inc. designs with many different scrubber types, including packed columns, tray columns, spray towers, and ejector-venturis.

Gaseous pollutants exhausted may include chlorine (Cl2), fluorine (F2), ammonia (NH3), hydrogen cyanide (HCN), hydrogen fluoride (HF), methyl trichlorosilane (MTS), ethylene oxide (EtO), or hydrogen chloride (HCl).

Reactors and sterilizers are exhausted using vacuum pumps, and storage tanks are exhausted by virtue of infilling liquid displacing the vapor space volume in the tank. The exhaust vent gas is then routed to the scrubber. In some instances, the vent gas may be diluted with ambient air to lower the concentration of pollutant and provide evaporative cooling of any significant heat of reaction occurring within the scrubber.
