Products» Odor Control Systems»Horizontal Chemical Scrubbers(HCS) Horizontal scrubbers have been utilized for more than 40 years to offer a low height configuration for bringing gaseous  contaminant into an intimate contact with a chemical solution. The air moves horizontally through the scrubber  vessel and the chemical solution is flowing  downward through a packing media which provides  an optimum contact media for the transfer of the  pollutants from the gaseous phase into the liquid  phase. The liquid solution contains a dissolved chemical that for most application reacts spontaneously with the gas while is  being dissolved into the liquid phase. For instance, if the pollutant gas is acidic then a basic solution is suitable or if a  basic gas is present then an acidic solution will be effective.  A recirculating liquid system is common for supplying a constant flow of liquid feed at top of the tower. Peripheral  control instruments and control facilitate an automatic control of the scrubber operation. The gaseous phase is either  pushed or pulled through the packing media by a fan.   Copyright © Amerair International 2008 Air Pollution Control & Monitoring
