catalytic scrubber

Catalytic scrubber is important to remove toxic gases and make the pollutants into simple non-hazardous components. Apzem developed a catalytic dry scrubber for this purpose. The catalytic scrubber works on principle of chemisorption process. Chemisorption is an adsorption process which involves chemical reaction between the toxic pollutants and chemical present on the surface of adsorbents. This type of scrubber consist of catalyst which adsorbs the gaseous pollutants and reacts with them to make into simple components. Unlike normal adsorption dry scrubber, the catalytic scrubber will not be affected by contact time and inlet pollutant concentration. When the catalyst is saturated with pollutants, this can be easily taken back and replace with new catalyst. This type of scrubber is suggested for exhaust with low concentration of toxic gases, because of life time of catalyst. It can also be used for exhaust with high concentration. However, the catalyst will be saturated within a short period of time. It can also be used for emergency applications, where there is higher pollutant contamination risk.
