Impregnated activated carbon pellet are used for the removal and containment of hydrogen sulphide, organic mercaptans (thiols) and certain organic sulphides from air. The granular carbon is installed in the fixed bed allowing the odour to pass through the bed. Compounds required to be removed are retained on the activated carbon.
The activated carbon can be used till its exhaustion. It can be normally reactivated or replaced with the new carbon.
