TSA-CatOx for Air Purification and Purge Effluent Detoxification.

Abstract

The removal of toxic chemical vapors from air and the subsequent treatment of those chemicals is an ever-growing environmental problem. A unique system has been developed which is capable of removing toxic chemical vapors from air and detoxifying these chemical vapors, in situ. Temperature Swing Adsorption (TSA) is used to continuously remove the toxic constituents from the incoming air stream using a two-bed cyclic operation. During the desorption (purge) step in the TSA cycle, a hot, concentrated effluent is generated which is fed to a catalyst reactor to decompose the toxic vapors. The design and operation of the TSA makes the system unique and is the focus of this work. During the purge step, energy is introduced into the system by heating the adsorbent direetly.
