Abstract

A continuous and regenerative process for removal and destruction of VOC from effluents is disclosed. The process employs two fixed bed reactors in series filled with adsorbent/catalyst. The VOC containing effluent is passed over the first reactor for adsorbing VOC, while the second reactor, which is loaded with VOC from the previous cycle is regenerated with part of the treated gas made up with an appropriate amount of air. Just before the VOC breakthrough occurs at the first reactor, the roles of the two reactors are switched. The process is characterized by simple design, high VOC removal efficiency, no external heat requirement and low operation cost.
