Selection of appropriate adsorption technique for recovery of VOCs: an analysis

Realization of the adverse effects of volatile organic compounds (VOCs) in the environment and the consequent enforcement of stringent regulations, accelerated the research and developmental activities across the world for achieving economic solutions. As a result, several advanced concepts of adsorption, a commercialized separation technology, have emerged. The availability of so many options means the industrialists, consultants and researchers experience problems in selecting the appropriate one. The present paper, through analysis of the type and concentration of VOCs, VOCs vs adsorbent suitability, the extent of separation required, and different adsorption techniques based on traditional and new advanced concepts, is an attempt to establish a qualitative guideline for the selection of the appropriate technique for recovery of VOCs.
