FILTER DESIGNS FOR ADSORPTION SYSTEMS

摘要

Adsorption is a method used to separate some contaminant species from a mixture of gases or liquids according to the species' molecular characteristics and affinity for an adsorbent material. Adsorbent materials are usually very porous materials chosen because of their large specific surface areas (e.g. silica gel, activated carbon, zeolite). Industrial adsorption systems basically consist of adsorption vessels filled with specific adsorbent materials chosen appropriately to remove contaminants from liquid or gaseous mixtures. Gaseous or liquid mixture passes through the adsorbent material and contaminant species are adsorbed on surface of the adsorbent material.
