The opposite operation, known as stripping, involves the transfer of the contaminant from the liquid to the gas phase and is important in water pollution control applications. Absorption occurs into liquid droplets dispersed in the gas stream, sheets of liquid covering packing material, or jets of liquid within the vessel. The liquid surface area available for mass transfer and the time available for diffusion of the gaseous molecules into the liquid are important factors affecting performance. Absorption can be divided into two broad classifications: straight dissolution of absorbate (contaminant gas) into absorbent (liquid), and dissolution accompanied by irreversible chemical reaction.Absorbers in air pollution control applications use aqueous scrubbing liquids to remove gases and vapors. Absorber design has benefited substantially from the extensive development of these types of systems for non-pollution-control process applications and is, therefore, a relatively mature technical field. The use of absorbers has increased since 1990 because of increased concerns about gaseous contaminants, which are classified as air toxic or volatile organic compounds (VOCs). In addition to stand-alone systems, absorbers are frequently used downstream of thermal and catalytic incinerators to remove acid gases generated from the combustion of sulfur-containing and/or halogenated compounds present in the incinerator feed.Column Performances using Composite Materials
