About this courseGas absorbers are used extensively in industry for separation and purification of gas streams, as product recovery devices, and as pollution control devices. This course focuses on the application of absorption for pollution control on gas streams with typical pollutant concentrations ranging from 250 to 10,000 ppmv. Gas absorbers are most widely used to remove water soluble inorganic contaminants from air streams.
Absorption is a process where one or more soluble components of a gas mixture are dissolved in a liquid (i.e., a solvent). The absorption process can be categorized as physical or chemical. Physical absorption occurs when the absorbed compound dissolves in the solvent; chemical absorption occurs when the absorbed compound and the solvent react. Liquids commonly used as solvents include water, mineral oils, nonvolatile hydrocarbon oils, and aqueous solutions.
