Industrial CO2 Reduction: Environmental View

Excerpt

Several techniques have been proposed to reduce the emission of CO2 into the Atmosphere. Among these techniques, chemical solvent absorption methods have been extensively studied and are considered as a reliable and relatively competitive method for reducing carbon dioxide emissions from fossil fuel power plants. Aqueous solutions of alkanol amines are widely used in absorption/desorption processes to separate CO2 from gas streams. Aqueous blends of a primary or a secondary amine with a tertiary amine or carbonate have received much attention. Recent works suggest that a small amount of a primary or secondary amine, such as Mono Ethanol Amine, or Di Ethanol Amine can be added to an aqueous Methyl Di Ethanol Amine solution to promote or enhance the absorption rate of CO2 without significantly affecting the steam stripping equipment.
