Abstract
Aminated polymers capable of reversibly complexing carbon dioxide and other acid gases including CO.sub.2, SO.sub.2, NO.sub.x and H.sub.2 S, a method of using such polymers and an operational unit including such polymers are disclosed. The polymers incorporate amine group which reversibly complex acid gases. Such polymers provide a significant advantages over presently used sorbents used to remove acid gas.
Claims10
A reaction product from a reaction of an aminated polymer, said animated polymer having a molecular weight greater than or equal to approximately 500, said aminated polymer comprising covalently attached amino functional groups suitable to complex at least one acid gas, said at least one acid gas selected from the group consisting of CO.sub.2, SO.sub.2, H.sub.2 S, NO and NO.sub.2, wherein said at least one acid gas reacts with amino groups of said aminated polymer to remove said at least one acid gas from a gas system.
