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.
Claims11
A method or removing an acid gas from a gas system, comprising the step of:
- (a) exposing an acid gas sorbent comprising an aminated polymer to the gas system under conditions suitable to reactively complex the acid gas with said aminated polymer, said aminated polymer having a molecular weight greater than or equal to approximately 5000, said aminated polymer comprising covalently attached amino functional groups suitable to complex the acid gas.
