1. 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.

Abstract
Aminated polymers capable of reversibly complexing carbon dioxide and other acid gases including CO2, SO2, NOx and H2 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.
