Abstract: Method which includes passing a gas stream containing carbon dioxide, hydrogen sulfide, sulfur dioxide, mercaptans and other acid gases through an aqueous alkanolamine solution to remove the carbon dioxide, hydrogen sulfide, sulfur dioxide, mercaptans, etc., from the gaseous stream. Heat-stable alkanolamine salts form in the aqueous alkanolamine solution due to the acid contaminants (other than hydrogen sulfide or carbon dioxide) removed from the gas stream. A base is added to the aqueous alkanolamine solution to convert all or part of the heat-stable alkanolamine salts into alkanolamine and simple salts. The base-treated aqueous alkanolamine solution is electrodialyzed in an electrodialysis cell containing ion exchange membranes. The purified aqueous alkanolamine solution can be used again to remove carbon dioxide, etc., from the gas stream.
