ABSTRACT:
A regenerable process for scrubbing SO.sub.2 from effluent gases using an aqueous alkanolamine and the corresponding sulfite as the solvent, such amine having a boiling point below about 250.degree. C. at one atmosphere pressure and wherein the alkanolamine solutions containing heat stable salts (HSS) is regenerated by alkali addition, crystallization and vacuum distillation of the amine.
