Abstract

A process for the purification of a mixture of wet or dry gases containing sulfur dioxide, by selective absorption of the sulfur dioxide present therein, comprising passing a gaseous mixture containing sulfur dioxide in contact with a liquid solvent that It comprises an N-alcohol lactam or cycloalcohyl lactam, separating the sulfur dioxide from the liquid solvent, separating the substantially purified wet or dry gas mixture from the sulfur dioxide and recirculating the solvent for reuse in another absorption.
