Improved efficiency in recovering SO2 from waste gases is obtained in a system where the SO2 is absorbed into a solution which is then distilled. The method of this application entails compressing the steam-SO2 mixture issuing from the still before condensing out the steam, so that the heat from the compressed steam-SO2 mixture may be used in generating the steam for the still, and the condensate may be recycled through the still, preferably after reheating the same.
