Abstract

For regenerating a scrubbing agent loaded with H.sub.2 S and/or COS, as well as optionally with other raw gas components to be recovered, the loaded scrubbing agent is mixed, preferably without prior heating, with an oxidatively acting solvent that is immiscible with the scrubbing agent, and the H.sub.2 S dissolved in the immiscible solvent is converted to elementary sulfur.
