Process for the recovery of one or more components of a raw gas, absorbed by the scrubbing liquid during a physical gas scrubbing step, by expanding the laden scrubbing liquid, characterized in that the expanded, laden scrubbing liquid is stripped, before its final regeneration, with a gas consisting exclusively of one or more components of the raw gas and essentially free of the components to be recovered and to be scrubbed out.
