ABSTRACT:
For regeneration of a loaded scrubbing agent, e.g. a polyethylene glycol ether containing H.sub.2 O and sour gases, the regeneration is conducted in a regeneration column equipped with a bottom heater and an overhead condenser, by stripping with vapor, e.g. stream provided by the heater vaporizing an aqueous condensate. After condensation of the vapor in the condenser, the stripped components are removed and the remaining condensate is recycled to the bottom part of regeneration column to avoid mixing the aqueous condensate with the loaded solvent. The condensate is fed directly into the bottom of the column or is fed into the line between the column and the bottom heater.
