"Method for treating residue gases proceeding from sulphur removing units and plants for carrying out the said method". ABSTRACT OF THE DISCLOSURE This invention relates to a method for treating residue gases proceeding from units applying the Claus reaction for the removal of sulphur and having been subjected to a conver- sion of the sulphur compounds into sulphuretted hydrogen. This method consists in that, prior to absorption of the sulphuretted hydrogen by a selective solvent in aqueous solu- tion, the gases to be treated are cooled to a temperature so selected as to condense the water contained in the gases to form an aqueous effluent which is thereafter injected into the circuit of the selective solvent.
