Claim:
A process for the dehydration of a gaseous effluent that comprises: a) A stage for absorption of H 2 O by contact of the gas that is to be treated and heated regenerated solvent obtained from stage e), producing a dehydrated gas effluent and a liquid solvent effluent charged with H 2 O and absorbed gas, b) A stage for cooling said solvent charged with H 2 O at ambient temperature, c) A stage for separation by segregation during which the H 2 O and the solvent are separated at ambient temperature, d) A stage in which the regenerated solvent obtained at the end of stage c) is heated, e) A stage in which the regenerated and heated solvent obtained at the end of stage d) is recycled to the absorption stage a), in which said solvent is any of diethyl phthalate of chemical formula C 12 H 14 O 4 , diethyl sebacate of chemical formula C 14 H 26 O 4 , diethyl azelate of chemical formula C 13 H 24 O 4 , and diethyl suberate of chemical formula C 72 H 22 O 4 .
