Title: ENERGY EFFICIENT PROCESS FOR SEPARATING HYDROGEN SULFIDE FROM GASEOUS MIXTURES USING A HYBRID SOLVENT MIXTURE
Abstract:
Disclosed is a process for regenerating a hybrid solvent used to remove contaminants from a fluid stream and to provide an improved yield of purified fluid. Said process comprises a purification unit (12) and at least one regeneration unit (40) wherein make-up water (72) is added to the regenerated lean hybrid solvent (55) prior to reuse in the first purification unit and no water is recycled into the regeneration unit.
