Title: 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 at least one purification unit (12) and at least one regeneration unit (40) wherein condensed water (72) from the regeneration unit is combined with the regenerated lean hybrid solvent (55) prior to reuse in the purification unit and none of the condensed water is recycled into the regeneration unit.
