A PROCESS FOR PRODUCING A FLUID MIXTURE FREE OF H2S BY THE SELECTIVE ABSORPTION OF H2S FROM A FLUID MIXTURE

摘要

An alkaline absorbent composition comprising a severely hindered amino compound and an amine salt is provided. A process for the removal of H2S from fluid mixtures using this absorbent composition to produce a very low level of H2S in the treated fluid is also provided. The process is also suited for the selective removal of H2S from fluid mixtures comprising H2S and CO2.
