Abstract:
An alkaline absorbent composition comprising a severely hindered amino compound and an amine salt is provided. A process for the removal of H.sub.2 S from fluid mixtures using this absorbent composition to produce a very low level of H.sub.2 S in the treated fluid is also provided. The process is also suited for the selective removal of H.sub.2 S from fluid mixtures comprising H.sub.2 S and CO.sub.2.
