    摘要: The present invention relates to a new alkaline absorbent solution that reduces the H.sub.2 S content in a treated gas to below 10 vppm. The absorbent solution contains two severely-hindered amines, such as bis(tertiarybutylaminoethoxy)-ethane (BTEE) and ethoxyethoxyethanol-tertiarybutylamine (EEETB), a severely hindered amine salt, and/or a severely hindered aminoacid. This invention also describes a process for the removal of H.sub.2 S from fluid mixtures using this absorbent solution to produce a very low level of H.sub.2 S in the treated fluid. The process is also suitable for the selective removal of H.sub.2 S from fluid mixtures comprising H.sub.2 S and CO.sub.2.

    摘要: A novel class of diaminoether compounds wherein one amino group thereof is a tertiary amine in N-heterocyclic form and the other amino group is a severely sterically hindered secondary amino group may be prepared by a three-step process and are useful in the selective removal of H.sub.2 S from mixtures containing H.sub.2 S and CO.sub.2.
