C. greater than 8.6, preferably ranging from 9.3 to about 10.6, and a cumulative -E.sub.s value of at least 1.9 are found to be useful in selective removal of H.sub.2 S from a normally gaseous mixture containing H.sub.2 S and CO.sub.2.

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:
Disclosed is a process for selectively removing one or more acid gases from hydrocarbon feed streams containing the same using hydroxyalkyl pyrrolidones as a physical solvent for each of the acid gases or aqueous mixtures containing the physical solvent. The process may be operated using the generalized flow sheet of a typical industrial acid gas treating plant as shown in FIG. 1.
