초록

Improved processes for treating gas streams containing hydrogen sulfide and carbon dioxide, particularly gas streams from fossil fuel gasification processes. The processes rely on the availability of a membrane that maintains high hydrogen sulfide/methane selectivity and adequate hydrogen sulfide/carbon dioxide selectivity when measured with multicomponent gas mixtures at high pressure. The processes have three steps: an acid gas removal step, to remove both hydrogen sulfide and carbon dioxide from the primary gas stream; a membrane fractionation step, t...

청구항

A process for treating a gas stream from a fossil fuel gasification process, said gas stream comprising hydrogen sulfide and carbon dioxide, and said process comprising: (a) carrying out an acid gas removal step on said gas stream from said fossil fuel gasification process, thereby generating an acid gas stream enriched in said hydrogen sulfide and said carbon dioxide compared with said gas stream; (b) carrying out a membrane fractionation step, comprising: (i) passing said acid gas stream across the feed side of a fractionation membrane having a feed si...
