  • Method for compressing gases containing hydrogen sulfide
    Patent number: 9067872
    Abstract: A process for compressing a hydrogen-sulfide-comprising gas stream, which comprises (i) compressing the hydrogen-sulfide-comprising gas stream in a compressor, (ii) flushing the compressor with a mixture comprising dialkyl polysulfides, dialkyl disulfides and at least one amine; a process for producing sulfur compounds, selected from the group consisting of alkylmercaptans, dialkyl disulfides and alkanesulfonic acids, which comprises the conversion of hydrogen-sulfide-comprising gas streams, wherein the hydrogen-sulfide-comprising gas streams are compressed according to the process comprising steps i) and ii); and also the use of a mixture comprising dialkyl polysulfides, dialkyl disulfides and at least one amine for removing sulfur deposits which occur in the compression of hydrogen-sulfide-comprising gas streams.
