Document Type and Number:
WIPO Patent Application WO/2011/134847
Kind Code:
A3
Abstract:
A process for producing power from a sour gas comprising H2S, the process comprising the steps of: (a) providing a sour gas stream comprising natural gas and H2S to an acid gas removal unit, resulting in a cleaned natural gas and a acid gas comprising H2S; (b) combusting the cleaned natural gas stream with an oxygen containing gas in a gas turbine to produce power and a hot flue gas; (c) sending the hot flue gas to a first heat recovery steam generator to generate steam and a clean flue gas; (d) combusting at least part of the H2S in the acid gas comprising H2S in the presence of an oxygen containing gas to obtain a hot gas effluent comprising S02; (e) sending the hot gas effluent comprising S02 to a second heat recovery steam generator to generate steam and a cooled gas effluent comprising S02; (f) leading the cooled gas effluent comprising S02 to a sulfuric acid unit to produce sulfuric acid, steam and a cleaned flue gas stream.
