The present invention integrates a gasification unit (2) into a catalyst/absorber process for removing pollutants from the combustion product of a gas turbine (8). A small slipstream of syngas from the gasification unit (2) is cleaned in an acid gas removal unit (4) to remove hydrogen sulfide. The syngas is then processed in a shift unit (18) where the carbon monoxide and any COS present in the syngas are converted into hydrogen and carbon dioxide. The shifted syngas, still containing trace amounts of hydrogen sulfide, is then processed in a zinc oxide bed (6), where the trace hydrogen sulfide is removed. The resultant stream is hydrogen and carbon dioxide rich, making it ideal for use in regenerating the catalyst/absorber system. |
