Sulfur Removal

← Previous | Next →

SO2 emissions from IGCC systems are controlled by removing sulfur species from the syngas prior to combustion in the gas turbine. The syngas is assumed to be scrubbed of particulates prior to entering the sulfur removal system and is further cooled to 101°F prior to entering the sulfur removal unit. H2S and COS are removed from the syngas in the sulfur removal unit and sent to a Claus plant and a Beavon-Stretford tail gas treatment unit for sulfur recovery. The sulfur recovered can be sold as a by-product and credited to the sulfur removal technology area.
