Water-Gas Shift (WGS) Tests to Reduce Steam Use
Performer: Southern Company Services, Inc.
Project No: NT0000749
The National Carbon Capture Center is testing commercial water-gas shift (WGS) catalysts from multiple vendors in support of developing WGS reactor systems which will reduce the cost of carbon dioxide (CO2) capture from the production of syngas using coal. These tests have revealed that steam-to-carbon monoxide (CO) ratios can be reduced, resulting in a substantial increase in the net power output and significantly reducing the cost of electricity from an integrated gasification combined cycle (IGCC) plant with CO2 capture. Several commercially available WGS catalysts have been tested, and the results are being provided to the manufacturers to aid them in specifying future WGS systems for IGCC plants incorporating CO2 capture.
