ConocoPhillips. CB&I currently licenses this process technology under the name E-GAS™. The Wabash River IGCC Power Plant is designed to use a variety of local coals, including high-sulfur Midwestern bituminous coals such as Illinois No. 6. In addition, petroleum coke and blends of coal and coke are consumed, in the range of about 2,500 TPD to generate about 262 MWe net output of electricity. Plant design was conducted with the goal of outperforming the Clean Air Act (CAA) emission standards, which limit sulfur dioxide (SO2) at 1.2 lb/million Btu of fuel input and NOx at 0.15 lb/million Btu. Demonstrated emissions are far better than these targets. Despite power generation at the Wabash River complex being almost three times that of the original unit, the total emissions are a fraction of the pre-powering values as a result of the IGCC system. Particulate emissions are negligible. Tampa Electric IGCC Bituminous coal gasification to produce electricity Construction began on this IGCC unit at Tampa Electric Company's Polk Power Station (Polk County, Florida) in October 1994, followed by operational startup in September 1996. The project ran for four years as a demonstration, and continues to operate as a power production facility for Tampa Electric. The plant uses GE Energy's (formerly owned by Texaco), entrained-flow, oxygen-blown gasifier to produce syngas from coal or petroleum coke which feeds a combined-cycle turbine system to produce electricity. The IGCC unit consumes 2,200 TPD of bituminous coal, producing 260 MW of electricity. The following table quantifies the emissions from the Polk Power Station, with comparison to emissions associated with conventional technologies for electricity generation from coal. Typical of electricity generation based on coal gasification with combined cycle generation, emissions of pollutants are far lower than those of conventional technologies. For example, notwithstanding the IGCC unit is fueled by high-sulfur coal and/or petroleum coke, sulfur emissions are very low as a benefit of the MDEA amine gas treating system that removes H2S from the syngas fueling the combustion turbine. Duke Energy Edwardsport IGCC Project Bituminous coal gasification to produce electricity Duke Energy began construction on an IGCC plant in Edwardsport, Indiana in 2008, which began commercial operations in June 2013. The IGCC-based unit at Edwardsport will consume 1.7-1.9 million tons of coal per year to generate 618 MW of base-load electricity. It uses GE gasification technology, GE 7FB combustion turbines, and a GE steam turbine. The IGCC plant replaces a
