Universal Continuing Decision Process For: GE Energy *
| The GE Energy gasification process was developed by Texaco in the 1950s, and purchased by GE from Chevron-Texaco in 2004. The process uses an entrained flow, refractory-lined gasifier. Coal is fed to the gasifier as coal-water slurry and injected into the top of the gasifier vessel. Syngas and slag flow out the bottom. Three options are available: Quench, Radiant, and Radiant & Convective. GE Energy gasifiers were used in the first IGCC project in the US, the Cool Water Project in southern California, which operated for five years starting in 1984. After the demonstration period, the gasification block was sold, dismantled and moved to Kansas where it became the heart of a petroleum coke-to-ammonia plant. The GE Energy process is used in the Tampa Electric Company’s Polk County IGCC, a 250-MW plant that began operations in 1996. Duke Energy is building a 630-MW IGCC plant at the site of its existing coal and oil fired power plant in Edwardsport, IN, using GE’s gasification technology. It will replace four older generating units totaling 160-MW and is scheduled to come on line in 2012. GE has also been selected to provide gasifiers for ERORA’s Cash Creek IGCC in Owensboro, Kentucky, scheduled for start-up in 2011, AEP’s Mountaineer Plant in West Virginia scheduled to start-up in 2012 and the Tenaska IGCC Plant in Taylorville, Illinois, scheduled for 2014.
