The BGL gasifier is supplied with steam, oxygen, limestone flux, and a coal and municipal waste blend. During gasification, the oxygen and steam react with the coal and limestone flux to produce a raw coal-derived fuel gas rich in hydrogen and carbon monoxide. Raw fuel gas exiting the gasifier is washed and cooled. Hydrogen sulfide and other sulfur compounds are removed.
Elemental sulfur is reclaimed and sold as a by-product.
Tars, oils, and dust are recycled to the gasifier. The resulting clean, medium-Btu fuel gas fires a gas turbine. The MCFC is composed of a molten carbonate electrolyte sandwiched between porous anode and cathode plates. Chemical reactions produce direct electric current, which is converted to alternating power in an inverter. The new project site to be provided by Ameren was at their Venice Station Plant in Venice, Illinois, or near East St. Louis, Illinois.
