One of the primary missions of the Department of Energy's Morgantown Energy Technology Center (METC) is the development of an information and data base on the engineering and environmental aspects of advanced technologies for the conversion of relatively abundant energy sources, such as coal, to clean fuels. Such fuels may be suitable for a number of end uses, including substitute natural gas, fuel gas for use in gas turbines, and others. METC has provided support for the development of a number of synfuels technologies, including the Mountain Fuel Resources (MFR) and Kellogg-Rust/Westinghouse (KRW) gasification technologies, and several raw gas and aqueous waste cleanup technologies. The primary objective of this project was to obtain and evaluate environmental data for advanced synthetic fuel technologies of interest to the Department of Energy as well as associated pollution controls, such as gas cleanup and wastewater treatment technologies.
