This article describes the conceptual, or ''study'' design of an Exxon Donor Solvent (EDS) coal liquefaction commercial plant feeding Illinois No.6 bituminous coal. The study design was executed as a part of the EDS Project, a joint government-industry development effort, to guide engineering and laboratory research activities. The EDS process directly converts coal to a range of clean hydrocarbon products. This is accomplished by contacting the coal with hydrogen in the presence of a hydrogenated donor solvent at about 450/degree/C (840/degree/F) and 13,790 kPa (2,000 psi). The study design explores the technical and economic issues. The detailed analysis of the different modes of operation has indicated the complexity of the fuel balances in meeting plant demands. An EDS plant is highly integrated, because it derives both its fuel gas and hydrogen from the liquefaction residue. Changing the process configuration offers the most promising approach to improved plant thermal efficiency and economics. 3 refs.
