This Executive Summary covers the conceptual, or study design of an Exxon Donor Solvent (EDS) Coal Liquefaction Commercial Plant feeding Illinois No. 6 bituminous coal. 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 solvent at about 840/sup 0/F and 2000 psi. The study design explores the technical and economic issues which might be faced if an EDS commercial-size plant were to be designed on Illinois coal. It depicts the state of EDS technology in 1978, after approximately ten years of development work, as this technology might be applied in a commercial-size facility. Potential process improvements conceived after the design basis was set in 1978, such as liquefaction bottoms recycle and direct combustion of liquefaction bottoms, are not reflected here. Entitled the Study Design Update (SDU), this conceptual design is a complete update of an earlier, less extensive study design prepared by the EDS Project in 1975/1976. The SDU was started in 1977, and technical work was completed in 1979; about 245 engineer-months of effort were expended. The objectives of the SDU were to identify the technical issues facing a potential commercial-size EDS plant design, to provide a reliable basis for estimating the cost of EDS products, and to furnish research guidance to the EDS Project. Also, the SDU was to provide a firm starting point for initial commercialization studies of a future pioneer liquefaction plant. These objectives were achieved.
