The effort on this contract is 65 percent complete. A screening study has been completed to select the process configuration. The Donor Solvent (CSF) process was established as the core process. The plant has been sized for a coal feed rate of 30,000 tons/day. The plant will produce its own power in a combined cycle plant. A captive underground coal mine is included in the scope of the project. The project employs a processing scheme with pronounced advantages over the design employed at the original OCR pilot plant at Cresap, West Virginia. Although both schemes employ the same extraction technology involving a donor solvent and mild extraction conditions, they are otherwise quite dissimilar. The configurational analysis carried out by Fluor led to: a lower depth of extraction with a more selective usage of hydrogen; gravity settling instead of filtration resulting in a substantial capital cost savings; and production of hydrogen from internally produced char via a thermodynamically efficient gasification technique rather than feeding light hydrocarbons to a steam reformer. Stringent environmental standards have been applied as exemplified by the use of low-S fuel gas for internal requirements rather than high-S coal, char, or heavy hydrocarbon liquid. In view of these and other advantages over the earlier technology practiced at Cresap, this plant has been termed the Advanced Coal Liquefaction Plant. All of the process diagrams to describe this design have been prepared. Seventy-five percent of the mechanical flow sheets have been drawn and reviewed. A plot plan has been developed. Data sheets are being prepared and priced for the major pieces of equipment. The capital cost estimate has been started and will be based on these equipment prices. Work has begun on the computer model to perform these calculations. This contract will be completed in October, 1977.
