EDS Wyoming Coal Bottoms Recycle Study Design: Main Report. EDS Coal-Liquefaction Process Development, Phase V. Interim Report

摘要

This is the Main Report for the EDS Wyoming Coal Bottoms Recycle Study Design and includes a summary section describing the process configuration and design and sections describing the Economics, Product Recovery Factor, Material and Energy Balances, and Investment Estimate. This Main Report, in combination with other Interim Reports (Onsite Design Basis: FE-2893-84, Offsite Design basis: FE-2893-87, Onsite Design: FE-2893-104, and Offsite Design: FE-2893-105), covers the conceptual or study design of a commercial Exxon Donor Solvent Coal Liquefaction Plant feeding Wyoming sub-bituminous coal. In addition, process and equipment areas which require additional develoment, as indicated by results of recent engineering evaluations and by learning accrued from ECLP operations, are currently being evaluated as part of an addendum tp this study design. The EDS process directly converts coal to a range of clean hydrocarbon products by contacting the coal with hydrogen in the presence of a hydrogenated solvent at approximately 840 exp 0 F and 2500 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 Wyoming coal. The objectives of the study were to provide an improved base point for initial commercialization studies for a pioneer EDS plant, to provide a bench mark for the cost and economics of an EDS plant feeding Wyoming sub-bituminous coal, to incorporate the latest laboratory and engineering results into a complete commercial plant design, and to identify process and equipment areas requiring additional development. These objectives were achieved. (ERA citation 08:039916)
