EDS Coal Liquefaction Process Development: Phase V. EDS Wyoming Coal Bottoms Recycle Study Design Addendum

摘要

This report documents the results of engineering activities which evaluated the design requirements for a commercial-scale EDS coal liquefaction plant located in Wyoming. The work modified, in addendum format, work previously completed regarding an EDS Wyoming Coal Bottoms Recycle Study Design. The modifications reflected results of recent engineering evaluations and learnings accrued from ECLP operations. As an addendum, this work builds on results of the previously reported study design work and this document should be used in combination with Interim Reports previously documented for the EDS Wyoming Coal Bottoms Recycle Study Design. These include, Onsite Design Basis (FE-2893-84), Offsite Design Basis (FE-2893-87), Onsite Design (FE-2893-104), Offsite Design (FE-2893-105), and Main Report (FE-2893-108). This report, abbreviated as the WYOBR Addendum, focuses its attentions on modifications made to the EDS Wyoming Coal Bottoms Recycle Study Design, referred to as the Base design. 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 approximately 840 exp 0 F and 2500 psi. The WYOBR Addendum explores the technical and economic issues which might be faced if an EDS commercial-size plant were to be designed for Wyoming coal. It depicts the state of EDS technology in 1983, after approximately 15 years of development work which includes nearly two years of experience operating the large-scale pilot plant, ECLP. The WYOBR Addendum utilizes a plant configuration in which the majority of the net solidified vacuum bottoms are used to provide plant H sub 2 . (ERA citation 09:011404)
