Hydrocarbon Research, Inc. (HRI) is conducting a program for the United States Department of Energy (DOE) for evaluation of a ''New Technology'' concept for Catalytic Two-Stage Liquefaction of coal. HRI has demonstrated greatly improved coal liquefaction process performance by Catalytic Two-Stage Liquefaction (CTSL). (Bench-scale screening studies identified an improved set of operating conditions for Illinois No. 6 (Burning Star Mine) coal and a demonstration run (227-20) at these conditions has been completed. Results from this run were used as a basis for this conceptual plant design and economics study.) The purpose of this study is to identify the economic incentive for CTSL over the conventional single-stage H-Coal Process. This information will be used to guide future experiments for further process optimization. Preliminary designs for CTSL (based on Run 227-20) and the H-Coal Process liquefaction sections are developed based on HRI's design experience from the Breckinridge Project and H-Coal Pilot Plant operations at Catlettsburg. Complete conceptual commercial plant designs are developed for grassroots facilities using HRI's Process Planning LP Model. Product costs are calculated and economic sensitivities are analyzed. Results of the economic evaluation show CTSL reduces the product costs by 12% compared to the single-stage H-Coal Process. 140 refs., 9 figs., 55 tabs.
