Northeast coal utilization program: Phase 2. Final report. [Evaluation of coal liquids as fuels in northeast USA]
This report documents the activities of a group of utilities drawn from the northeastern United States. It relates to the introduction of coal liquefaction as a source of the liquid fuel needed for power generation in the region. Coal liquefaction by hydrogenation using the H-Coal, Exxon Donor Solvent, and SRC-II processes is the focus of general studies related to technology and economics, to commercial project development, and to plant siting. Achievement of significant coal liquefaction capacity in place is recognized to be hindered by technical risk and lack of economic incentive as the nation adjusts to the use of heavy, high sulfur crude oils. Against this background, the concept is developed of a convertible plant capable of functioning in both coal liquefaction and in heavy oil upgrading. Construction of a single train coal liquefaction facility based on purchasing hydrogen and other services from an adjacent oil refinery is also considered as a method of introducing first generation coal liquefaction plants at minimum risk. Studies of process configuration show that least cost coal liquids are produced based on hydrogen production by gasification of process residues; purchase of plant power and sale of product gas can improve the economics of coal liquefaction; potential exists for integration of direct (e.g., H-Coal) and indirect (e.g., methanol) methods of coal liquefaction; and coal liquefaction in which distillable, low sulfur liquid products are made appears to be the most economical approach, though scope exists for continued evaluation in this area.
