This Executive Summary presents results of Hampshire Energy's evaluation of the technical and economic feasibility of a plant to produce approximately 21,000 barrels per day of gasoline from coal. Located near Gillette, Wyoming, the plant would produce this gasoline and other marketable by-products by indirect liquefaction of 15,450 tons of Powder River Basin sub-bituminous coal. The results of the evaluation are summarized: resource assessment has confirmed the availability of the necessary coal, water, electricity and natural gas supply; a suitable plant site is available; applications have been fired for all major permits required to construct and operate the plant; only commercially proven or commercially ready technologies have been included in the plant; process licenses are available for all units requiring licensing; the Hampshire configuration of process units is technically sound regarding operability, availability, controllability and maintainability; detailed process design and preliminary basic engineering designs have been developed from which the plant's investment and operating costs have been estimated; a project execution plan and schedule for engineering, procurement and construction have been developed; plant costs have been estimated as $1790 million in 4th Quarter 1981 dollars; commercial feasibility depends on support by the US Synthetic Fuels Corporation in the form of loan and price guarantees.
