Gold, H., J. Nardella, AND C. Vogel. POLLUTION CONTROL PRACTICES--FUEL CONVERSION AND ITS ENVIRONMENTAL EFFECTS. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/J-79/032 (NTIS PB80119704).
Description:
The paper examines water-related effects that could be expected from siting specific conversion plants at given locations in the major coal and oil shale bearing regions of the U.S. A total of 90 plant/site combinations were studied: 48 in the Central and Eastern U.S., and 42 in the Western. The synthetic fuel technologies examined include: coal gasification to convert coal to pipeline gas; coal liquefaction to convert coal to low-sulfur fuel oil; coal refining to produce a de-ashed, low-sulfur solvent-refined (clean) coal; and oil shale retorting to produce synthetic crude. The results presented include the range of water requirements, the conditions for narrowing the range and optimizing the use of water, the ranges of residual solid wastes, and the cost and energy requirements for wastewater treatment. A comparison of the water requirements with those of two recently published studies shows widely varying estimates and emphasizes the need for both site- and design-specific calculations.
