Environmental, Health, and Safety Assessments for Direct Coal Liquefaction. Volume 8D. Environmental Transport, Fate, and Effects of Wastewaters

摘要

Direct coal liquefaction is a developing technology for which detailed environmental studies are few and more complete information is needed for compliance with Federal Acts. This paper is a critical review of the literature on environmental transport, fate, and effects of direct coal liquefaction wastewaters including cooling tower drift with emphasis on the SRC I and II, H-Coal, and Exxon Donor Solvent processes. It was done to assess the status of research that has been accomplished and to serve as a basis for planning future research programs. The review is organized around the following topics: (1) the initial issues that were believed to be important for the assessment of the transport, fate, and effects of direct coal liquefaction wastewaters; (2) the research done to address these issues; (3) the initial issues that were resolved by this research; and (4) additional or new research needs. 70 references, 7 figures, 15 tables.
