Description:
The report gives results of a study to determine water consumption and environmental impacts of coal conversion processes in Western states. Part 1 gives brief descriptions and process water requirements for nine conversion processes. Detailed designs and analyses are given for the Hygas, Synthane, and Solvent Refined Coal (SRC) processes, and for Lurgi combined-cycle power generation. At three proposed sites (in North Dakota), New Mexico, and Wyoming), complete water requirements and effluents, including all mining and related off-site uses, are given for the power, Hygas, and SRC plants. The Synthane process is analyzed only at the Wyoming site. Part 2 gives analyses of influent and effluent waters, with examples for study. For the three selected plants at the North Dakota site, source water of good quality is assumed to be cheap and available. For three plants in New Mexico, source water will be available but is brackish. All the plants at the Wyoming site receive sewage from a satellite town; additional fresh water is available but is assumed to be expensive. For each process at each site (10 cases) an integrated water treatment plant block flow diagram is given with approximate costs and energy requirements.
