Experimental evaluation of coal conversion solid waste residuals. Progress report, August 1-October 31, 1979
Activities are underway to investigate basic phenomena that would assist demonstration and commercial sized coal conversion facilities in the environmentally acceptable disposal of process solid waste residuals. The approach taken is to consider only those residuals coming from the conversion technology itself, i.e. from gasification, liquefaction, and hot-clean-up steps as well as residuals from the wastewater treatment train. Residuals from the coal mining and coal grinding steps will not be considered in detail since those materials are being handled in some manner in the private sector. Laboratory evalations have been conducted on solid waste samples of fly ash from an existing Capman gasifier. ASTM-A and EPA-EP leaching procedures have been completed on sieved size fractions of the above wastes. Data indicate that smaller size fractions pose greater contamination potential than do larger size particles with a transition zone occurring at particle sizes of about 0.05 inches in diameter. Ames testing of such residuals is reported. Similar studies are under way with samples of H-Coal solid waste residuals.
