Long-term leaching tests with coal gasification slag: Final report
The primary objective of this study was to characterize leachate quality for representative coal gasification solid residues in an environment that represented one of the disposal practices that TVA uses. An additional objective was to compare the leachate quality for solid residues produced by gasification of different types of coal. The approach taken was to investigate the chemical characteristics of waters in contact with coal gasification slags disposed in small surface impoundments (field test cells). Slags from gasification of two coals were placed in lined field test cells. One feed coal was a low sulfur (0.4%) western bituminous coal produced by Southern Utah Fuel Company (SUFCO). The other feed was Illinois No. 6 coal, a medium sulfur (2.8%), midwestern bituminous coal. 9 refs., 17 figs., 19 tabs.
