Leaching studies on IGT U-GAS gasifier ash
Technical Report

OSTI ID:6694776
This report describes a series of leaching tests performed by Energy Impact Associates on samples of coal ash from Run 133 of the Institute of Gas Technology's U-GAS gasifier operating at 14.6 psig. The work was performed as part of the environmental assessment activity for the proposed Memphis Industrial Fuel Gas Demonstration Plant to determine if the ash would be considered hazardous under the draft regulations of the Resource Conservation and Recovery Act (RCRA). The tests were conducted to determine what major, minor and trace elements, as well as organic compounds, entered the leachate following a specified leaching procedure. Three leaching procedures were employed, including the EPA Extraction Procedure and EIA-modified ASTM methods at pH = 7 and pH = 8 (to simulate the surface water and groundwater conditions at the IFGD plant site, respectively). Results of this study show that the ash would not be classified as hazardous under RCRA with a considerable margin of safety. Moreover, no toxic organic compounds were detected at the minimum detection limit from all procedures, although low levels of phenols were observed from the EPA test. No degradation of local water quality resources should occur from disposing of these wastes on the plant site in a non-acid environment, as is presently planned.
