Abstract |
The report contains detailed organic analysis data on six streams, trace element and organic data on the solid waste leachates, and trace element data on the feed coal, all of which were not included in the original report, (PB-249 940). Samples from six streams were analyzed to provide a detailed organic characterization of emissions and potential fugitive emissions form an operating Chapman low-Btu gasifer using Virginia bituminous coal. The streams were: coal feeder vent discharge, separator vent discharge, separator liquor, separator tar, gasifier ash, and cyclone dust. All streams except the ash and dust contained organic compound concentrations of concern to health when evaluated using SAM/IA methodology. Phenols in the separator vent discharges and liquor and fused polycyclics in the coal feeder vent discharge and the separator tar were of greatest concern. When compared to screening data, potential effects were lower, but relative ranking of streams was essentially unchanged. The ash and dust were subjected to leachate extraction tests using the RCRA method and deionized water. No organics were found in the leachates. Concentrations of trace elements in the RCRA and deionized water leachates were different, but were found to have low potential for causing adverse health or ecological effects. |
