Description:
The report gives results of a Source Test and Evaluation Program at a commercial coal gasification plant using a Wellman-Galusha gasifier to produce low-Btu fuel gas from anthracite coal. Major objective of the tests was to perform an environmental assessment of the plant's waste streams and fugitive emissions. Results of the chemical analyses of the plant's waste streams indicated that all contained organic and/or inorganic components which may have potentially harmful health and/or ecological effects. In the pokehole and coal hopper gaseous emissions, CO, NH3, and possibly Fe(CO)5 were found to be of major concern. Organic compounds which were not specifically identified were of potential concern in the ash sluice water. The gasifier ash and cyclone dust contained a number of trace elements and possibly organics that may be potentially harmful. Analyses of the leachate from these two solid waste streams indicated that the leachate may have potentially harmful health and/or ecological effects; however, at a substantially lower level of concern when compared with the results of the ash and dust themselves. Overall, the indicated potential health and ecological effects of the plant's waste streams were found to be significantly lower than those for waste streams produced by gasifying bituminous coals.
