The report gives results of laboratory- and bench-scale steam stripping tests, using wastewaters from a fixed-bed coal gasifier at the Department of Energy's Morgantown Energy Technology Center. The wastewater was pretreated by solvent extraction (for phenol removal) and filtered prior to stripping. The report also provides engineering and environmental data for the design of steam strippers for fixed-bed gasification wastewaters. The laboratory tests were performed primarily to determine the effect of pH on contaminant removals. During the benchscale tests, samples of influent, effluent, and overhead vapor and condensate were analyzed for a number of species of potential environmental concern (dissolved gases, sulfur and nitrogen species, trace metals, organics, and other water quality parameters). Mass transfer coefficients for ammonia, carbon dioxide, and hydrogen sulfide stripping were calculated.
