Aqueous and organic phases of product streams frequently come into contact in synfuels processes. Contacts occur most commonly in gas quench operations and result in the production of a large volume of very complex water/organic mixtures. As a result of contact, chemical transformations may occur that can influence the toxicity of a given material. The chemical thermodynamics and kinetics of such reactions are strongly influenced by the complex matrix in which they occur. To determine the potential health effects of synfuel wastewaters, chemical characterization as well as toxicological evaluation of representative process materials is required. Samples examined included coal-gasification quench waters from the HYGAS pilot plant (Institute of Gas Technology) and from the University of North Dakota Energy Technology Center (UNDETC) pilot plant, and certain oil-shale process waters, and tar-sand process waters. Detailed characterization of the extractable and chromatographable organics was performed using capillary column gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). The acidic, basic, and neutral components were analyzed in samples obtained before and after the various treatment strains. These studies showed that most of the chromatographable organics are removed if a solvent extraction is followed by an activated-sludge/powdered-activated-carbon treatment. However, neutral and basic organic materials that were present in small amounts and polar material that was not identified at the time were not removed.
