ABSTRACT:

Process and waste streams of commercial-scale, Lurgi/Fischer-Tropsch liquefaction facilities may be expected to contain a variety of chemical substances known or suspected to be hazardous to human health or the environment. Although it does not appear that any of the hazards are inherently insurmountable, site-specific and economic constraints may limit the level to which wastes will be treated, secured, recycled, or reduced in volume. In the present study, 79 process and waste streams from a model, commercial-scale facility have been identified for initial chemical characterization. Of these, nine gaseous emission streams, ten aqueous and solid waste streams, and numerous process streams have been characterized in more detail. Based upon the assumptions and limitations of the study, a considerable number of trace contaminants have been determined to be of potential concern, even after being subjected to a substantial degree of treatment. The degree of hazard associated with these contaminants varies considerably among streams and receptor groups.  Trace metals, polycyclic aromatic hydrocarbons, mercaptans, and tars and oils have been classified as Probable Hazards to one or more receptor groups (i.e., occupational personnel, general public, and/or ecosystems.  Aliphatics, alicyclics and fatty acids, benzenes and substituted benzenes, phenols, sulfur, nitrogen and oxygen heterocyclics, aromatic amines, nitrosamines, hydrogen sulfide, nickel carbonyl, nitrogen oxides and sulfur oxides are classified as Possible Hazards. Probable Hazards have been identified in the reverse osmosis waste stream, leachate from biosludge, and internal gasifier streams. Possible Hazards are associated with coal lockhopper vent gas, stack gas from utilities, evaporative losses from utilities generation, leachate from ash/scrubber sludge, and several internal process streams.
