Title: Assessment of trace contaminants from a model indirect liquefaction facility. Volume IV. Public health hazards of Lurgi/Fischer-Tropsch coal liquefaction

Technical Report ·
OSTI ID:6808012

This analysis identifies the public health hazards of wastes from Lurgi/Fischer-Tropsch coal liquefaction. First, body burdens that result from exposure to Lurgi/Fischer-Tropsch wastes are compared to body burdens from other sources of the same chemicals. Second, ambient concentrations of pollutants from Lurgi/Fischer-Tropsch operations are projected and compared to various air and water quality standards. Quantitative characterization of liquefaction wastes is limited to a few specific process streams. Consequently, quantifiable measures of risk are restricted to those streams. For waste streams that are not quantified, we used qualitative measures of risk. Results of the quantitative assessment indicate: (1) Ambient atmospheric concentrations of ammonia, hydrogen sulfide, sulfur dioxide, nitrogen oxides, arsenic, nickel carbonyl, and mercury - seven out of 73 substances for which risks were quantifiable - are projected to violate or be within one order of magnitude of acceptable levels for public exposure. However, due to their toxicity and slow biodegradation, only the trace elements (Al, As, Be, Bo, Cd, Cu, F, Fe, Pb, Mn, Hg, Ni, Se, V) and nickel carbonyl are projected to be of concern of public health. (2) Ambient aquatic concentrations of trace elements, phenols, polynuclear aromatic hydrocarbons, substituted benzenes, mercaptans, fatty acids, and aromatic amines will violate or be within one order of magnitude of acceptable levels for public exposure. Trace elements, polynuclear aromatic hydrocarbons, and phenols are projected to be of concern to public health. (3) Unquantified waste streams currently release carcinogens, co-carcinogens, and toxic substances to the environment. All carry the potential for public health impact. (4) The flaring of process gas during normal operations may release carcinogens and toxic chemicals to the atmosphere. The effect of flaring on gas composition needs to be assessed. 45 references, 5 figures, 15 tables.
