Description:
This volume is an environmental characterization of three selected coal liquefaction systems: Synthoil, H-Coal, and Exxon Donor Solvent. It documents and evaluates existing environmentally significant data. System characterization includes an integrated multimedia assessment of discharges to the environment from conceptualized 7,950 cu m (50,000 bbl) per day systems. Estimates are given for the raw waste streams, treatment and control processes, treated waste stream discharges, and the effects of these discharges on the environment. Conclusions include: (1) carbon-containing residues from process phase separations are major potential environmental problems; (2) except for solid carbon-containing residues from phase separations, treatment and controls exist for removing most major waste components--however, their efficiency in controlling coal liquefaction waste streams needs to be tested; and (3) less attention has been addressed to trace organic and inorganic compounds.
