Source term estimates for synthetic fuels technologies: direct coal liquefaction technologies

OSTI ID:6025077

Development of the synthetic fuels industry has raised concerns relating to the risks involved in the potential release of toxic or hazardous substances in the production and utilization of synthetic fuels. The Environmental Sciences Division, Oak Ridge National Laboratory (ORNL) is currently performing both health and environmental risk assessments associated with three synthetic fuels technologies, namely, direct liquefaction, indirect liquefaction and oil shale processing. One key element of risk assessment is the characterization of streams of concern. The objectives of Task 1 were to prepare source term estimates for waste streams generated by commercial-scale facilities employing the eight selected synfuels processes and estimate product/by-product generation rates. Because these synfuels processes are not generally operating at commercial scale, source term estimates are based largely upon published process conceptual designs and test data obtained from bench-scale, pilot or demonstration units. Moreover, due to the limited publicly available data relating to the performance of pollution controls applied to waste streams generated by synfuels processes, source term estimates for controlled waste streams reflect control efficiencies extrapolated from similar applications in other industries. This report presents the Task 1 results for direct liquefaction technologies (i.e., EDS, SRC-I, SRC-II and H-Coal synfuels facilities). Base plant configurations evaluated in this report have been adapted from conceptual commercial plant and demonstration plant design information provided by process developers for the subject technologies.
