Technical Assessment of Environmental Control Technologies for the Exxon Donor Solvent Commercial Plant

摘要

This report is a continuation of the analysis of the adequacy of proposed environmental control technologies in conceptual commercial designs of coal liquefaction plants. The first report assessed the adequacy of environmental controls for the Breckinridge Phase 0 and Revised Phase 0 designs for the H-Coal liquefaction process. This report is an analysis of environmental controls for the Exxon Donor Solvent (EDS) process for the processing of Wyoming coal in the bottoms recycle mode. The results of this analysis have shown that the proposed control technologies for wastewater treatability will be adequate. Disposal technologies for EDS solid effluents will also be adequate to handle the expected quantities and types of materials. Atmospheric emissions expected from the plant will still be considerable, even after application of controls. Recommendations to reduce the mass emission rates of these atmospheric emissions are suggested. (ERA citation 09:011406)
