This topical report is the first for the UOP Bench-Scale Co-processing contract. The objective of this contract is to extend and optimize the UOP single-stage, slurry-catalyzed co-processing scheme. UOP co-processing uses a single-stage, slurry-catalyzed scheme in which petroleum vacuum resid and coal are simultaneously upgraded to a high-quality synthetic oil. A highly active, well-dispersed catalyst permits operations at moderate- and high-severity reaction conditions with minimum detrimental thermal reactions. In this process, finely ground coal, petroleum resid, and catalyst are mixed, combined with hydrogen, and then directed to a single-stage reactor, where the simultaneous upgrading of the petroleum resid and coal occurs. The reactor effluent is directed to a series of separators, where a hydrogen-rich gas is recovered and recycled back to the reactor inlet. The balance of the material is sent to a series of separators, where the light gasses, light oil, vacuum gas on (VGO), catalyst, unconverted coal, ash, and residues are recovered. The catalyst is recycled back to the reactor. The UOP co-processing scheme is designed to be integrated into a conventional petroleum refinery. the hydrocarbon products from the co-processing unit will be sent to the refinery for final upgrading to finished products. A major focus of this …

This Task Technical Plan summarizes work required to project the benzene emissions from the Late Wash Facility (LWF) as well as update the benzene, mercury, and NO{sub x} emissions from the remainder of the Defense Waste Processing Facility (DWPF). These calculations will reflect (1) the addition of the LWF and (2) the replacement of formic acid with nitric acid in the melter preparation process. The completed calculations will be used to assist DWPF in applying for the LWF Air Quality Permit.
