Operation of the Wilsonville Advanced Coal-Liquefaction R and D Facility, Wilsonville, Alabama. Annual Technical Report, January-December 1981 (Runs 222 Through 235).

摘要

This report summarizes the 1981 operating and test data obtained at the six ton per day Advanced Coal Liquefaction Research and Development Facility in Wilsonville, Alabama. Special emphasis is placed on data accumulated during the fourth quarter of 1981. The Wilsonville R and D Facility was in operation 71% of 1981 (70% of the fourth quarter) with scheduled shutdowns accounting for 23% of the downtime (28% during the fourth quarter). Kentucky 9 coal from the Fies mine was processed in all runs conducted during 1981 (Runs 222 through 235). The hydrotreater (HTR) unit was brought on stream successfully in May 1981. The three process units of the Wilsonville facility were operated in a non-integrated mode during the second half of 1981. Significant data was obtained in the following areas in the SRC Unit: operation at low- and high-severity reaction conditions for single stage liquefaction, process solvent quality, demonstration plant process simulation, and operation of lower-residence-time high-pressure separator. In the CSD Unit: modifications to the first-stage ash-removal system, unit performance at increased feed rates, and deashed SRC viscosity on storage at 525 exp 0 F. In the HTR Unit (brought on-line 23 May) unit performance at several reaction conditions, product yield and qualities, and catalyst aging and recovery studies. (ERA citation 08:035003)
