Operation of the Wilsonville SRC Pilot Plant in Support of SRC-I Demonstration Plant

摘要

The SRC-I Pilot Plant in Wilsonville, Alabama, began processing the designated demonstration plant coal (Kentucky 9) on 1 February 1979, with Run 157. This report analyzes the pilot plant data from Run 157 through Run 229, which ended on 21 June 1981. The operating results for Kentucky 9 coals from various mines (Pyro, Lafayette, Dotiki, and Fies) are compared and analyzed. This includes data on the effects of variations in the coal space rate, hydrogen partial pressure, and reaction temperature on SRC yield, sulfur level, and hydrogen consumption. Runs 209, 210, 218-220, 223-226, and 227 were designated as Demonstration Plant Runs (preliminary and extended). These runs were conducted to simulate the conditions specified for the design of the 6000 TPD SRC-I Demonstration Plant. The observed yield structure for these runs is compared with the specified design yield. In addition, solvent sufficiency (during trouble-free operating periods), solvent quality stabilization, and the adequacy of coal-derived anthracene oil (Allied 24CB) as a startup solvent have been confirmed. Finally, the variations in the recycle solvent quality over an extended period, the corrosive effects of process derived liquids, and the effectiveness of sodium carbonate as a corrosion inhibitor are documented and discussed.
