Coal feed was maintained to the extraction end of the pilot plant over a period of twenty hours. Approximately four tons of coal were processed at 9 : 1 solvent-to-coal ratio. Very limited data show the performance of the Solids Separation and Low Temperature Carbonization sections to have been satisfactory. Extraction depth, less than 50 percent, was limited by low temperatures in the extractor. Line blockages in the Solvent Recovery Section forced a halt to the run when the extract granulation system did not work, and all other means for extract removal became plugged. An earlier brief attempt to process coal was interrupted by a major leak at the inlet to the slurry preheater. During the subsequent emergency shutdown, the preheater coil plugged with coke. The middle section of the preheater was replaced with the spare coil. Other operating delays resulted from two failures of the extractor agitator shaft seals prior to the introduction of coal. Most of the leaky Conval block valves in the Hydrotreating Section have been identified; repairs will be completed next month. Loose, gritty material will be flushed from the system with condensate. Following a reassessment of the relief valve situation with the Vendor, pressure testing will proceed at 2000 psig.
