An abbreviated 55-hour extraction run was completed in December; 15 tons of coal were processed as a 15 percent slurry. The depth of extraction was 62 percent. The revised extract disposal system operated satisfactorily. Coal processing was abruptly terminated when the lower extractor agitator shaft seal failed, bringing an end to Run 004. Warm solvent has been circulated through most of the hydrotreating section of the pilot plant under a 2700 psig nitrogen blanket. Leaks at the heads of the absorber and the entrainment separator persisted beyond the end of the month. Much of January is scheduled for maintenance and modification in the hydrotreating section. In addition to the repair of leaky vessels and Conval valves, the attritor loops will be removed from the two hydrogenation reactors as requested by the licensor. An apparent high phenol level of the treated industrial waste water discharge to the Ohio River exceeded EPA limits during December. An extensive effort to define and resolve the problem has begun.
