H-Coal Pilot Plant 1980 Turnaround Report. Revision

摘要

Since the start of H-Coal operations on March 11, 1980, the plant has operated for a total of 2949 hours. Of this total time on stream, 2572 hours were expended circulating oil and 377 hours with coal feed to the unit. Approximately 1148 tons of coal were processed during this period. The coal processed was Kentucky number11. On November 14, 1980, the H-Coal Pilot Plant was shut down for an overall turnaround maintenance program. During the turnaround period, all operating activities in the 100, 200, and 400 Areas were terminated to enable inspection and, as necessary, repair of all major equipment. Particular emphasis was placed on inspection of the coal liquefaction section (Area 200) which had not been inspected since the initial start-up in January 1980. Additionally, the Sour Water and Sour Gas Sections (Area 400) were thoroughly inspected due to previous evidence of cooling water corosion in several exchangers. During the turnaround, except for a very brief period, the Waste Oil Recovery Section (Area 600) continued to operate to recover start-up oil. In general, equipment inspection did not reveal any unexpected surprises and the turnaround maintenance work progressed very smoothly. By January 10, 1981, the turnaround maintenance work had been completed and plant start-up was initiated. (ERA citation 09:011405)
