Gasification of Residual Materials from Coal Liquefaction. Type IV Sustained Pilot Plant Evaluation of SRC-II Vacuum Flash Drum Bottoms from Powhatan Coal

摘要

A Type IV Sustained Pilot Plant demonstration of SRC-II vacuum flash drum bottoms obtained from the liquefaction of Powhatan coal at Ft. Lewis, Washington was successfully completed at Texaco's Montebello Research Laboratory. Approximately 83 tons of SRC-II residue were gasified during four pilot plant runs at 1200 and 600 psig. The longest continuous run was 127 hours, and a total of 237 hours of operation was accumulated. Operating conditions were held substantially constant throughout the demonstrations. The dry syngas produced contained over 90 (vol) percent hydrogen plus carbon monoxide. No major operating problems were experienced and all of the key phases of the gasification were demonstrated. Steady state operating conditions were obtained in all streams, and extensive environmental data were obtained. (ERA citation 05:037481)
