One objective of the H-Coal Pilot Plant was to evaluate materials of construction and establish guidelines for materials for commercial application. In order to meet that objective, a Corrosion Monitoring Program was begun in May 1980. The University of Kentucky Institute for Mining and Minerals Research (IMMR), under ASFI Subcontract HC-59, prepared corrosion coupons for exposure in various areas of the H-Coal process, primarily in the high pressure hydrogenation section, but also including the atmospheric fractionator and sour water and sour gas areas. A total of 33 racks consisting of combinations of 32 different alloys were exposed during four different exposure periods (approximately 200 coupons per exposure period) from May 1980 to November 1982. The coupons were exposd to four different types of coal: Kentucky No. 11, Illinois No. 6, Kentucky No. 9, and Wyodak coal separately and/or in various combinations. To extract as much data as possible, the coupons were examined by various techniques including weight loss determination, metallographic examination and microanalytical examination. The original data, results of the various examinations, trend analysis, discussion of meaningful correlations, and conclusions are presented in this report.
