Materials performance at the Exxon Coal Liquefaction Pilot Plant
The Exxon Coal Liquefaction Pilot Plant (ECLP) was part of an integrated research and development project cost shared by the US government and a consortium of US, Japanese, West German, and Italian industries. Utilizing the Exxon Donor Solvent (EDS) process, the pilot plant was designed to process 250 tons of coal as received per day. It operated for 10,700 hours over a period of 26 months on three classes of coal: bituminous (Illinois No. 6); sub-bituminous (Wyoming); and Texas lignite. Testing for each coal was followed by a plant turnaround including a thorough equipment inspection. An integral part of this project was evaluation of the performance of materials of construction in order to develop a data base for the design of durable and reliable equipment for a commercial size plant. The materials evaluation program was developed during the early design phase of ECLP and was, wherever possible, integrated into the plant design and equipment specifications. The program involved the use of conventional corrosion racks in collaboration with Oak Ridge National Laboratory; corrosion probes (resistance and polarization types); inspection of designated components; stream sampling; and NDE surveillance including ultrasonic erosion monitoring. A summary of materials performance in the various sections of the plant is presented.
