Ragle, H V

The H-Coal Pilot Plant near Catlettsburg, Kentucky, was built and operated in order to collect data to facilitate establishment of the design criteria for a commercial coal liquefaction plant. In addition to process data, a great quantity of data pertaining to the materials of construction was gathered during the course of operations both through planned data gathering programs and through activities that were created of necessity. The information in this report is a presentation of materials evaluation data for all general process areas with special emphasis on the Fractionation Area. The process corrosion data were obtained through exposure and evaluation of 55 corrosion test racks composed of a variety of alloys totaling 55 in number that were exposed during four different periods to coal derived hydrocarbons produced from four different types of coal. Weld monitoring and erosion monitoring of process piping is discussed as well as specific areas of interest such as plunger coatings and refractory. The materials development from the beginning of operations to the end of the procect is summarized for both high pressure slurry block valves and high pressure letdown valves. Failure analysis was used on occasion to determine cause of failure or as a means of extracting information from various data sources. Summaries of fifteen failure analyses are presented.
