Young, R J

The memorandum provided information on a site visit made to the Pittsburg and Midway Coal Mining Company located in DuPont, Washington, to become more familiar with the solvent-refined coal (SRC) process, and to evaluate the facility for inclusion in the industrial-hygiene study. In the process raw coal was pulverized, mixed with a solvent with a boiling range of 500 to 600 degrees-C and the resultant slurry passed through a fired preheater to a reactor. In the reactor the coal was almost completely dissolved in the solvent. Unreacted gases were removed from the process stream beyond the dissolver. Ash and undissolved coal were removed by filtration from the degassed liquid. Filtrate passed through a fired preheater and to a vacuum flash drum. The bottoms from the drum, SRC, flowed to a water-cooled stainless steel belt and to storage. The SRC process is the only liquefaction pilot facility; the industrial-hygiene study should be limited to gasification pilot facilities due to the existing work being conducted by Gulf Oil Corporation.
