Control technology assessment for coal gasification and liquefaction processes, Exxon Coal Liquefaction Pilot Plant (ECLP), Baytown, Texas.

A control technology survey was conducted at Exxon Coal Liquefaction Pilot Facility (SIC-5161), Baytown, Texas in September, 1981, to assess methods used to prevent worker exposure to hazardous agents in coal conversion facilities. Distinguishing features of the Exxon process were the use of a hydrogen donor solvent in the liquefaction reactor, catalytic hydrogenation of solids free spent solvent, and the use of vacuum distillation for the separation of solids and liquids. Potential hazards included exposures to polynuclear aromatics, fire, noise, coal dust, phenols, aromatic amines, ammonia (7664417), hydrogen-sulfide (7783064), and hydrocarbon vapors. Housekeeping techniques were used to reduce contact with coal-tars. Tools were cleaned daily. Pressure safety relief valves were inspected regularly. An automatic corrosion monitoring system was used. Entry into the process area was regulated and required protective equipment. A comprehensive program was in effect for area sampling and personal monitoring. Personal hygiene and employee education and training were stressed. A medical surveillance program included physical and skin examination, medical history, and clinical tests. The author concludes that the work practices and engineering controls observed have made the facility a clean and safe place to work and should be considered for incorporation into the design of future commercial operations.
