With the completion of the large pilot plant (ECLP) operation, the technical feasibility of the EDS process for liquefying a range of coal types has been demonstrated. The integrated pilot plant, laboratory and engineering program has provided the knowledge and engineering data needed to design the liquefaction section of a commercial-size coal liquefaction plant when commercially justified. Some elements of the EDS program are continuing. These include work on the development of a unique type of boiler to fire coal liquefaction bottoms. Since the EDS coal liquefaction bottoms contain roughly 30% of the feed carbon, they can be used to heat the coal slurry and to provide steam for the process. Utilization of the bottoms is essential for optimizing process efficiency and economics. Studies are also continuing to define any potential hazards to health associated with materials produced in the EDS process.
