Additional runs were attempted under various operating conditions using the liquefaction section of the PDU. Some difficulties were encountered. Some low-ash solvent-refined lignite (SRL) was produced, but product quality was not consistent. Continued major emphasis was given to maintenance of the PDU to allow operation. Laboratory autoclave testing of a Chilean lignite was completed with results comparable to those obtained with North Dakota lignite. Cost evaluation studies for three liquefaction processes (Synthoil, CBFFC, and SRL) at the same output indicated that the SRL processes had the lowest cost on a Btu basis. An economic study of electrical generation costs indicated that as-mined lignite had lower costs per kilowatt hour than did SRL in new generating facilities, either for mine mouth or load center facilities. SRL as a clean fuel might be justified for use in older or peaking plants by environmental considerations.
