TEK-KOL is a partnership between SGI International of La Jolla, California, and a unit of Zeigler Coal Holding Company, Fairview Heights, Illinois. TEK-KOL`s Liquids From Coal (LFC) Process uses a mild gasification process to convert low-rank coals into value added products. Two primary products are generated as a result of LFC processing: (1) Process-Derived Fuel (PDF), a high heating value, clean burning solid fuel and carbon source for a variety of utility and industrial applications, and (2) Coal-Derived Liquid (CDL), a low sulfur hydrocarbon liquid suitable for fuel oil and chemical feedstock uses. Both PDF and CDL have been successfully utilized on a commercial scale. The LFC Process has been thoroughly demonstrated at the ENCOAL LFC Demonstration Plant at the Buckskin Mine in the Powder River Basin, Wyoming. The 1,000 short ton per day plant, constructed and operated at a cost of US $90 million, was designed and built to commercial standards. Construction and initial operating costs were partially funded by the US Department of Energy (DOE) under Round Three of the Clean Coal Technology Program. The plant employs commercially available equipment and state of the art control system, and best available control technologies insure compliance with strict environmental standards. It became operational in June 1992. In the last five years, the plant and its supporting facilities have operated in an integrated mode for more than 14,500 hours. The major pieces of equipment, including the large blowers, combustors, dryer, pyrolyzer, and cooler have operated far more hours overall considering hot standby and ramping operations. The equipment has been demonstrated to operate reliably. The plant has processed 246,900 short tons of raw coal and produced 114,900 short tons of PDF and 116,100 barrels of CDL. A multi-phase process to identify and develop technically and financially viable LFC projects has been developed by TEK-KOL. Commercialization of the LFC technology is progressing worldwide. Permit work for a large scale commercial plant in Wyoming is now underway, and international commercialization activities are in progress. Worldwide opportunities for the application of the LFC Technology are addressed in this paper.
