A commercial coal-oil-water mixture processing facility

"CoaLiquid, Inc. (CLI) has been in the coal-oil-mixture (COM) business for over five years. The initial pilot processing facility was replaced by a 2000 barrel per day commercial production facility in August 1979. For over two years CLI has been expanding its efforts and conducting large-scale production and combustion demonstrations successfully in many locations across the United States. To facilitate the marketing effort, CLI has recently constructed a special trailer containing all equipment needed for a temporary COM retrofit.CoaLiquid has conducted commercial-scale combustion demonstrations in the following types of combustion units: kilns, calciners, industrial boilers, blast furnaces and driers.IntroductionCoaLiquid, Inc. officially dedicated its plant on August 31, 1979, at a ceremony presided over by the then Governor of Kentucky, The Honorable Julian Carroll. The dedication marked the culmination of over three years of research and development work and marked the beginning of a new era of coal-oil-mixtures as a commercial commodity in the marketplace. As the first such plant in the United States, it set the tone for construction to follow.CLI was originally owned and managed by a group of entrepreneurs from Kentucky who had developed the process and constructed the plant on purely private investment and conventional financing. Beginning in late 1976, with a pilot-scale operation, also located in Shelbyville, Kentucky (near Louisville), CLI began producing a stable mixture of 50070 coal, 30% to 40% oil and 10% to 20% water by weight. The technology employed was developed by Eric C. Cottell of Long Island, New York and is covered by U.S. Letters Patent No. 3,941,552. Since the pilot plant operation, CoaLiquid has made many refinements to its process and in fact has added new technology to its portfolio of patents and patents pending. Further refinements to the product now produce a stable mixture of 50% coal, 40% No.6 fuel oil and 10% water by weight."
