Upgrading Powder River Coal Proves To Be Beneficial

摘要

Acompany that has developed a pro-cess to upgrade low-rank coal is nearing completion of its first commercial-scale plant in Gillette, Wyo. Already it has announced plans to construct two much larger plants. Officials of Denver-based KFx Inc. say the nearly completed plant being constructed at the Fort Union Mine in Wyoming's Powder River Basin should begin production this year. It will process 750,000 tons per year of low-rank coal using KFx's patented process with 450℉ to 500℉ heat and 450 to 500-psi pressure. The "K-Fuel" product has 30 to 40% more Btu per lb than the parent coal. It also has 70% less mercury and 30% less sulfur and nitrogen.
