The Institute of Gas Technology has developed an advanced single-stage fluidized bed coal gasification process - the U-GAS Process - to produce a low- to medium Btu fuel gas from a variety of feedstocks including highly caking, high-sulfur, and high-ash coals. The gas produced is environmentally acceptable and economically attractive. A 24 tons per day pilot plant has been in operation since 1974. Recent tests conducted with different feedstocks have achieved overall coal utilization exceeding 98% with long-term continuous steady-state operation. Extensive pilot plant testing has established process feasibility and provided a complete data base for scale-up and design of the first commercial plant. The U-GAS process accomplishes four important functions in a single-stage fluidized bed gasifier: It decakes coal, devolatilizes coal, gasifies coal, and agglomerates and separates ash from bed char. The next logical step in the commercialization of the U-GAS technology has been taken. The U-GAS process has been selected by the Memphis Light, Gas and Water Division of the City of Memphis for construction of a plant in Memphis to produce 50 billion Btu of industrial fuel gas from 3160 tons of western Kentucky bituminous coal daily. The plant will produce about 175 million SCF per day of medium-Btu gas. The gas produced will be distributed by relatively short pipelines to industrial customers in the Greater Memphis area for use as industrial fuel and for process heat.
