OSTI ID:6830390
The Institute of Gas Technology's (IGT) U-GAS process for medium-Btu fuel gas offers a means to produce a clean fuel from coal with minimal environmental impact. The U-GAS process uses an ash agglomeration mechanism in a single-stage fluidized bed coal gasifier to achieve high coal conversions. The U-GAS pilot plant has been operated since 1974 in support of the U-GAS process development. During this time, several types of coal and char have been successfully gasified with coal conversion efficiencies as high as 98.5%. In over 10,000 hours of total operation, 123 pilot plant tests have been completed with 1859 tons (1693 Mg) of coals gasified. Steady-state operations at pressures up to 60 psia (413 kPa) and temperatures up to 2000/sup 0/F (1093/sup 0/C) have produced a good quality fuel gas with a heating value as high as 284 Btu/SCF (10,579 kJ/m/sup 3/). Through this extensive testing and development program, the U-GAS process feasibility has been firmly established and an extensive data base acquired for scale-up. A commercial plant to produce medium-Btu gas from coal using this process will be built near Memphis, Tennessee. The fuel gas produced will be supplied to industrial customers via a short distance pipeline in the Memphis area.
