The United States Department of Energy and Energy International, Inc. have entered into a Cooperative Agreement to conduct a cost-shared UCG field test demonstrating the operation of commercial scale Underground Coal Gasification (UCG) on steeply dipping bed modules to provide synthesis gas for a small scale commercial ammonia plant. The field test and the commercial ammonia plant will be located at the North Knobs site near Rawlins, Wyoming. During this demonstration test, two or more UCG modules will be operated simultaneously until one module is completely consumed and an additional module is brought on line. During this period, the average coal gasification rate will be between 500 and 1200 tons per day. A portion of the raw UCG product gas will be cleaned and converted into a synthesis gas, which will be used as feedstock to a 400--500 ton per day ammonia plant. The UCG facility will continue to operate subsequent to the test demonstration to provide feedstock for the commercial plant. The objective of the hydrologic site characterization program is to provide an accurate representation of the hydrologic environment within the area to be gasified. This information will aid in the placement and operation of the process wells in relation to the ground water source. 21 refs., 14 figs., 6 tabs.
