In-situ coal gasification: a future source of energy. [Pricetown, WV]
An Underground Coal Gasification (UCG) field test in bituminous coal was successfully completed near Pricetown, West Virginia. A methane rich product gas with an average heating value of approximately 25 Btu/SCF (9315 KJ/M/sup 3/) was produced at low air injection flow rates during the reverse combustion linkage phase. The heating value of the gas produced during the linkage enhancement phase was 221 Btu/SCF (8230 KJ/M/sup 3/) with air injection. The high heating value of the gas was the combined effect of residence time, flow pattern, injection flow rate, injection pressure and back pressure. During the gasification phase, a gas with an average heating value of 125 Btu/SCF (4658 KJ/M/sup 3/) was produced with only air injection, which resulted in an average energy production of 362 MMBtu/day (382 GJ/day). The data obtained from this test are being used to design an effective program that will lead to a commercial demonstration and subsequently, commercial acceptance of this technology for bituminous coals by the early 1990's.
