689. DENT, F. J. Use of Oxygen for Town-Gas Manufacture. Gas World, vol. 128, 1948, p. 384-385. Proposal for pressure gasification of coal linked with a synthetic-oil process for the production of town gas. Data so far available indicate that pressure gasification might assume the basic position in the gas industry that carbonization now occupies provided the demand for gas outstrips that for coke; the process also would have the advantage of flexibility in operation during peak periods. As compared with the Fischer synthesis process, gasification under pressure, with withdrawal of part of the gas for oil synthesis, shows many advantages. Assuming an overall thermal efficiency of about 70%, the gas cost is reduced to 0.65 d. per therm.
