Abstract
The Joint Coal Gasification Program of the Energy Research and Development Administration and the American Gas Association was organized to accelerate the development of new processes through the pilot plant stage for producing pipeline gas from coal. There are five processes in the program at various stages of development. Two pilot plants are in operation, the IGT Steam-Oxygen HYGAS and the Conoco CO/sub 2/ Acceptor. Two others, BCR BI-GAS and ERDA-PERC Synthane, have been completed and are undergoing final checkout or shakedown. The last, IGT Steam-Iron HYGAS is in the final stages of construction. As evaluation contractor for the program, C.F. Braun and Co. has the responsibility for comparative evaluation of these processes. For comparative evaluation, commercial concept designs have been developed using process data provided by the process development contractors and gas processing technology available from process licensors. The capital and operating costs for each of the commercial concept designs have been estimated using a consistent set of guidelines formulated for this specific purpose. The cost of pipeline gas from each of the processes was computed in accordance with the procedures included in the guidelines, and is compared with the cost of gas from a modified Lurgi process.
