Project POGO: total coal utilization, COG refinery design criteria. R and D report No. 114, interim report No. 5. [To produce power-oil-gas-other products

Abstract

The objective of this work is to develop design criteria for a conceptual design/economic evaluation for a multiproduct complex to convert coal to electric power, oil, gas, and other products. ERDA has designated this multiproduct complex, POGO, an acronym for power-oil-gas-other. POGO is an outgrowth of earlier work on a design concept referred to as coal-oil-gas (COG). Therefore, the POGO concept uses multiple processes in a preferred combination to produce a broad spectrum of environmentally acceptable fuels, plus other products, that will be economically competitive with alternative sources of these products. The objective was achieved by analyzing the capabilities of the major generic types of liquefaction processes and then by comparing the projected technical and economic performances. The next step was to compare the predicted performance of a number of potentially viable candidate combinations of processes and to recommend the preferred process combination, plus preliminary design criteria. The intent is that the resulting complex would use the best available coal conversion processes in combinations such that the byproducts or wastes of one process would form inexpensive raw materials for another process. In this manner, what might have been expenses could be turned into savings, and the final product cost could be lower than that possible with a single process plant.
