Evaluation of advanced gas processing concepts for fluidized-bed gasification. Topical report, November 1985-December 1987
First-pass plant designs and cost estimates were prepared to evaluate the CNG H/sub 2/S removal process, the CNG CO/sub 2/ removal process, and GRI's direct methanation process in the context of plants that convert western coal to 125 MMM Btu day of pipeline gas using KRW gasifiers. Four different plant designs, one prepared earlier and three developed in the study, are compared. The results of the evaluations indicate: CNG H/sub 2/S removal technology is competitive with Selexol H/sub 2/S removal technology, provided the process matures without significant increase in the capital costs; the concept for CNG CO/sub 2/ removal technology is noncompetitive with Selexol CO/sub 2/ removal technology; and direct methanation is quite attractive compared to conventional methanation.
