Design and Economics of a Plant to Convert Eastern Bituminous Coal to Pipeline Gas or Power Using KRW Gasifiers with In-Bed Desulfurization. Topical Report November 1987-September 1988

摘要

A first-pass design and cost estimate were prepared for a coproduction plant to convert eastern bituminous coal alternately to pipeline gas or power using KRW gasification with in-bed desulfurization. The direct methanation process and other gas processing units convert syngas into pipeline gas, or a combined cycle power plant consumes the syngas to make power. The coproduction plant produces daily peaking power on weekdays and pipeline gas during nights and weekends. The coproduction of pipeline gas and daily peaking power in one gasification facility is competitive with a separate daily peaking power plant and a separate pipeline gas plant. If the daily peaking power can be sold at a premium price, the cost of producing pipeline gas is reduced.
