Engineering assessment of CO{sub 2} recovery, transport, and utilization.
The need to establish benchmarks for available power-generating cycles having reduced atmospheric emissions of CO{sub 2} served as the basis for this study. Innovative process technologies need this benchmark so they can be appreciated in their proper perspective. An oxygen-blown KRW coal-gasification plant producing hydrogen, electricity, and supercritical-CO{sub 2}, was studied in a full-energy cycle analysis extending from the coal mine to the final destination of the gaseous product streams. A location in the mid-western US 100 mi from Old Ben No.26 mine was chosen. Three parallel gasifier trains, each capable of providing 42% of the plant's 413.5 MW nominal capacity use 3,845 tons/day of Illinois No.6 coal from this mine. The plant produces a net 52 MW of power and 131 MMscf/day of 99.999% purity hydrogen which is sent 62 mi by pipeline at 34 bars. The plant also produces 112 MMscf/day of supercritical-CO{sub 2} at 143 bars, which is sequestered in enhanced oil recovery operations 310 mi away.
