Hydrogen production and carbon dioxide recovery from KRW oxygen-blown gasification.

PDF Version Also Available for Download.

Description

An oxygen-blown KRW integrated gasification combined-cycle plant producing hydrogen, electricity, and supercritical-CO{sub 2}, was studied in a full-energy cycle analysis extending from the cord mine to the final destination of the gaseous product streams. A location in the mid-western US was chosen 160-km from Old Ben No.26 mine which ships 3,866 tonnes/day of Illinois No.6 coal by diesel locomotive. Three parallel gasifier trains, each capable of providing 42% of the plant's 413.5 MW nominal capacity use a combined total of 3,488 tonnes/day of 1/4 inch prepared coal. The plant produces a net 52 MW of power and 3.71 x 10{sup ... continued below

The plant produces a net 52 MW of power and 3.71 x 10{sup 6} nm{sup 3}/day of 99.999% purity hydrogen which is sent 100 km by pipeline at 34 bars. The plant also produces 3.18 x 10{sup 6} nm{sup 3}3/day of supercritical CO{sub 2} at 143 bars, which is sequestered in enhanced oil recovery operations 500 km away. A CO{sub 2} emission rate of 1 kgCO{sub 2}/kWh was assumed for power purchases outside the fence of the IGCC plant.
