Under these conditions, the primary products of combustion are water and CO2, with the CO2 separated by condensing the water. Figure 4 shows the major systems for a power plant equipped for oxy-combustion. Oxy-combustion overcomes the technical challenge of low C O2 partial p ressure normally e ncountered i n coal c ombustion flue g as by pr oducing a hi ghly concentrated CO2 stream (~60 %), which is separated from H2O vapor by condensing the H2O through cooling and compression. An additional purification stage for the highly concentrated CO2 flue gas may be ne cessary t o pr oduce a C O2 stream t hat m eets t ransportation an d se questration requirements. T his purification step should have significantly less cost than a conventional post-combustion capture system due to the high CO2 concentration and reduced flue gas volume. However, the appeal of oxy-combustion is tempered by a few key challenges, namely the capital cost and energy consumption for cryogenic air separation unit (ASU) operation, boiler air infiltration that dilutes the flue gas with N2, and excess O2 contained in the concentrated CO2 stream. Flue gas recycle (~70 to 80%) i s a lso n ecessary t o ap proximate the combustion c haracteristics o f a ir since c urrently-available boiler m aterials c annot w ithstand the hi gh t emperatures resulting f rom c oal combustion in pu re O 2. Consequently, the e conomic benefit of oxy-combustion compared t o a mine-based sc rubbing sy stems is limited. As shown in Figure 1, construction of a new supercritical (SC) oxy-combustion coal-fired power plant equipped with a commercially-available cryogenic ASU would increase the COE by about 80% and reduce the net plant efficiency by more than 11 % points, as compared to a new SC air-fired, coal-based power plant without CO2 capture. The parasitic power requirement for cryogenic O2 production and CO2 compression alone would increase the COE by nearly 60 %.
