Oxy-fuel combustion uses off-the-shelf technology and denitrified air for combustion in a coal-fired power plant to produce a relatively pure CO2 flue gas. Denitrification of the combustion air reduces the flue-gas volume by as much as 80%, resulting in a post combustion gas containing mostly CO2 and water. This flue gas can be cooled, condensing water, and compressed to produce a CO2 stream suitable for sequestration. Heat can be recovered from the cooling step and integrated into the thermal cycle of the power plant to minimize the energy cost of CO2 capture. This paper describes a model of the material and energy flows through a CO2-capturing oxy-fired power plant incorporating NETL's integrated pollutant-removal (IPR) process.
