The CO2 avoidance cost of a large scale O2/CO2 power plant

Paper in proceeding, 2005

This work evaluates the fixed and running costs together with the CO2 avoidance cost of an O2/CO2 combustion process. The work is based on a comprehensive process study applied to commercial process data from an 865 MWe lignite fired reference power plant and large scale air separation units (ASU), in combination, with a detailed design study of the flue gas treatment and CO2 compression train (FGTCC) [1]. All costs for the process layout proposed in [1] are gathered from industry. Although an existing reference power plant forms the basis of the work, the study is directed towards a new state-of-the-art lignite-fired O2/CO2 power plant.
