Derivation of power loss factors to evaluate the impact of postcombustion CO2 capture processes on steam power plant performance

Abstract When integrating a post-combustion CO 2 capture process and a CO 2 compressor into a steam power plant, the heat duty for the regeneration of the solvent (and the corresponding steam extraction) shows to be the largest contributor to the overall net efficiency penalty of the power plant. One parameter which varies from plant to plant and which significantly affects the impact of steam extraction from the steam turbine on the power plant efficiency is the pressure in the IP/LP crossover. In this work, the dependency of the energy penalty on the quantity and quality of the heat duty is analysed and quantified for three state-of-the-art hard coal fired power plant configurations with different pressure levels in the IP/LP crossover.
