doi  abstract   bibtex   
© 2015 Elsevier B.V. Post-combustion carbon dioxide (CO2) capture using aqueous monoethanolamine (MEA) has been the most widely implicated method utilizing existing coal-fired power plants. However, the heat and energy requirement of the solvent regeneration and CO2 liquefaction results in a 30% decrease in net power output, which is called "power de-rate". In this study, optimum operating conditions of the integrated CCS process are proposed by simulation-based parametric optimization to reduce the power de-rate. Post-combustion CO2 capture with aqueous MEA and CO2 liquefaction integrated with a 550MWe supercritical coal-fired power plant was simulated base on the data of a 0.1MW pilot plant in South Korea. The stripper operating pressure and liquid to gas ratio were chosen as the manipulated variables based on the variable evaluation. The power de-rate was reduced to 17.4% when operating at optimum conditions.
