Abstract

The paper presents a methodology for modeling the processes of absorptive separation of carbon dioxide (CO2) from the power plant flue gases. The absorption systems of two supercritical power plants with the capacity of 460 MWand 600 MWwere selected for the study. The process of CO2
separation from flue gases by means of chemical absorption with the use of monoethanolamine and NH3 aqueous solutions was analysed. The power plant demands for power needed for the separation, compression and transport of CO2 to the disposal site was determined. The effects of absorptive separation of CO2 for the power plant were determined, and an economic analysis of such an undertaking was conducted.
