Post-combustion capture of carbon dioxide from fossil fuel fired power plants is essential for the control of greenhouse gas emissions. The major challenge of the amine-based solvent systems, which is the state-of-art technology, is the high capital and operating costs. The gas pressurized stripping process utilizes a high-pressure stripping gas to reduce the water vaporization energy consumption and produce high-pressure carbon dioxide gas. This paper presents the design and the comparison of energy and economic performance of three processes, including the conventional simple stripping (SS), the basic gas pressurized stripping (BGPS) operated at different temperatures, and a modified GPS (MGPS).
