Abstract: Systems and methods are provided for performing amine capture on a heated flue gas using multiple rotating packed beds. By integrating a series of rotating packed beds to perform cooling of the flue gas, removal of CO2 from the flue gas by contact with an aqueous amine, and washing of the gaseous effluent from CO2 removal step to remove any entrained amine, the equipment footprint and overall equipment volume required for CO2 capture can be significantly reduced. The integration of cooling, CO2 removal, and washing can be integrated into a series of packed beds in part by using different packing materials in the various packed beds.
