Abstract: A system and method are provided for capturing carbon dioxide from a flue gas. The system includes an absorber, a stripper, a cooling system and a control module. The cooling system is adapted to independently cool (a) a flue gas upstream from an absorber flue gas inlet and (b) a carbon dioxide-lean carbon capture solution being delivered to each of a plurality of lean carbon capture solution inlets at the different levels of the absorber. The control module includes a controller and a plurality of temperature sensors. The controller is responsive to the plurality of temperature sensors provided at each of the different levels of the absorber to control operation of the cooling system and thereby maintain a desired temperature profile at the different levels of the absorber to enhance rich loading of carbon dioxide from the flue gas to a carbon capture solution and reduce energy requirements for lean carbon capture solution regeneration in the stripper.
