1. A process of capturing carbon dioxide (CO2) from flue gases, the process comprising the steps of:
feeding a flue gas comprising CO2 to at least one rotary packed bed direct contact cooler (RPBDCC) to cool the flue gas;
passing the cooled flue gas leaving the at least one rotary packed bed direct contact cooler (RPBDCC) to at least one rotary packed bed absorber rotating circularly, wherein a solvent provided through an inner radius of the at least one rotary packed bed absorber moves towards an outer radius of the at least one rotary packed bed absorber, and wherein the solvent reacts with the flue gas in a counter-current flow; and
passing the flue gas through a water wash to remove traces of the solvent present in the flue gas, wherein the water wash is conducted on a separate rotary packed bed (RPB).
