Abstract:
1. A CO 2 recovery system including an absorption tower that a regeneration tower that the CO a condenser that receives CO a separation drum that receives the CO two or more compressors that compress the CO a heat supplying unit that supplies the heat to the regeneration tower for heating any one of the lean solution and the semi-lean solution; a bifurcated path through which any one of a part of the lean solution extracted from a portion of bottom of the regeneration tower and the semi-lean solution extracted from a midcourse of the regeneration tower bifurcates and passes; a circulating path suitable for extracting any one of the part of the lean solution and the semi-lean solution through the bifurcated path, heat-exchanging with compression heat that is generated when CO at least two heat exchangers that are located on intersections between the bifurcated path and a path suitable for conveying the CO
