Abstract: The present invention relates to a system and a method therefor capable of reducing the amount of heat which must be supplied to a regeneration tower for regenerating an absorbent in an acid gas capture process for such acid gas as carbon dioxide and provides a low energy-type acid gas capture system and method using recirculation of an absorbent capable of reducing energy consumption by recirculating the absorbent, from which acid gas has been pre-separated, to an absorption tower before supplying the absorbent to the regeneration tower in an acid gas capture system.
