Abstract
Provided is an apparatus for regenerating a carbon dioxide absorption solution that regenerates an absorption solution for absorbing carbon dioxide contained in a combustion exhaust gas emitted during a combustion process of a vehicle, thereby reducing energy costs while simplifying its configuration. The apparatus includes a first storage tank for storing an absorption solution that contains absorbed CO2; a regeneration column for generating an absorption solution regenerated by heating the absorption solution to free/release CO2; a separation drum for separating the CO2 freed/released during the regeneration; a multi-stepped compressor for compressing the separated CO2; a heat exchanger for performing a heat exchange between the absorption solution discharged from the first storage tank and the CO2 compressed in the multi-stepped compressor; a temperature sensor for detecting temperature of the absorption solution after the heat exchange in the heat exchanger; and a flow meter for controlling a flow rate of the absorption solution passing through the heat exchanger according to the temperature of the absorption solution detected by the temperature sensor.
