CARBON DIOXIDE CAPTURING APPARATUS AND CAPTURING METHOD

WIPO Patent Application WO/2023/105507

A1

One embodiment of a carbon dioxide capturing apparatus according to the present invention comprises: an absorption column comprising a carbon dioxide adsorption part or carbon dioxide absorption part for adsorbing or absorbing carbon dioxide from an exhaust gas; a regeneration column connected to the absorption column and comprising an adsorbent heating part, which is for heating an adsorbent circulating the inside thereof, and an absorbent heating part which is for heating an absorbent circulating the inside thereof; and the adsorbent or absorbent circulating the absorbent column and the regeneration column to alternately perform adsorption and desorption of carbon dioxide or absorption and desorption of carbon dioxide. The carbon dioxide capturing apparatus is characterized in that: a line is branched from a first dynamic-pressure gas line connecting a line, for carbon dioxide desorbed in the regeneration column, and an absorption column hopper, so as to supply a low density oxygen gas to the absorption column hopper; and a line is branched from a second dynamic-pressure gas line connecting a line, for discharging a carbon dioxide-removed exhaust gas to the outside through the upper end of the absorption column, and a regeneration column hopper, so as to supply a low density oxygen gas to the regeneration column hopper.
