Title:
CARBON DIOXIDE CAPTURE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/013957
Kind Code:
A1
Abstract:
A carbon dioxide capture system according to the present disclosure includes a supply path, a carbon dioxide adsorption unit having a processing region and a regeneration region, an extraction path, a regeneration path, a circulation path, and a carbon dioxide separator. The supply path guides air. In the processing region, an adsorbent is made to adsorb carbon dioxide contained in the air. In the regeneration region, the adsorbent is regenerated using a regeneration fluid. The extraction path guides the air of which the carbon dioxide concentration has been reduced in the processing region. The regeneration path guides the regeneration fluid to the regeneration region. The circulation path guides a regeneration discharge fluid discharged due to the regeneration of the adsorbent by the regeneration fluid. The carbon dioxide separator obtains the regeneration fluid by separating at least some of the carbon dioxide from the regeneration discharge fluid.
