Abstract

Provided is a carbon-dioxide capture and treatment system comprising: a carbon dioxide-enriched mixture gas generation device comprising a separation membrane capable of increasing a carbon dioxide concentration of a mixture gas taken therein, thereby generating a carbon dioxide-enriched mixture gas; a carbon dioxide conversion device configured to convert carbon dioxide in the enriched mixture gas received from the carbon dioxide-enriched mixture gas generation device, into a chemically stable compound; a final treatment device comprising an adsorbent, wherein the final treatment device is configured to adsorb the carbon dioxide by the adsorbent, thereby separating the carbon dioxide from other gas components; and a carbon dioxide direct capture device configured to take in air contained in an ambient environment, and supply the taken-in air to the final treatment device or an upstream side thereof in the carbon-dioxide capture and treatment system.
