CARBON-DIOXIDE CAPTURE AND TREATMENT SYSTEM AND CARBON-DIOXIDE NEGATIVE EMISSION PLANT
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. The carbon-dioxide capture and treatment system is operable to treat carbon dioxide generated inside a plant entirely within the plant, without emitting the carbon dioxide to the outside of the plant, and to take in air contained in an ambient environment and subject the intake air to the same treatment as that for emission gas from the plant, so that it is possible to allow carbon dioxide emissions from the plant to the outside to have a negative value.
