  • Patent number: 12172123
    Abstract: A system and method for, removing carbon dioxide from a carbon dioxide laden gas mixture, the system comprising a group of carbon dioxide removal structures moving along a closed curve track. At one location along the track is located a desorption or regeneration box, into which each capture structure passes in order to be regenerated. The majority of the CO2 removal structures are fed ambient air, or an admixture of ambient air with a minor portion of a flue gas, and exhaust CO2-lean air. At least one selected such removal structure within each group, at a location immediately preceding its entry into the capture structure, is fed a flue gas comprising at least 4% CO2 by volume. A method for removing carbon dioxide from the atmosphere is provided utilizing a system operating in the same manner as the preceding system.
