US Patent 11577222 Carbon dioxide capture

A carbon dioxide containing fluid is flowed through a membrane in an open position. The membrane encapsulates an adsorbent bed operating at a first temperature. The adsorbent bed adsorbs at least a portion of the carbon dioxide of the carbon dioxide containing fluid. The membrane is adjusted to a closed position, thereby isolating the adsorbent bed and preventing fluid flow into and out of the membrane. The adsorbent bed is heated to a second temperature, thereby desorbing the carbon dioxide captured from the carbon dioxide containing fluid. The membrane is adjusted to the open position. The adsorbent bed is cooled to the first temperature.
