Abstract
The disclosure relates to an activated carbon scrubber apparatusand a method of its operation for carbon dioxide (CO) removal from a controlled environment. The scrubber apparatus is configured to switch between: an adsorption configuration in which it is configured to provide CO-rich gas from the controlled environment to a sorbent bedcomprising activated carbon for COadsorption, and to return the treated gas to the controlled environment; and a regeneration configuration in which it is configured to provide a regenerating gas from outside of the controlled environment to the sorbent bed to desorb COand regenerate the activated carbon, and to discharge CO-rich gas outside of the controlled environment. The method comprises alternately operating the scrubber apparatus in the adsorption configuration and the regeneration configuration over a plurality of cycles, wherein the scrubber apparatus is operated at a cycle frequency of between 4 and 30 cycles per hour. A heateris controlled to heat the sorbent bed in the regeneration configuration.
