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.

Scrubber apparatus for carbon dioxide removal and controlled atmosphere operating method

A controlled atmosphere system for a cargo storage space, the system comprising a separation area for receiving atmospheric gas from the cargo storage space, a gas moving device arranged to move atmospheric gas from the cargo storage space into the separation area to thereby increase a pressure within the separation area, and a molecular sieve arranged in communication with the separation area, such that when the separation area is at an overpressure, selected molecules are vented out of the separation area through the molecular sieve.
