A carbon dioxide (CO2) adsorption membrane or bed is operative to separate metabolic CO2from an exhaust stream from a breathable atmosphere which is discharged from a closed habitable environment. The habitable environment is in a low ambient pressure surrounding. A portion of the scrubbed exhaust gas stream is diverted from the habitable environment and passed through a desorption chamber. The desorption chamber is open to the low ambient pressure surrounding to maintain a pressure which is slightly greater than the pressure in the ambient surrounding so that the desorption chamber gas stream will exit the system into the ambient surroundings. When the diverted exhaust gas enters the low pressure desorption pressure chamber its CO2partial pressure content is reduced. The reduced CO2partial pressure content of the gas stream in the desorption chamber enables the desorption chamber gas stream to remove CO2from the adsorption membrane or bed.
