Removing CO2 from a brathing loop
Removing CO2 from a brathing loop
(OP)
What I would like to do is be able to remove CO2 from a Helium Oxygen Nitrogen breathing mix without relying on a sodalime chemical scrubber. can anyone on this site help me. Expired gas would be approx 5% CO2 on every breath. approx 1 liter per minute





RE: Removing CO2 from a brathing loop
There has been work with possible commercialization on membrane contactors, with a membrane between the base and the gas stream. The system I have some knowledge of uses amines not soda lime. It was being projected for large scale natural gas operations, so it may also be a dead end.
