Couldn't this also be done for the other reactive components (especially nitrogen and oxygen) before cooling the gas? Removing ~99% of the mass ahead of time would require that much less energy for cooling.
- londons_explore 8y agoLiquid oxygen and nitrogen both have some commercial value. The tricky but is the liquidation process only liquifies some small fraction of the gas. The rest remains as a gas, so you now have "helium enriched" air, but it is still a very small percentage helium.
