## nitrogen helium capacity

• ### Process Technologies for Helium Recovery from Natural

The nitrogen-rich feed is compressed to 2 bar and upgraded by cooling to 80 5 K in the first nitrogen removal stage where part of the nitrogen is condensed to give a helium-enriched stream of 26 % The gas is then warmed to ambient temperature compressed to 31 bar and mixed with air to feed the hydrogen oxidation reactor

• ### Helium versus nitrogen – Copenhagen Suborbitals

One of the goals of the tests was to determine whether we can use nitrogen as pressurising gas instead of helium Economically it is very advantageous to use nitrogen rather than helium as a bottle of helium containing 10 000 liters cost us 2 000 kroner (approx 285 USD) whereas the same amount of nitrogen cost us 150 kroner (approx 22 USD)
