  2. Helium production in the United States - Wikipedia

    en.wikipedia.org/wiki/Helium_production_in_the...

    Helium usually makes up a minuscule portion of natural gas, but can make up as much as 10 percent of natural gas in some fields. A helium content of 0.3 percent or more is considered necessary for commercial helium extraction. [1] In 2012, helium was recovered at 16 extraction plants, from gas wells in Colorado, Kansas, Oklahoma, Texas, and ...

  3. Air separation - Wikipedia

    en.wikipedia.org/wiki/Air_separation

    A nitrogen generator Bottle of 4Å molecular sieves. Pressure swing adsorption provides separation of oxygen or nitrogen from air without liquefaction. The process operates around ambient temperature; a zeolite (molecular sponge) is exposed to high pressure air, then the air is released and an adsorbed film of the desired gas is released.

  4. Helium storage and conservation - Wikipedia

    en.wikipedia.org/wiki/Helium_storage_and...

    Helium storage and conservation is a process of maintaining supplies of helium and preventing wasteful loss. Helium is commercially produced as a byproduct of natural gas extraction. Until the mid-1990s, the United States Bureau of Mines operated a large scale helium storage facility to support government requirements for helium.

  5. Liquefied natural gas - Wikipedia

    en.wikipedia.org/wiki/Liquefied_natural_gas

    The first large-scale liquefaction of natural gas in the U.S. was in 1918 when the U.S. government liquefied natural gas as a way to extract helium, which is a small component of some natural gas. This helium was intended for use in British dirigibles for World War I. The liquid natural gas (LNG) was not stored, but regasified and immediately ...

    Helium also has a very low boiling point (-268.9°C or -452°F), allowing it to remain a gas even in super-cold environments, an important feature because many rocket fuels are stored in that ...

  7. Natural-gas processing - Wikipedia

    en.wikipedia.org/wiki/Natural-gas_processing

    A natural-gas processing plant in Aderklaa, Austria. Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing contaminants such as solids, water, carbon dioxide (CO 2), hydrogen sulfide (H 2 S), mercury and higher molecular mass hydrocarbons to produce pipeline quality dry natural gas [1] for pipeline distribution and final use.
