2. Oxygen scavenger - Wikipedia

   en.wikipedia.org/wiki/Oxygen_scavenger

   An oxygen absorber The contents of an oxygen absorber from a packet of beef jerky. Oxygen scavengers or oxygen absorbers are added to enclosed packaging to help remove or decrease the level of oxygen in the package. They are used to help maintain product safety and extend shelf life. [1] There are many types of oxygen absorbers available to ...

3. Oxygen concentrator - Wikipedia

   en.wikipedia.org/wiki/Oxygen_concentrator

   As the first cylinder reaches near pure oxygen (there are small amounts of argon, CO 2, water vapour, radon, and other minor atmospheric components) in the first half-cycle, a valve opens and the oxygen-enriched gas flows to the pressure-equalizing reservoir, which connects to the patient's oxygen hose. At the end of the first half of the cycle ...

4. 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.

5. Pressure swing adsorption - Wikipedia

   en.wikipedia.org/wiki/Pressure_swing_adsorption

   VSA differs from other PSA techniques because it operates at near-ambient temperatures and pressures. VSA typically draws the gas through the separation process with a vacuum. For oxygen and nitrogen VSA systems, the vacuum is typically generated by a blower. Hybrid vacuum pressure swing adsorption (VPSA) systems also exist.

6. Oxygen storage - Wikipedia

   en.wikipedia.org/wiki/Oxygen_storage

   Most humans can function at rest with an oxygen level of 15% at one atmosphere pressure; [1] a fuel such as methane is combustable down to 12% oxygen in nitrogen. A small room of 10 meter 3 has 2.08 meter 3 (2080 liters) or 2.99 kg of oxygen which would occupy 2.62 liters if it was liquid.

7. High altitude breathing apparatus - Wikipedia

   en.wikipedia.org/wiki/High_altitude_breathing...

   Bottled oxygen, more broadly known as high pressure compressed oxygen, medical oxygen, and aviator's oxygen, is oxygen in small, portable, high-pressure storage cylinders. For aviation, the weight of the cylinder is usually not critical, and the choice of material may be affected by economic considerations such as purchase price and useful ...
