  2. 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.

  3. Pressure swing adsorption - Wikipedia

    en.wikipedia.org/wiki/Pressure_swing_adsorption

    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. VPSA systems apply pressurized gas to the separation process and also apply a vacuum to the purge gas.

  4. Cryogenic gas plant - Wikipedia

    en.wikipedia.org/wiki/Cryogenic_gas_plant

    A cryogenic gas plant is an industrial facility that creates molecular oxygen, molecular nitrogen, argon, krypton, helium, and xenon at relatively high purity. [1] As air is made up of nitrogen, the most common gas in the atmosphere, at 78%, with oxygen at 19%, and argon at 1%, with trace gasses making up the rest, cryogenic gas plants separate air inside a distillation column at cryogenic ...

  5. Oxygen plant - Wikipedia

    en.wikipedia.org/wiki/Oxygen_plant

    The complexes are rated to 5 to 5,000 nm3/hr of oxygenated air. [1] In the membrane oxygen plant, gas separation is achieved in the gas separation module composed of hollow-fiber membranes and representing the plant critical and high-technology unit. Apart from the gas separation unit, other important technical components are the booster ...

  6. Hampson–Linde cycle - Wikipedia

    en.wikipedia.org/wiki/Hampson–Linde_cycle

    Linde's 1895 patent.. The Hampson–Linde cycle is a process for the liquefaction of gases, especially for air separation. William Hampson and Carl von Linde independently filed for patents of the cycle in 1895: Hampson on 23 May 1895 and Linde on 5 June 1895.

  7. Direct air capture - Wikipedia

    Flow diagram of direct air capture process using sodium hydroxide as the absorbent and including solvent regeneration An example of what Direct Air Capture could look like and how the process works. Direct air capture (DAC) is the use of chemical or physical processes to extract carbon dioxide (CO 2) directly from the ambient air. [1]

  9. Gas centrifuge - Wikipedia

    en.wikipedia.org/wiki/Gas_centrifuge

    Diagram of a gas centrifuge with countercurrent flow, used for separating isotopes of uranium. A gas centrifuge is a device that performs isotope separation of gases. A centrifuge relies on the principles of centrifugal force accelerating molecules so that particles of different masses are physically separated in a gradient along the radius of a rotating container.
