  2. 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 ...

  3. Matheson (compressed gas & equipment) - Wikipedia

    en.wikipedia.org/wiki/Matheson_(compressed_gas...

    Specialty Gases and Equipment, including high purity gas, gas mixtures, environmental gas calibration standards, EPA Protocol Gases, and associated hardware and services – primarily serving the laboratory, process, and environmental gas user and other specialties. HyCO (Hydrogen, Carbon Monoxide) plant engineering, construction and operation ...

  4. Nitrogen generator - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_generator

    High nitrogen purity: PSA nitrogen generator plants allow production of high-purity nitrogen from air, which membrane systems are unable to provide – up to 99.9995% nitrogen. But in most cases they do not produce more than 98.8% nitrogen with the remainder being argon that is not separated from the nitrogen by the usual PSA process.

  5. Industrial gas - Wikipedia

    en.wikipedia.org/wiki/Industrial_gas

    A gas regulator attached to a nitrogen cylinder. Industrial gases are the gaseous materials that are manufactured for use in industry.The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders.

  6. Schlenk line - Wikipedia

    en.wikipedia.org/wiki/Schlenk_line

    An explosion can occur due to the common use of liquid nitrogen in the cold trap, used to protect the vacuum pump from solvents. If a reasonable amount of air is allowed to enter the Schlenk line, liquid oxygen can condense into the cold trap as a pale blue liquid.

  7. Membrane gas separation - Wikipedia

    en.wikipedia.org/wiki/Membrane_gas_separation

    The membrane gas separation equipment typically pumps gas into the membrane module and the targeted gases are separated based on difference in diffusivity and solubility. For example, oxygen will be separated from the ambient air and collected at the upstream side, and nitrogen at the downstream side.

  8. Pressure swing adsorption - Wikipedia

    en.wikipedia.org/wiki/Pressure_swing_adsorption

    With this variant of PSA developed for use in laboratory nitrogen generators, nitrogen gas is produced into two steps: in the first step, the compressed air is forced to pass through a carbon molecular sieve to produce nitrogen at a purity of approximately 98%; in the second step this nitrogen is forced to pass into a second carbon molecular ...

  9. Medical gas supply - Wikipedia

    en.wikipedia.org/wiki/Medical_gas_supply

    Medical oxygen storage tanks at the Royal Women's Hospital, Melbourne, Australia. Oxygen may be used for patients requiring supplemental oxygen via mask. Usually accomplished by a large storage system of liquid oxygen at the hospital which is evaporated into a concentrated oxygen supply, pressures are usually around 345–380 kPa (50.0–55.1 psi), [1] [2] or in the UK and Europe, 4–5 bar ...
