  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. Liquid-hydrogen tank car - Wikipedia

    en.wikipedia.org/wiki/Liquid-hydrogen_tank_car

    The pressure within the tank is 25 psi (170 kPa) or lower [3] [4] with a temperature below 20.27 K (−423.17 °F or −252.87 °C) and a boil-off rate of 0.3% to 0.6% per day [5] The tank is double walled like a vacuum flask with multi-layer insulation, with the valves and fittings enclosed in a cabinet at the lower side or end of the car.

  4. Cryogenics - Wikipedia

    en.wikipedia.org/wiki/Cryogenics

    Nitrogen is a liquid under −195.8 °C (77.3 K).. In physics, cryogenics is the production and behaviour of materials at very low temperatures.. The 13th International Institute of Refrigeration's (IIR) International Congress of Refrigeration (held in Washington DC in 1971) endorsed a universal definition of "cryogenics" and "cryogenic" by accepting a threshold of 120 K (−153 °C) to ...

  5. Hydrogen storage - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_storage

    For many years hydrogen has been stored as compressed gas or cryogenic liquid, and transported as such in cylinders, tubes, and cryogenic tanks for use in industry or as propellant in space programs. The overarching challenge is the very low boiling point of H 2 : it boils around 20.268 K (−252.882 °C or −423.188 °F).

  6. Liquid-hydrogen trailer - Wikipedia

    en.wikipedia.org/wiki/Liquid-hydrogen_trailer

    The U-1 semi-trailer was a liquid-hydrogen trailer designed in the 1950s to carry cryogenic liquid hydrogen (LH 2) on roads being pulled by a powered vehicle.It was constructed by the Cambridge Corporation and had a capacity of 26,000 liters (6,900 U.S. gal; 5,700 imp gal) with a hydrogen loss rate of approximately 2 percent per day.

  8. Cryogenic fuel - Wikipedia

    en.wikipedia.org/wiki/Cryogenic_fuel

    Cryogenic fuels are fuels that require storage at extremely low temperatures in order to maintain them in a liquid state. These fuels are used in machinery that operates in space (e.g. rockets and satellites) where ordinary fuel cannot be used, due to the very low temperatures often encountered in space, and the absence of an environment that supports combustion (on Earth, oxygen is abundant ...
