  2. Hydrogen infrastructure - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_infrastructure

    Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure. Hydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, pipeline transport costs are similar to CNG, [9] the technology is proven, [10] however most hydrogen is produced on the place of demand with every 50 ...

  3. Pressure regulator - Wikipedia

    en.wikipedia.org/wiki/Pressure_regulator

    Two-gauge pressure regulator connected to gas cylinder used for breathing gas supply. Pressure regulators are used with diving cylinders for Scuba diving. The tank may contain pressures in excess of 3,000 pounds per square inch (210 bar), which could cause a fatal barotrauma injury to a person breathing it directly. A demand controlled ...

  4. Gas cylinder - Wikipedia

    en.wikipedia.org/wiki/Gas_cylinder

    The valves on industrial, medical and diving cylinders usually have threads or connection geometries of different handedness, sizes and types that depend on the category of gas, making it more difficult to mistakenly misuse a gas. For example, a hydrogen cylinder valve outlet does not fit an oxygen regulator and supply line, which could result ...

  5. Oxy-fuel welding and cutting - Wikipedia

    en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

    Each gas in the system will have each of these three valves. The regulator converts the high pressure gas inside of the tanks to a low pressure stream suitable for welding. Acetylene cylinders must be maintained in an upright position to prevent the internal acetone and acetylene from separating in the filler material. [20]

  6. Paschen's law - Wikipedia

    en.wikipedia.org/wiki/Paschen's_law

    Paschen's law is an equation that gives the breakdown voltage, that is, the voltage necessary to start a discharge or electric arc, between two electrodes in a gas as a function of pressure and gap length.

  7. Methanol reformer - Wikipedia

    en.wikipedia.org/wiki/Methanol_reformer

    A methanol reformer is a device used in chemical engineering, especially in the area of fuel cell technology, which can produce pure hydrogen gas and carbon dioxide by reacting a methanol and water (steam) mixture.

  8. Mechanism of diving regulators - Wikipedia

    en.wikipedia.org/wiki/Mechanism_of_diving_regulators

    The mechanism of diving regulators is the arrangement of components and function of gas pressure regulators used in the systems which supply breathing gases for underwater diving. Both free-flow and demand regulators use mechanical feedback of the downstream pressure to control the opening of a valve which controls gas flow from the upstream ...

  9. Mass flow controller - Wikipedia

    en.wikipedia.org/wiki/Mass_flow_controller

    Internal block diagram. A mass flow controller (MFC) is a device used to measure and control the flow of liquids and gases. [1] A mass flow controller is designed and calibrated to control a specific type of liquid or gas at a particular range of flow rates.
