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.
Oxygen tanks containing pressures of up to 200 bar (3000 psi) are used for industrial processes including the manufacturing of steel and monel, welding and cutting, medical breathing gas, diving and as an emergency breathing gas in aircraft. A small steel tank of 16 litres water capacity with a working pressure of 139 bar (2015 psi), holds ...
Industrial gases are the gaseous materials that are manufactured for use in industry. (The industry producing these gases is also known as industrial gas, which is seen as also encompassing the supply of equipment and technology to produce and use the gases.)
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 ...
Ozone generators sold as air cleaners intentionally produce the gas ozone. [43] These are often marketed to control indoor air pollution, and use misleading terms to describe ozone. Some examples are describing it as "energized oxygen" or "pure air", suggesting that ozone is a healthy or "better" kind of oxygen. [43]
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.
Lean air is a gas mixture with an oxygen content lower than 20.95% (the oxygen content of the normal breathing air).Lean air is made from a gas mixture of air with nitrogen or of pure oxygen with nitrogen and is used in several production processes where a product covering with pure nitrogen can be dangerous, undesirable or more expensive.
It is also shipped as a liquid in Dewar type vessels (like a large Thermos jar) to places that use large amounts of oxygen. It is also possible to separate oxygen from air by passing the air, under pressure, through a zeolite sieve that selectively adsorbs the nitrogen and lets the oxygen (and argon) pass. This gives a purity of oxygen of about ...
