Industrial Gases

Industrial gases are pure elements, molecular compounds or mixtures that are gaseous or vaporous at room temperature and pressure. Industrial gases are used for a variety of applications, depending on the type of gas used. For example, uses of oxygen include welding and cutting, oxidation processes for making chemicals and pharmaceuticals, and treatment of wastewater.

The most common industrial gases are oxygen, hydrogen, nitrogen, carbon dioxide, and rare gases such as argon, neon, xenon, and krypton. Rare industrial gases such as argon are commonly used in laser applications. Some industrial gases are highly volatile and need special handling and storage to ensure their safe usage. For example, hydrogen is highly flammable in its gaseous stage and requires careful handling. An industrial gas supplier typically provides all of these types of gases as well as the storage and processing equipment necessary to work with them. Industrial gas equipment includes storage tanks and distribution systems, vaporizers and pressure vessels, liquid carbon dioxide tanks and cryogenic trailers. Industrial gas supply also includes equipment for working with air such as water vaporizers and pneumatic devices.

Industrial gases are commonly used in manufacturing, especially in cutting and welding applications. Acetylene gas is a highly flammable gas used in metal welding and cutting. Acetylene is explosive when mixed with air or oxygen. Acetylene gas can also be used in the production of organic compounds such as neoprene and rubber and may also be pressurized to produce benzene. Oxygen acetylene torches mix oxygen and acetylene gas in controlled amounts to produce an extremely hot flame. Oxy acetylene welding is used to cut steel or weld iron, and can produce a flame as hot as 6300 degrees Fahrenheit. Other cutting devices include carbon dioxide lasers. CO2 laser cutting uses a laser beam focused with a lens to cut materials and is typically used for precision applications such as laser surgery.
