How can gases in the air be separated

Carbon Dioxide Rare Gases While some cryogenic plants do not bother to further separate rare gases like neon, krypton, and xenon, the technology is the same, simply requiring more purification steps. Neon has a significantly lower boiling point than nitrogen This affects the amount of cooling necessary and order of separation.

Neon Neon is expensive because of its rarity. Like argon, neon is inert, but most applications that take advantage of that trait preferentially choose the much less expensive argon before neon or krypton and xenon, for that matter. Neon emits a reddish-orange glow in electrically induced visible light discharge and is most widely known for the signs that bear its name, even if it is not the only gas that can be used. Neon is also used in a wide variety of vacuum tubes and lasers, as well as serving as an extremely low temperature refrigerant.

Krypton Like neon, krypton is rare, and hence, valuable. It has emission spectra that appears very white, meaning krypton bulbs are prized for photography. Sage Thermal Mass Flow Meters are an excellent choice for measuring the gases, especially given their wide turndown and reproducibility.

Air Separation Gases. Industrial Uses of Oxygen Whether nitrogen or oxygen, flow meters are needed to verify consumption, identify excessive usage or sub metering the air separation gases. Industrial Use of Nitrogen Other than nitrogen reacting with oxygen at high temperatures, as in the combustion process, it is inert under normal temperature and pressure.
