Cryogenic Plants for Nitrogen, Oxygen and Argon production

Large cryogenic plants designed for the complex extraction of nitrogen, oxygen, argon and other gas mixtures from air using low-temperature rectification technology. Cryogenic systems make it possible to produce gases such as nitrogen, oxygen and argon on an industrial scale.

Cryogenic Plants for Nitrogen, Oxygen and Argon production


up to 100,000 m³/h

Nitrogen purity

up to 99.9999%

Oxygen purity

up to 99.95

Argon purity

up to 99.9999%

Multi-gas extraction plants are the most popular when several gases are used in a company's production processes. Cryogenic technology is the only air separation technology capable of producing high purity atmospheric gases. Cryogenic systems produce nitrogen with a purity of up to 99.9999%, oxygen with a purity of up to 99.95%, and argon with a purity of up to 99.9999%.

Another advantage of cryogenic plants for generation of nitrogen, oxygen, and argon is the ability to produce gases in two states: gaseous and liquid. With the alternative technologies (membrane and adsorption), only gaseous air separation products can be obtained.
