Cryogenic plants for nitrogen, oxygen and argon production
GRASYS cryogenic systems designed for complex recovery of air separation products allow commercial production of gases such as nitrogen, oxygen, and argon at minimum production costs.
The plants designed for generation of several gases from air appear the first choice in the cases where an enterprise has a multiple-gas process flow. Cryogenic technology is the only air separation technology enabling production of high-purity atmospheric gases. Cryogenic systems are used to produce gases with the purity of as high as 99.9999% for nitrogen, 99.95% for oxygen, and 99.9999% for argon.
Another advantage of cryogenic plants is their capability to produce nitrogen, oxygen, and argon in two aggregative states: gaseous and liquid. Alternative technologies, such as membrane and adsorption, allow to produce only gaseous air separation products.
