Cryogenic plants for nitrogen, oxygen and argon production
The cryogenic systems for complex recovery of air separation products offered by GRASYS allow arranging for commercial production of such gases as nitrogen, oxygen and argon at the minimum production cost.
The plants designed for recovery of several gases from the air are primarily required at facilities using several gases in their process flows. Cryogenic technology is the only air separation technology used to produce high-purity atmospheric gases. Cryogenic systems allow producing nitrogen with purity up to 99.9999%, oxygen with purity up to 99.95% and argon with purity up to 99.9999%.

General informationThe advantage of cryogenic plants lies in their capability of producing nitrogen, oxygen and argon in two aggregate states: gaseous and liquid. While the alternative technologies, membrane and adsorption, are capable of producing gaseous air separation products only. Basic technical characteristics of cryogenic plants
