General information
Cryogenic technology is the optimum choice for large-scale oxygen consumption. Normally, with the consumption volume exceeding 1,000 nm³/hr, cryogenic plants appear the most preferable due to their cost efficiency.
Another advantage of cryogenic oxygen plants is the optional oxygen production in two aggregate states: gaseous and liquid. While the alternative, membrane and adsorption, technologies allow producing gaseous oxygen only.
