Jul 20, 2013 Cryogenic air separation process is an energy intensive, low-temperature process which separates air into its component gases. Energy consumption of oxygen separation is an increasing function of oxygen purity. The cost of electric energy is the largest single operating cost incurred in air separation plants.
