Oxygen is most essential for the survival of humans and during the pandemic of Covid-19, has caused the scarcity of oxygen cylinders for Hospitals in India in 2021.Oxygen used for patients has various specifications as the lives of them depend upon that oxygen. The Industrial way of producing oxygen is by various methods. Cryogenic separation is the one that gives the purest oxygen (>99.5%). A cryogenic air separation unit (ASU) is an old process used to produce high purity oxygen or nitrogen at high volumes. The modified process for small scale oxygen production is given as, Air is compressed by isothermal compressor at a pressure of 20 bar with temperature rise upto 90 ℃. After compressore air is received by the cooler where the temperature is dropped to 0 ℃ . The coolant used in cooler is 50% water 50% ethylene glycol mixture. After cooler air is passed through turboexpander. Pressure of air is reduced to 2 bar by increasing the volume of air. By simulation study we obtained 98% purity of oxygen with the approximate flowrate of 77 gm/ sec(2 tons per day)
