ABSTRACT:
Oxygen gas is produced at greater than atmospheric pressure by separating air into oxygen-rich and nitrogen-rich fractions in a distillation column, removing the oxygen as liquid and pumping it to the desired pressure and subsequently vaporizing the pumped liquid oxygen by means of energy absorbed from a recirculation argon containing fluid.
