摘要: In a production method for oxygen, liquid oxygen is taken out from a rectification column of an air separation unit, and is compressed by a pump so that the pressure thereof exceeds the critical pressure. Then, the oxygen is led into a heat exchanger and is heated therein so that the temperature of the oxygen exceeds the critical temperature.
