How to Extract Oxygen from Air

The most common production method is separation of oxygen in “Air Separation Units”. These separate large volumes of gases using the fractional distillation method to produce pure oxygen from atmospheric air. Atmospheric air is first cooled to minus 181° degrees Celsius. Oxygen liquefies at this point.May 6, 2021
