How is oxygen produced?
Until now, the best and least expensive way to produce pure oxygen is to use the ambient air. The procedure for producing pure oxygen is that first the ambient air is taken from the environment with the help of very powerful compressors and then the compressed air is taken into the turbines. These turbines cool the air to a temperature of 190 °C. Cooling the gas causes the initial air to turn into a liquid, then this liquid is introduced into the separating parts to be stored in separate tanks after separation.
The temperature of liquid oxygen is very low and around 183°C. Since liquid oxygen occupies less space, more volume can be produced. Tanks that store separated liquids can store liquids for a long time.
