Industrial Oxygen: Its Use and Generation
Know More

The idea behind the process is to lower the temperature of the air such that nitrogen and oxygen separate based on their boiling points This occurs at around - 300oF If higher purity oxygen or liquid oxygen is required, further distillation is required For liquid oxygen, nitrogen is used as the heat transfer fluid to further cool the oxygen...
