It is more than a century that oxygen is used for any industrial process. It was used widely but it was not economical for large scale production. Later in 1895, Carl Von Linde invented a new process for producing large quantities of oxygen for industrial use.
Steps of the Process
- Cooling of the air until it becomes liquid.
- Purification of liquid air.
- Separating various components of liquid using different boiling points of each gas.
Air separation plants take atmospheric air and through processes of purification, cleaning, compression, cooling, liquefaction and distillation, separates the air into the gases oxygen, nitrogen and argon.
