Fractional Distillation of Liquefied Air
- Nitrogen gas (N2) is commercially prepared by the fractional distillation of liquefied air.
- In this process, air is liquefied and then slowly heated up in a fractional distillation column.
- Different components of air have different boiling points, allowing them to be separated as the temperature increases.
- Nitrogen has a boiling point of -196°C, which is lower than that of oxygen and other gases present in air.
- As a result, nitrogen gas vaporizes first and can be collected separately, providing a source of pure nitrogen gas.
By following this method, large quantities of nitrogen gas can be produced for various industrial applications.
