Question

based on what principle components of air are separated. give 3 examples ​

Answer 1

The answer to the following question is as follows :

- Based on the principle of fractional distillation the primary components of air , i.e, nitrogen and oxygen are separated.

- A thermal process named as cryogenic rectification is implemented by the air fractioning plants for the process of separation.

- Further this process separates the individual components from each other so that highly purified gases of (nitrogen , oxygen, argon) can be produced in liquid form.

Answer 2

Principles that separate the components of air:

1. Cryogenic distillation:

• It is a process occurs at low temperature which operates at low boiling point relative to the feed components.
• The air is liquefied to separate gases.
• This is used to produced propellants of the rocket and liquification of natural gas.

2. Pressure swing adsorption:

• This process operates at certain pressure and ambient temperature.
• The pressure depends on the adsorbent material.

3. Vacuum pressure swing adsorption:

• It is a non-cryogenic gas separation technique.
• The vacuum plays a wide role as a adsorbent.
