Question

some more information about separation of the components of the air​

Answer 1

Answer:

An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases.

The most common method for air separation is fractional distillation. Cryogenic air separation units  are built to provide nitrogen or oxygen and often co-produce argon. Other methods such as membrane, pressure swing adsorption  and vacuum pressure swing adsorption  are commercially used to separate a single component from ordinary air. High purity oxygen, nitrogen, and argon used for semiconductor device fabrication requires cryogenic distillation. Similarly, the only viable source of the rare gases neon, krypton, and xenon is the distillation of air using at least two distillation columns.
