Answer 2

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.The easiest way still remains liquefaction, the air is compressed and cooled gradually until the gases start to separate according to their specific characteristics. First of all you will easily separate the nitrogen, wich will remain a gas when the oxygen is in liquid form.
