Which materials are required for seperation of gases from air​

Answer»

Answer:

Precooling of air - To separate air into its components, it must first be liquefied at an extremely LOW temperature. As a first step, the COMPRESSED air is precooled with chilled water. Purification of air - IMPURITIES such as water vapour and carbon dioxide are then removed from the air in a so-called MOLECULAR sieve.
