Question

explain the procedure of fractional distillation for separating oxygen from air​

Answer 1

Answer:

Air is filtered to remove dust, and then cooled in stages until it reaches –200°C. At this temperature it is a liquid.

...

Liquefying the air

water vapour condenses , and is removed using absorbent filters.

carbon dioxide freezes at -79°C, and is removed.

oxygen liquefies at -183°C.

nitrogen liquefies at -196°C.

Answer 2

Step-by-step explanation:

the liquid nitrogen and oxygen are then separated by fractional distillation the liquefied air is passed into the bottom of the frictional addition column just as in the column used to separate oil actions in the volume of warmer at the bottom then it is at the top
