separation of oxygen from liquid acs
Answers
Answer:
Oxygen can be separated from liquid air through fractional distillation.
Explanation:
(Hope there is a typo error in the question. Reading the question as 'Separation of oxygen from liquid air'.)
Air which is initially in gas phase turns into liquid phase when cooled around -200°C.
Air contains many gases like carbon di-oxide, water vapors, oxygen, nitrogen, etc.,
Different elements in the air have varied boiling points and thus can be distilled separately.
Initially, water vapors and carbon di-oxide are removed from it.
Boiling point of nitrogen is -196° C. When the liquid air is heated at a temperature above -196°C, then nitrogen will become vapor.
Later, the left out oxygen is converted into vapor at its boiling point -183° C and distilled separately.
Explanation:
The fractional distillation method is used to separate Oxygen from Liquid air. Liquid Oxygen is having a soaring popularity among many industries that produce food, medicine etc. In the fractional distillation method, they aim to liquefy the air by cooling it until it reached -200 degrees celcius. The air that is comprised of components like nitrogen, oxygen and carbon di oxide, undergoes different boiling points. The liquid air is heated to the point of turning into gas from liquid. They them filter the air through filters to rid it of dust and other contaminants and the cooled in different stages until carbon-di-oxxide becomes solid and starts to drop from the cooled air leaving Nitrogen, Oxygen and argon in the air.
