Question

5. a. Explain how, nitrogen, oxygen and argon gases are separated from air.
b. Draw a flow diagram of the process involved in obtaining gases like
nitrogen, oxygen and argon from air.​

Answer 1

Answer:

a) Nitrogen, oxygen and argon are separated from air by fractional distillation. ... This liquid air is then fed into a fractionating column from its bottom end and is cooled slowly. Liquid nitrogen boils off first to nitrogen gas as the boiling point of nitrogen is lowest at -196°C.

b) 78% of the nitrogen in the atmosphere and oxygen is 21% other gases like 1% like argan etc

Answer 2

nitrogen and oxygen separated from air by fractional distillation .

and I can't draw a diagram by my keyboard
