By cooling and pressing air and then expanding it you can separate liquid nitrogen from air.
AnswerThe air must be repeatedly cooled and compressed until it liquefies. The liquid air is then fractionated (allowed to evaporate under controlled conditions) so that each component (oxygen, nitrogen, argon) is released as a pure stream. The Nitrogen stream is collected and re-cooled to be a liquid for storage and handling as the volume of the liquid is much less than the gaseous nitrogen.

How can you get nitrogen out of the air?
by fractional liquefaction, you separate various gasses from air by the temperature they liquify.
How do you chemically separate oxygen from air?
Oxygen from air is separated by first condensing it into a liquid and then using fractional distillation to separate nitrogen and other gases. That is the only way to separate oxygen from air on industrial scale.
How does nitrogen separate to be useful?
Nitrogen is an element, it does not separate smaller than nitrogen atoms, unless you consider subatomic particles to be useful,
Could distillation be used to separate air into oxygen nitrogen argon etc?
Yes. That is how argon is produced on a commercial basis.
How do producers get nitrogen?
Nitrogen occurs naturally in our atmoshere. It is 78 percent of the air around us. To separate it from the oxygen and other inert gasses manufactures heat pressurized air. As it heats, the oxygen and other gases which are more suceptable to heat, boil off leaving the nitrogen behind.

How can nitrogen be retrieved from air?
One way is to liquify air using high pressure and low temperature, then fractional distillation to separate the air into its components, including nitogen.

Does nitrogen contain air?
Nitrogen doesn't contain air, but the air contains Nitrogen.
Could distillation be used to separate air into oxygen nitrogen argon etc?
Yes. That is how argon is produced on a commercial basis.

Is nitrogen in air?
Yes. About 75% of air is Nitrogen.
What percentage of nitrogen is their in your air?
About 78% of air is Nitrogen.
How much nitrogen is there in the air?
There is about 78.09% of nitrogen in the air.
What is the percent if the air is nitrogen?
Our air is about 79% Nitrogen.
How much of nitrogen is in the air you breathe?
Air is 78% Nitrogen
