The easiest way is to compress the air until it liquefies. Then you can seperate the Nitrogen by distillation. It has a different boiling point than oxygen and the other components of air.
Since air is 80% nitrogen, this is a very practical way to isolate it.

Depending on the purity that you need, gas that is almost all nitrogen is a byproduct of the process of liquefying air to get commercial grade welding oxygen. What is left is almost all nitrogen. Nitrogen has commercial value as am inert cover for flammables.
If you really wanted to get very pure nitrogen by removing the argon, carbon dioxide, and other small components out from the air then the liquefied nitrogen-rich liquid could be fractionally distilled. Do that by slowly warming it up to get each unwanted gas to boil off at its unique boiling point temperature.

I don't get what you mean by that. You mean there is a technique to separate it? Well, nitrogen being the most abundant gas in the atmosphere I suppose there might be a way but I've never heard of it. Plants fix it though in order to use it....
