(a) Birkeland -Eyde process
(a) Birkeland -Eyde process
Dinitrogen is prepared commercially from air by liquification and fractional distillation. When liquid air is allowed to distil, dinitrogen having lower b.pt ($77\,K$) distils over first leaving behind liquid oxygen (bpt $90\,K$). World wide production of dinitrogen from liquid air is more than $50$ million tonns per year.
