Main types of industrial nitrogen production:
First, membrane air separation to produce nitrogen
Using air as raw material, gases such as oxygen and nitrogen are used under pressure conditions with different permeation rates in the membrane to separate oxygen and nitrogen.
Second, cryogenic air separation nitrogen production
Cryogenic air separation nitrogen production is a traditional nitrogen production method. It uses air as raw material, compresses, purifies, and then uses heat exchange to make the air into a liquid state. It is mainly a mixture of liquid oxygen and liquid nitrogen, using the different boiling points of liquid oxygen and liquid nitrogen, and after the distillation process, they are separated to obtain nitrogen.
Third, molecular sieve nitrogen production
Using air as raw material, carbon molecular sieve as adsorbent, using the principle of pressure swing adsorption, using carbon molecular sieve to selectively adsorb oxygen and nitrogen to separate nitrogen and oxygen, commonly known as PSA nitrogen production.
