Types and principles of industrial nitrogen generators

The main types of industrial nitrogen production: First, membrane air separation nitrogen production Using air as raw material, under pressure conditions, gases such as oxygen and nitrogen are used to have different permeation rates in the membrane to separate oxygen and nitrogen.

How does the nitrogen generator make nitrogen?

When the nitrogen generator manufactures nitrogen, due to the different diffusion rates of oxygen and nitrogen gas molecules on the surface of the molecular sieve, the diffusion rate of gas molecules (O2) with a smaller diameter is faster, more enters the micropores of carbon molecular sieve, and the diffusion rate of gas molecules (N2) with larger diameter is slower, and less enters the micropores of carbon molecular sieve. This selective adsorption difference between nitrogen and oxygen by carbon molecular sieve leads to oxygen enrichment in the adsorbed phase and nitrogen in the gas phase in a short period of time, so that oxygen and nitrogen are separated, and the gas phase enrichment nitrogen is obtained under PSA conditions. After a period of time, the adsorption of oxygen by molecular sieve reaches equilibrium, and according to the different characteristics of carbon molecular sieve adsorption capacity of adsorbed gas at different pressures, the pressure is reduced to make carbon molecular sieve release the adsorption of oxygen, which is a process that can be generated. Nitrogen can be collected in this way.
