Principle of nitrogen-making machine system
- Aug 29, 2018 -

Oxygen, nitrogen two gas molecules on the molecular sieve surface diffusion rate is different, small diameter gas molecules (O2) diffusion rate is faster, more into the carbon molecular sieve microporous, larger diameter gas molecules (N2) diffusion rate is slow, into the carbon molecular sieve micro-pore less. The selective adsorption of nitrogen and oxygen by carbon molecular sieve is different, which leads to the enrichment of oxygen in a short time, the enrichment of nitrogen in gas phase, the separation of oxygen and nitrogen, and the gas-phase enrichment of nitrogen under the PSA condition.
