DBMN Model Selection Table of Membrane Separation Nitrogen
Principle
Under pressure, when two or more gas mixtures pass through a polymer fiber membrane, the relative permeation rate of different gases in the membrane group varies due to the differences in solubility and diffusion coefficient of various gases in the membrane. Based on this characteristic, we refer to gases with high permeation rates as "fast gases", and gases with low permeation rates as "slow gases". When the mixed gas is driven by the pressure difference on both sides of the membrane separator, "fast gas" such as water, oxygen, carbon dioxide, etc. penetrate the membrane wall and are enriched on the membrane permeation
side, while "slow gas" such as nitrogen, carbon monoxide, argon, etc. are enriched on the retention side, thus achieving the purpose of mixed gas. When pressurized purified air is used as the gas source, inert gases such as nitrogen are enriched into high-purity gases for production applications, and oxygen rich air is discharged from the permeation side. Oxygen rich air can be obtained on the permeation side of the nitrogen membrane system, with an oxygen rich concentration of 30-40%. If you need to use its oxygen rich air, you can consult our company.
