Membrane separation nitrogen generator manufacturer

Membrane separation nitrogen equipment: membrane separation nitrogen technology According to the pressure difference on both sides of the membrane, the solubility and diffusion coefficient of nitrogen and oxygen in the air are different in the membrane. Some gases (such as water vapor and highly permeable oxygen) first penetrate the membrane and become oxygen-rich gases. The slower nitrogen rate will become a dry nitrogen-rich gas, which will remain concentrated for the purpose of separating oxygen and nitrogen.

BMN Membrane Separation Nitrogen Generator — Usually all gases can penetrate through the polymer membrane, the process is that the gas molecules are first adsorbed and dissolved in the high pressure surface of the membrane, and then diffused in the membrane with the help of the concentration gradient, and finally resolved from the low pressure side of the membrane, the result is that small molecules and molecules with strong polarity (such as water vapor, oxygen, carbon dioxide, etc.) pass faster and are enriched on the permeable side of the membrane. However, macromolecules and molecules with weak polarity (such as nitrogen, oxygen, etc.) pass slowly and are trapped on the retention side of the membrane to be enriched to achieve the purpose of mixed gas separation. Membrane separation is the use of various gases in the polymer membrane penetration rate is different, to carry out gas separation, the separation driving force is the partial pressure difference of the gas on both sides of the membrane, so the membrane method of gas separation does not phase change, does not need to regenerate, has the advantages of simple equipment, low operation and maintenance costs. A membrane separator (component) is composed of thousands of hollow fiber separation membrane assembled in a shell, its structure is similar to a tubular heat exchanger, it can provide the largest separation membrane surface area in the smallest space, so the membrane separation system has the advantages of small footprint, light weight, convenient expansion and so on.
