Membrane Separation Nitrogen Generation Principle
The membrane separation nitrogen generation technology is the most advanced air separation technology under the normal temperature in the world at present. Its principle is to utilize the permeation rate difference of different gases in the air at the time of passing through the separation membrane, to achieve the separation of nitrogen and oxygen. The schematic diagram is shown in the right figure.
Nitrogen Separation/Ideal System Process
Advantages of the Membrane for Nitrogen Generation
1.The separation membrane is made of the most advanced polyimide (PI) hollow fiber.
2.The separation membrane has wide applicable temperature range of 5〜8CTC.
3.Wide Operating Pressure Range: 0.3MPa〜20MPa.
4.Have high separation factor, large product gas volume, and high recovery rate.
5. Own excellent chemical & physical stability.
6.The service life may reach 10 years.
7. Have high efficiency, low cost, small volume and light weight.
8.The nitrogen purity is adjustable in the range of 90%~99.9%.
9.Own strong adaptability for environmental temperature of -40〜12CTC.
