CPN-M membrane separation nitrogen generation equipment
CPN-M membrane separation nitrogen generation equipment
Membrane separation is one of the most advanced air separation technologies in the world. The principle is to achieve the purpose of nitrogen and oxygen separation by using the difference of permeation rate of each component gas in the air passing through the separation membrane. The schematic diagram is shown on the right:
Advantages of nitrogen making membrane
◎The separation membrane is made of the most advanced polyimide (PI) hollow fiber.
◎Wide temperature range of separation membrane: 3-90 ℃.
◎Wide range of operating pressure: 0.3MPa ～ 10MPa.
◎High separation coefficient, large gas volume and high recovery.
◎Good chemical and physical stability.
◎Long service life, generally up to 10 years.
◎High efficiency, low cost, small volume and light weight.
◎The purity of nitrogen can be adjusted by 90% – 99.9%.
◎Strong adaptability to ambient temperature: – 20 ~ 45 ℃
