Energy-saving hollow fiber membrane Nitrogen Generator, patent number: 200720094935.6.

Hollow fiber membrane separation technology is a high-tech developed at the mid-twentieth century. The past two or three decades, the membrane separation technology has been developed rapidly, bring enormous benefits to humanity.
The membranes get the characteristics of selective permeability and spread to a certain gas components, which can achieve the purpose of gas separation.

Hollow fiber membranes are in fact the pores with the same in and outer diameters, similar to the structure of tube heat exchanger. Each fiber is independent, and sealed with epoxy resin at both ends of the membrane groups. Millions of fiber bundles together provide the required surface area.

Under pressure, all kinds of gas get different rates of absorption, diffusion and infiltration in the hollow fiber membrane. According to penetration order, we call the high infiltration rate gas as "quick gas", such as oxygen, water vapor; low infiltration rate as a "slow air", such as nitrogen. When gas mixture get through the membrane, the "quick gas" has been enriched at low pressure outside; "slow air" has been enriched at high pressure inside, in order to achieve separation of mixed gases.

Membrane nitrogen generator feature
 • Different kinds of module specifications, can economically meet the different needs of users’ requires for the nitrogen
 • High-pressure membrane module, low nitrogen exports pressure loss, can meet the requirements of users’ the needs of high stress
 • By increasing the number of membrane modules can easily expand system capacity of Nitrogen gas.
 • No moving parts, static operation, without special care, very little maintenance, safe, reliable and continuous working.
 • Light weight, compact structure, save space, without infrastructure investment, easy to install and start, open, parking facilitate rapid, automatic operation.
 • Membrane group can be separated oxygen and moisture at the same time, and come out the dry nitrogen gas with low dew point.
 • Optional nitrogen flow, remote monitoring systems, etc.
