Principle of Membrane-separating nitrogen generation

 

Membrane-separating nitrogen separation means that nitrogen and oxygen in the air can be separated due to the difference of their permeation rate when their molecules pass through hollow fiber membrane.

 

Example for membrane form

 

Membrane module is mainly in the form of flat plate, roll and hollow fiber.

Now, high polymer membrane in the form of hollow fiber is most prospective in application. Major material and structure of gas separating membrane

Performance of gas separating membrane -1

Gas output: Flow of gas available in a unit time; increased with pressure and temperature rising

Recovery: Percentage of gas flow available in a unit time to mixed gas flow Service life: The service life of membrane is related to membrane performance, working environment and maintenance.


Note: High recovery means small consumption of compressed air, which increases slightly with pressure rising and decreases slightly with temperature rising.
