The core of membrane separation is the physical process of gas separation based on the different diffusivity of different components in the air in the membrane fiber wall (polymer material).

Xinran of PSA nitrogen production is carbon molecular sieve, which is a porous carbon based material. In the process of PSA (about 1 minute), it is easier to cause damage to molecular sieve due to pressure and decompression.

Crude nitrogen obtained by pressure swing adsorption (PSA) or membrane system is mixed with a small amount of hydrogen, in reactor filled with metal palladium deoxidizing catalyst residual oxygen react with hydrogen to form water vapor...
