N2 Membrane Type Nitrogen Generator / Air Nitrogen Production Plant

N2 Membrane Type Nitrogen Generator / Air Nitrogen Production Plant

Membrane Type Nitrogen Generator Working Principle 

Under a certain pressure, using the large difference of the diffusion rate between nitrogen and oxygen from the air

in the carbon molecular sieve, a large number of oxygen is adsorpted by carbon molecular sieve, while nitrogen is

collected in a short time, to achieve separation of oxygen and nitrogen.

The adsorption capacity of carbon molecular sieve is significantly different with different oxygen

pressures, reducing the pressure will release oxygen from carbon molecular sieve, this make carbon molecular

sieve regeneration, then can be used repeatedly.

Using two adsorption towers, one for adsorption and nitrogen generator, the other for desorption and recycling.

They switch with each other, thus continuous output of high-quality nitrogen.

Nitrogen separation

At the heart of the Nitrogen Membrane separation technology are polymeric membrane materials that 

allow for the rapid passage of one gas while minimizing the passage of another when applying pressure 

gradient across the membrane. Membrane materials are formed into hollow fibers to provide high 

surface area for high bolometric gas processing rates.

Selective Permeability

Nitrogen membranes separate gases by the principle of selective permeation across the membranes 

wall. 

For nitrogen polymeric membranes, the rate of permeation of each gas is determined by its solubility 

in the nitrogen membrane material, and the rate of diffusion through the molecular free volume in the 

nitrogen membrane wall. Gases that exhibit high solubility in the nitrogen membranes, and gases that 

are small in molecular size, permeate faster than larger, less soluble gases.

Fast Gases and Slow Gases

"Fast" gases permeate through the nitrogen membrane wall more readily than "slow" gases, thus 

separating the original gas mixture into two streams. The purity of the desired streams can be adjusted 

by changing the operating conditions. 

The ability of a nitrogen membranes to separate two gases is determined by their "selectivity", the ratio 

of permeabilities of the two gases. The higher the selectivity, the more efficient the separation and less 

energy is needed to run the system.
