Low Energy Consumption Membrane Nitrogen Generator For Semiconductor Devices

Membrane Nitrogen Generator Introduction

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.

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.

Membrane Nitrogen Generator Application:

1. Metallurgy: protection gas of metal heat treatment, metal welding, magnetic materials, metal powder sintering.
2. Chemical industry: chemical fiber, pesticides, protection gas of various chemical products, pressure feed, replacement, cleaning, covering, paint stir.
3. Oil, gas: oil-refining, petroleum oil nitrogen injection exploitation, weather containers, pipelines nitrogen sweeping, leak detection, replacement, offshore oil exploitation.
4. Mine: underground explosion prevention, coalfield fire prevention.
5. Medicine: nitrogen filling storage of Chinese herbal medicine, nitrogen filling and oxygen discharging packaging of western medicine and injection, and drug material pneumatic transmission.
6. Electronics: nitrogen protection in the processing of integrated circuits and semiconductor devices, purifying the treasury, drying and clean packaging.
7. Food: nitrogen filling packaging, gas adjustment fresh storage of fruits and vegetables, nitrogen filling and oxygen discharging packaging of liquor and beverages and edible oil stir.

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.
