Product Description



Nitrogen gas separating membrane

Principle of Membrane-separating nitrogen generation

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

Membrane material and features: 

 type: Using the most advanced polyimide (PI) hollow fiber made

 Materials: aromatic polyimide

 Maximum operating temperature: ~60℃Air separation and drying

                               ~150℃ H2,CO2/dehydration 



(1) High separation coefficient, high product air volume, high recovery rate  

(2) The purity of nitrogen can be adjusted, up to 99.9%

(3) Durability is excellent

(4) High pressure strength: 0.3-2.4MPa

(5) dew point can reach -60 ℃, oxygen-enriched air concentration up to 45%

(6) High reliability, long service life, can reach up to 8 years of film separator's conventional pollutant tolerance

Water/humidity: avoid liquid water entering, humidity < 80RH%

 Granule: controlled below 0.01 mu m

 Residual oil:<0.01mg / Nm3

 Hydrogen Sulfide:<3 vol%

 Ammonia and amines:<100 vppm

 Methanol: 5% (gaseous)

 Acid: to be avoided Aromatic: As much as possible to reduce the content

 Ethanol: May exist

 Methyl ether:<5 vol%

 Benzene:<1 vol%

 Toluene:<2000 vppm

 C5+ hydrocarbons: reaching saturation (avoid liquid)


Application field:

1. Oilfield nitrogen production

2. The coal mine underground mobile fire protection system

3. Chemical, liquid cargo ship (LNG,LPG) ship inert gas protection, ocean platform

4. Storage and air conditioning, fruit and vegetable preservation

5. Chemical pipeline purge, inert gas protection 

6. Food packaging

Our products and cooperation are flexible,from the membrane group, membrane unit, membrane group Design: to membrane nitrogen application technology and service:,we provide the best products and services that meet the customers' requirements!
