working principle

 

Membrane separation Nitrogen technology is based on the nitrogen and oxygen in the air pressure on both sides of the membrane under the effect of the membrane in the solubility and diffusion coefficient to achieve different separation, the permeability of water vapor, oxygen and some gas first through Film, become oxygen-rich gas, while slower permeability of nitrogen is retained enrichment, a dry nitrogen-rich gas to achieve the purpose of oxygen and nitrogen separation

 

Technical characteristics

Simple operation, reliable operation, high degree of automation, no moving parts, no cycle switching, to meet the long-term continuous operation requirements;

Open / stop quickly, about 10 minutes boot to produce qualified nitrogen;

Low energy consumption, continuous adjustment of nitrogen purity;

Gas separation process no noise, no pollution, no harmful waste, high nitrogen cleanliness;

By adding membrane modules to expand the system capacity of nitrogen production to meet customer needs for different nitrogen production;

With the film group of gas quality testing and protection devices to ensure that qualified gas into the membrane module to improve the life of the membrane;

Machine compact structure, easy installation, small footprint;

Wide range of applications, can resist many chemical pollution;

Optional remote monitoring system, automatic purity control device, DSC communications.

Can be divided into fixed, mobile, car and other models.

Can be divided into low pressure, medium pressure, high pressure series.

Technical indicators

 

Nitrogen production: 5 ~ 3000Nm / h

Purity of nitrogen: 95% ~ 99.9%

Nitrogen pressure: 0.1 ~ 2.0Mpa (adjustable, pressurized)

Nitrogen dew point: -40 ℃ ~ -60 ℃

When different gases pass through the hollow fiber membrane, they are separated according to the permeation rate
