High Purity Mobile Nitrogen Gas Generator Carbon Steel PSA N2 Generator

High Purity Mobile Nitrogen Gas Generator Carbon Steel PSA N2 Generator

The Nitrogen Generator uses two twowers of CMS to separate nitrogen from the compressed air, remove other gas like oxygen, CO2 etc , Typical feed air pressure is 110 psig/7.6 barg. Typical nitrogen product purity for SINCE GAS systems is 99.998%. Product flow rate for the same system will be higher with better nitrogen recovery if a higher oxygen content can be accepted in the nitrogen product. Systems are available with a product purity up to 99.999% nitrogen. Presently, our nitrogen generator purity range from 95%-99.9995%, flow 5Nm3/hr -5000 Nm3/hr

PSA Nitrogen Generator System is used worldwide.

Principle of Operation

PSA Nitrogen Gas Generator produces N2 gas, using air as raw materials and carbon molecular sieve as adsorbent, by the selective adsorption of carbon molecular sieve to O2 and N2, achieving the separation of the N2 and O2 in the air.

PSA( Pressure Swing Adsorption) is an advanced gas separation technology, based on the physical adsorption of the internal surface in the adsorbent to gas molecules, separating the gas by the characteristics of absorbing to the quantity of different gas in general pressure. The CMS (Carbon Molecular Sieve) is a sorbent picked up from the air, used in separating Oxygen and Nitrogen molecular. The absorption quantity of CMS is greatly higher for Oxygen than Nitrogen under the same pressure.

Process Flow Brief Description

Composition of PSA nitrogen making machine

Compressed air purification system:Carbon molecular sieve is the key material to determine the production capacity of nitrogen machine. Since the compressed air provided by air compressor usually contains oil and water, oil and water will reduce the adsorption capacity of carbon molecular sieve, so the compressed air needs to remove oil and water before entering the oxygen and nitrogen separation system. Firstly, the air is compressed by the compressor to be 0.75-1.0 MPa and enter air purification system, the pipeline filter will remove most of the water, oil and mechanical impurities, and then the freeze drying machine dewaters by cooling and make the pressure dew point to be 2 ℃ to 10 ℃, furthermore, the air is processed by the precision filter, super precision filter and activated carbon degreaser, the air with pressure 0.75-1.0 MPa, pressure dew point with 2 ℃ to 10 ℃, and the oil content less clean 0.01 PPm will be got. Compressed air purification system is composed of pipeline filter, freeze-drying machine, fine filter, ultra-fine filter, activated carbon deoiler, automatic sewage valve, ball valve and so on.
