Fully Automatic PSA Nitrogen Generator 5-5000 Nm3/h 95-99.9995% Purity

High Purity, Fully Automatic PSA Nitrogen Generator Multipurpose Application

PSA Nitrogen Generator Principles:

PSA nitrogen generator uses a carbon molecular sieve as sorbent and produces nitrogen by making use of the PSA principle. Under certain pressure, a carbon molecular sieve has different oxygen/nitrogen adsorption capacity, i.e. much more oxygen adsorption capacity than nitrogen adsorption capacity. PLC controls the pneumatic valve on/off to realize two towers alternate adsorption and desorption as per pressure change, carries out oxygen/nitrogen separation, and produces nitrogen with desired purity.
PSA Nitrogen Generator incorporates one air compressor, refrigerant air dryer and filters, main nitrogen generator, air buffer tank, and nitrogen buffer tank. With higher nitrogen pressure required, one BROTIE totally oil-free nitrogen compressor will be equipped after the nitrogen generator to increase the nitrogen pressure to the required pressure.
Compressed air is purified through the air dryer and filters to a certain level for the main generator to work with. Air buffer is incorporated for a smooth supply of compressed air thus reducing the fluctuation of work demand for air compressors. The generator produces nitrogen with PSA (pressure swing adsorption) technology, a time-proven nitrogen generation method. Nitrogen with a desired purity is delivered to a nitrogen buffer tank for a smooth supply of product gas. Nitrogen in the buffer tank is maintained at 6barg pressure. After a totally oil-free nitrogen compressor, the pressure will be compressed to the required pressure. It is adjustable for you to adjust the outlet pressure by a pressure regulator valve, so that it can be used for your specific use.

3. Advanced load adaptation technology further saves energy.

4. The most reliable air cleaning process ensures adsorbing efficiency and the lifetime of CMS.

5. National patent valve guarantees stable equipment operation.

6. Air tank ensures stable system air consumption.

7. Nitrogen buffer tank ensures stable system gas supply.

8. National patent compaction technology ensures the long life of CMS.

9. Long-distance supervision and control.

Air is composed of 78% Nitrogen and 21% Oxygen. PSA Nitrogen generation technology works on the principle of air separation by adsorbing Oxygen and separating Nitrogen.

The pressure Swing Adsorption (PSA Nitrogen) process comprises 2 vessels filled with Carbon Molecular Sieves (CMS). (see image below for detail of vessels).

Step 1: Adsorption
Pre-filtered compressed air is passed through one CMS-filled vessel. The CMS adsorbs oxygen and

Nitrogen comes out as the product gas. After some time of operation, the CMS inside this vessel gets

saturated with Oxygen and can no longer adsorb.
Step 2: Desorption
Upon saturation of the CMS in the vessel, the process switches nitrogen generation to the other vessel,

while allowing the saturated bed to start the process of desorption and regeneration. The waste gas (oxygen, carbon dioxide, etc.) is discharged into the atmosphere.
Step 3: Regeneration
In order to regenerate the CMS in the vessel, part of the Nitrogen produced by the other tower is purged

into this tower. This allows for quick regeneration of the CMS and makes it available for production in the next cycle.

The cyclical nature of the process between the two vessels ensures the continuous production of pure

Nitrogen.
