For the same adsorbed gas (adsorbate) in any adsorprtion, the lower temperature, the higher pressure and the larger adsorbing capacity when absorption remains stable; otherwise, the higher temperature, the lower pressure and the smaller adsorbing capacity. If the temperature remains unchanged, desorption with decompression (vacuum pumping) or under normal pressure is called pressure swing adsorption (PSA) in the event of adsorption under compression.

As shown above, the size of adsorption of oxygen and nitrogen by carbon molecular sieve varies largely. Nitrogen and oxygen can be separated due to the size difference of oxygen and nitrogen adsorption from the air under some pressure. When the pressure rises, carbon molecular sieve adsorbs oxygen and generates nitrogen; when the pressure falls to normal, the sieve desorbs oxygen and regenerates nitrogen. Usually, the PSA nitrogen generator has two adsorbers, one of which adsorbs oxygen and produces nitrogen, and the other desorbs oxygen and regenerates nitrogen. In this way, nitrogen is produced continuously.




1. The equipment employs non-unipotential pressure-equalizing processes until consumption of compressed air is reduced directly.

2. Ae can select the most energy-saving molecular sieve according to customers' conditions.

3. Advanced load adaptive technology to further reduce energy consumption.

4. Advanced packing technology to make carbon molecular sieve more compact and uniform and minimize friction coefficient.

5. Most reliable gas supply treatment to ensure adsorption efficiency and service life of the sieve.

6. Switchover valves and components of famous brands employed to ensure product quality.

7. Advanced automatic cylinder compaction technology.

8. The equipment can be monitored on a real-time.

9. Ineligible nitrogen can be emptied automatically.

10. Friendly HMI.

1. Leave the entire equipment standing in place simply.

2. Leave the entire equipment unmanned when it works because it employs Siemens PLC, equipped with fault alarm.

3. There is a standard R232 port in the control box of intelligent nitrogen generator. So the nitrogen generator can be remote- monitored when it is connected to the User's DCS.





Nitrogen and oxygen from the air can be separated with carbon molecular sieve by compressed adsorption and decompressed desorption.




The German nitrogen generating process and molecular sieve filling technology are employed to maximize the adsorption efficiency and stacking density of molecular sieve.

The drum-separated adsorption structure causes the sieve bed to work permanently still without a hold-down gear, which ensures the sieve is free of mechanical wear. The imported core components ensure gas purity and flow keep stable long.
