Automatic Nitrogen Generation System / Heavy Duty Nitrogen Gas Generator

Automatic Nitrogen Generation System / Heavy Duty Nitrogen Gas Generator

PSA Nitrogen Generator Priciple

PSA technology allows nitrogen molecules to be isolated from other molecules in compressed air (water, oxygen, CO2, etc). The carbon molecular sieve (CMS), the adsorbent in the generator, retains all those molecules and only lets the nitrogen pass through to the outlet. While the CMS in one vessel regenerates a second, connected vessel goes through the same adsorption cycle. These two connected vessels work together to ensure a near- continuous flow of nitrogen gas.

PSA Nitrogen Generator Application:

1. Oil tanker ship
2. Chemical ship
3. LNG ship
4. Oil&Gas project

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.

Pressure Swing Adsorption (PSA Nitrogen) process comprises of 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. Oxygen is adsorbed by the CMS

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 start the process of desorption and regeneration. The waste gas

(oxygen,carbon dioxide, etc.) is discharged into 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 to make it available for production in

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

Nitrogen.

PSA Nitrogen Generator Technical characteristics

1. Unique molecular sieve protective measures so as to lengthen the service life of carbon

molecular sieve.

2. Self reliance type cylinder pressure device can avoid high speed airflow rushed out ,

it can not cause of molecular sieve pulverization phenomenon. equipped with the limit settlement

alarm system,when it reach the floor level of journey,the equipment will sound and light alarm by itself.

3. Configured DCS remote control system interface,it can monitor the system operate condition through

the computer.

4. Intelligent interlocking nitrogen vent device can guarantee the quality of nitrogen.

5. Perfect process design and excellent energy conservation characteristics reduce the cost of gas.
