Description of PSA Nitrogen Generating plant features:

1. The PSA advanced process is a simple nitrogen production method, which produces nitrogen a few minutes after power-on, with low energy consumption and nitrogen cost lower than that of cryogenic air separation.

2.Reliable and safe performance: microcomputer control, automatic operation, no special training operators, just press the start switch, can automatically run, to achieve continuous production of nitrogen.

3.Nitrogen purity stable, fully monitored by the instrument 'display, ensure the purity of nitrogen required.

4.The selection of high-quality Carbon Molecular Sieve: With a large adsorption capacity, high compressive performance, long service life.

5. High Quality Control Valve: High Quality Pneumatic Valve with special pipe can ensure stable and reliable operation of PSA nitrogen generating plant.

6.Strong Technical Force and excellent after-sales service:Equipment containerization, field installation, only connection,gas, power; excellent electrical and Mechanical Assembly technology, to provide continuous technical services, in charge of field commissioning and training operations.

Work principle

The PSA process is used to separate the gas. The principle of the PSA process is that the impurities in the raw material can be removed by high pressure adsorption under the condition of selective adsorption of adsorbent, these impurities are removed at low pressure and the ADSORBENT is regenerated. The whole operation is carried out at ambient temperature. Under the condition of adsorption equilibrium, when any adsorbent adsorbs the same gas, the higher the gas pressure is, the bigger the adsorption quantity is. On the contrary, the lower the pressure, the smaller the adsorption capacity.

When the air pressure rises, the carbon molecular sieve will absorb a lot of oxygen, carbon dioxide and water. When the pressure drops to normal pressure, the adsorption of oxygen, Carbon Dioxide and water on carbon molecular sieve is very small. Pressure Swing adsorption equipment is mainly composed of a, B adsorption tower with carbon molecular sieve and control system. As the Compressed air (pressure generally 0.65 MPA) passes through tower a from bottom to top, oxygen, carbon dioxide, and water are absorbed by the carbon molecular sieve, while nitrogen passes through and flows from the top of the tower. When the molecular sieve in tower a is saturated, the adsorption process is switched to tower B and the molecular sieve in tower a is regenerated simultaneously. The so-called regeneration is the process of releasing oxygen, Carbon Dioxide and water adsorbed by molecular sieve, which is convenient for the next cycle of adsorption.
