Principle of pressure swing adsorption (PSA) for nitrogen production

The carbon molecular sieves can simultaneously adsorb oxygen and nitrogen in the air, and the amount of adsorption increases with the increase of pressure, and there is no obvious difference in the equilibrium adsorption between oxygen and nitrogen under the same pressure.

Therefore, it is difficult to complete the effective separation of oxygen and nitrogen by the change of pressure. If the adsorption velocity is further considered, the adsorption characteristics of oxygen and nitrogen can be effectively separated.

The diameter ratio of nitrogen oxygen molecules is small, so that the diffusion speed hundreds of times faster than nitrogen, so the carbon molecular sieve adsorption oxygen adsorption rate is also very fast, about 1 minutes to reach more than 90%; and only 5% of the nitrogen adsorption capacity, so the general adsorption are oxygen, and the rest of the body. Is nitrogen.

So, if the adsorption time control in less than 1 minutes, it can be preliminarily separated oxygen and nitrogen, that is to say, the adsorption and desorption by differential pressure to achieve, adsorption pressure increased, desorption pressure drop.

However, the difference between oxygen and nitrogen is the difference between the adsorption rate and the adsorption time. The time control is very short, and the oxygen has been fully absorbed, and the adsorption process is stopped before the nitrogen has enough time to adsorb. Therefore, pressure swing adsorption to nitrogen pressure changes, but also to control the time within 1 minutes.

1.Nitrogen production is convenient and quick:
Advanced technology, unique air distributor, so that the distribution of airflow more evenly, efficient use of carbon molecular sieve, 20 minutes or so to provide qualified nitrogen.
2.Easy to use:
The utility model has the advantages of compact structure, integral skid, small occupation area, no capital construction investment and little investment, and the nitrogen can be obtained only by connecting the power supply on the spot.
3.More economical:
PSA process is a simple method of nitrogen production. With air as the raw material, the energy consumption is only the energy consumed by the air compressor. It has the advantages of low operating cost, low energy consumption and high efficiency.
4.Mechanical and electrical integration design to achieve automatic operation:
Imported PLC control, fully automatic operation, nitrogen flow, pressure, purity, adjustable and continuous display, can be unattended.
