High-purity PSA Nitrogen Generator take advantage of the unequal-equal pressure process
- Oct 18, 2018 -

The high-purity PSA Nitrogen Generator uses a high-quality carbon molecular sieve as an adsorbent, and uses the principle of pressure swing adsorption to obtain nitrogen directly from compressed air. Since the adsorption capacity of carbon molecular sieve for oxygen varies significantly with pressure, the pressure of the carbon molecule can be desorbed by desorbing the oxygen molecules adsorbed by the carbon molecular sieve, so that the carbon molecular sieve can be regenerated, and the high-quality nitrogen can be continuously produced.


The high-purity PSA Nitrogen Generator uses a unequal potential equalization process, while the conventional nitrogen generator uses an equipotential pressure equalization process. There are two benefits to pressure equalization. One is to reduce the impact of gas on the molecular sieve, and the other is to increase the utilization of compressed air. The inequality couples' pressure process is more reasonable, scientific and mature. The direct effect is that the nitrogen recovery rate is increased, the gas production is increased, and the indirect effect is to reduce energy consumption by 30%.


In addition to the unequal equalization process, the high-purity PSA Nitrogen Generator is equipped with a suitable air compressor so that under the action of the catalyst, nitrogen reacts with a small amount of hydrogen source in the system to remove residual oxygen. After that, excess hydrogen is removed, and a purified filter in a purified adsorption dryer removes impurities, water and dust from nitrogen to obtain high-purity nitrogen.
