Techniques

The basic principles of pressure swing adsorption using sorbents have different adsorption capacity of adsorbate at different pressures, and the characteristics of different adsorption to the each component of gas mixtures at a certain pressure. To remove adsorbed impurities of the pressurized feed gas under the adsorption choosing conditions.

Pressure swing adsorption technology, PSA for short, is an advanced gas separation technology based on the physical adsorption to the gas molecules by the internal surface of adsorbent, utilizing the adsorbents easy to absorb high boiling point gases and not easy to absorb low boiling point gas the under the same pressure, and the increasing of absorption under high-pressure, and reducing of adsorption under low pressure to achieve gas separation. Such regeneration process that impurities absorption under pressure and impurities desorption under vacuum is so called pressure swing adsorption cycle.

As the picture showed, under the adsorption balance situation, the higher the pressure is, the more adsorption of CMS will be, and vice verse. Meanwhile, the adsorption of CMS to oxygen gas is much more than the nitrogen gas.

PSA nitrogen generation also called CMS nitrogen generation, just using this principle, using the air as basic material, the CMS as sorbents, and the feature of different adsorption to oxygen and nitrogen to realize the separation of those two gases to produce nitrogen gas.

PSA nitrogen generator is capable of easy technical process, high automatic, fast gas gathering, low energy cost, and high gas purity. The gas purity can be adjusted within a wide range. Easy to maintain and repair, low cost and high device adapted. The small and medium-sized consumers below 3000Nm3 / h get a wide range of applications of nitrogen, and PSA nitrogen has become the preferred method of small and medium-sized users of nitrogen.
