    PSA Nitrogen Generator


    Here's some additional information about nitrogen generators and their principles of operation:

    Pressure Swing Adsorption (PSA): PSA nitrogen generators use a molecular sieve adsorbent material, typically carbon molecular sieves (CMS), to selectively adsorb oxygen and other impurities while allowing nitrogen to pass through. The adsorbent material is contained in columns or beds, and the compressed air is directed through these beds in a cyclic process. By adjusting the pressure, two columns can alternate between adsorption and regeneration stages, ensuring a continuous supply of nitrogen.

    Membrane Separation: Membrane nitrogen generators utilize specialized polymer membranes that have selective permeability to gases. These membranes have tiny pores or channels that allow smaller molecules like nitrogen to pass through while larger molecules such as oxygen and other impurities are retained. The compressed air is passed through these membranes, separating the nitrogen from the rest of the gases.

    PSA vs. Membrane: PSA nitrogen generators are typically used for higher purity applications, where nitrogen purities of up to 99.999% (5.0 grade) are required. Membrane nitrogen generators are suitable for lower purity applications, typically ranging from 90% to 99.9% purity (1.0 to 3.0 grades). The choice between PSA and membrane systems depends on the specific requirements of the application, such as desired purity, flow rate, and cost considerations.

    Flow and Purity Control: Nitrogen generators are equipped with control systems that allow adjustment of the nitrogen flow rate and purity levels. The flow rate can be controlled by regulating the input air pressure, while the purity is monitored and controlled by adjusting the cycling time, adsorbent material properties, or membrane configuration.

    Applications: Nitrogen generators find extensive use in various industries, including food and beverage packaging, electronics manufacturing, pharmaceuticals, chemical processing, metal fabrication, and oil and gas. They are used for processes such as inerting, blanketing, purging, flushing, and sparging, where a controlled nitrogen atmosphere is essential to protect products, prevent oxidation, maintain product quality, and improve safety.

    Overall, nitrogen generators provide a cost-effective and reliable solution for on-site nitrogen production, eliminating the need for traditional nitrogen cylinders or liquid nitrogen supply. They offer flexibility, efficiency, and the ability to customize nitrogen production based on specific application requirements.

    PSA Nitrogen Generator Technical features :

    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.
    6. Reasonable structure design make the transportation, sling and installation very convenient.
    7. Selecting the safe and reliable control components, so the equipment can run stable and reliable,it also has various fault alarm.
    8.It operates easily, runs stably, and has a high degree of automation, can realize no one operates.
