Summary: Pressure swing adsorption (PSA) air separation equipment uses high-quality carbon molecular sieves as adsorbents and utilizes the principle of pressure swing adsorption to directly obtain nitrogen from compressed air. Due to the significantly different adsorption capacities of carbon molecular sieves for oxygen under different pressures, the adsorbed oxygen molecules can be desorbed by reducing the pressure, allowing the carbon molecular sieve to be regenerated, repeatedly cycled, and alternately used to continuously produce high-quality nitrogen.

  Pressure Swing Adsorption Air Separation EquipmentTechnical characteristics.

  1. Perfect and smooth design, better use effect;

  2. Reasonable internal components, uniform airflow distribution, reducing high-speed airflow impact;

  3. Special molecular sieve protection measures to extend the service life of the carbon molecular sieve;

  4. Simple operation, stable operation, high degree of automation, unmanned operation;

  5. Automatic interlock nitrogen discharge device to ensure the quality of product nitrogen;

  6. Optional nitrogen device flow rate, purity automatic adjustment system, remote monitoring system, etc.

  Technical advantages of pressure swing adsorption air separation equipment:

  1. Unequal voltage sharing.

  Pressure swing adsorption air separation equipment adopts unequal potential pressure equalization technology, while traditional nitrogen generators adopt equal potential pressure equalization technology. Pressure equalization has two advantages: one is to reduce the impact of gas on the molecular sieve, and the other is to improve the utilization rate of compressed air. The unequal pressure process is more reasonable, scientific, and mature. Its direct effect is to improve nitrogen recovery rate and gas production rate, and the indirect effect is to reduce energy consumption by 30%. 2. Easy installation.2. Easy installation.

  This pressure swing adsorption air separation equipment has a compact structure, overall skid mounting, small footprint, requires no capital investment, and low investment.

  3. Excellent carbon molecular sieve.

  Pressure swing adsorption air separation equipment has the advantages of large adsorption capacity, strong pressure resistance, and long service life. Normal operation and service life can reach10 years.

     Pressure Swing Adsorption Air Separation EquipmentPLC control fully automatic operation. The purity of nitrogen flow and pressure can be continuously adjusted and displayed. Pressure, flow rate, and purity can be set to start emergency signals, realizing remote automatic control, inspection, and measurement, achieving true unmanned operation. The advanced control system makes operation simpler, enabling unattended and remote control, and real-time monitoring of various operating conditions, thus ensuring the stability of gas purity and flow rate.
