Nitrogen Generator

PSA nitrogen generator is based on the principle of pressure swing adsorption, using a high-quality carbon molecular sieve as the adsorbent. Under certain pressure, due to the dynamic effect, the diffusion rate of oxygen and nitrogen on the carbon molecular sieve is quite different.

The oxygen molecules are largely adsorbed by the carbon molecular sieve, and the nitrogen molecules are enriched in the gas phase to achieve the separation of oxygen and nitrogen. Since the oxygen adsorption capacity of the carbon molecular sieve varies significantly with pressure, reducing the pressure can desorb the oxygen molecules adsorbed by the carbon molecular sieve, so that the carbon molecular sieve can be regenerated and reused.

Two adsorption tower processes are adopted, one is for adsorption and nitrogen production, and the other is for desorption and regeneration, alternating cycles, and continuous production of high-quality nitrogen.

Technical characteristics

• With pressure swing adsorption as the process principle, it is mature and reliable.
• Perfect process design, optimal use effect.
• Intelligent soft cycle switching, purity, and flow rate can be adjusted within a certain range.
• Unique molecular sieve protection measures extend the service life of carbon molecular sieve.
• The relevant system components are reasonably configured and the failure rate is low.
• Reasonable internal components, uniform airflow distribution, reducing the impact of high-speed airflow.
