Working Principles for PSA Nitrogen Generator
A Pressure Swing Adsorption (PSA) nitrogen generator is an automated system that utilizes air as its raw material. By employing carbon molecular sieve as the adsorbent, it applies the principle of pressure reduction desorption to selectively adsorb oxygen from the air, resulting in the separation of nitrogen.
Main Features for PSA Nitrogen Generator
- The production of nitrogen involves utilizing ambient air as the raw material, which is readily available in nature. By supplying compressed air and power, nitrogen can be efficiently generated. The purity of nitrogen can be conveniently adjusted according to specific requirements by controlling the input of compressed air.
- The equipment used for nitrogen generation is highly automated, allowing for rapid gas production without the need for continuous monitoring. It can operate unattended and starts producing nitrogen within a short timeframe of 10-15 minutes after startup.
- The equipment itself is designed with simplicity in mind, occupying a small footprint, consuming minimal energy, and offering cost savings. Its streamlined process flow contributes to its compact size and energy efficiency.
- To ensure the durability and long-term use of the molecular sieves, they are filled using the snowstorm method. This technique prevents the pulverization of the molecular sieves caused by the impact of high-pressure airflow, safeguarding their performance and extending their lifespan.
- Regarding the online inspection of imported analyzers, they are characterized by their simplicity, high accessibility, small physical footprint, low energy consumption, and cost-effectiveness.
