PSA nitrogen generator is an efficient and reliable nitrogen production equipment that uses pressure swing adsorption (PSA) technology. It uses air as raw material and separates oxygen and nitrogen in the air through adsorbents at room temperature to produce high-purity nitrogen.

PSA nitrogen production device because of low energy consumption, simple operation, in chemical industry, metal processing, electronics industry, food and beverage, pharmaceutical industry and other fields have been widely used.

Pressure swing adsorption nitrogen production is based on clean, dry compressed air as raw material, and uses a high-efficiency and highly selective solid adsorbent (carbon molecular sieve) to selectively adsorb nitrogen and oxygen to reduce the nitrogen and oxygen in the air. separate from. Carbon molecular sieves are non-polar molecules and preferentially adsorb oxygen. The separation effect of carbon molecular sieve on oxygen and nitrogen is mainly based on the different diffusion rates of these two gases on the surface of carbon molecular sieve. Gas with a smaller diameter (oxygen) diffuses faster, and more enters the solid phase of the molecular sieve. Gas with a larger diameter (Nitrogen) diffuses slowly and less enters the solid phase of molecular sieve. In this way, nitrogen-rich components can be obtained in the gas phase. After a period of time, the adsorption of oxygen by molecular sieve reaches equilibrium. According to the different characteristics of carbon molecular sieve for adsorbing gas under different pressures, the pressure is reduced to release carbon molecular sieve from adsorbing oxygen. This process is called regeneration. The pressure swing adsorption method usually uses two towers in parallel, alternately performing pressure adsorption and decompression regeneration, so as to obtain a continuous nitrogen stream.

As an important energy gas in industrial production, nitrogen is widely used in chemical, metal processing, electronics, food and beverage, pharmaceutical and other industries.
