Working Principle

Ultra-low air consumption PSA nitrogen production is an advanced gas separation technology that uses high-quality carbon molecular sieve (CMS) as an adsorbent, using pressure swing adsorption at room temperature to separate air and produce high-purity nitrogen.

Selective Adsorption Mechanism

Oxygen molecules (O2) diffuse faster and enter the micropores of carbon molecular sieves more readily than nitrogen molecules (N2). This selective adsorption results in oxygen enrichment in the adsorption phase and nitrogen enrichment in the gas phase, achieving effective separation.

Compressed Air Requirements

Pressure: > 0.7MPa, ≤ 0.8MPa
Residual oil content: < 0.001ppm
Mechanical impurities: ≤ 0.1µm
Pressure dew point: ≤ 8°C
