PSA Nitrogen Plant Working Principle
The PSA nitrogen plant working principle is based on the selective adsorption of oxygen molecules using carbon molecular sieve. Ambient air is compressed and passes through a marine-grade pretreatment system to remove oil, moisture, and particulate contaminants.
The purified air enters adsorption vessels where oxygen is adsorbed under pressure, while nitrogen passes through as product gas. When the adsorbent reaches saturation, the pressure is reduced, releasing the adsorbed oxygen. By alternating between adsorption and regeneration cycles, the system achieves continuous pressure swing adsorption for nitrogen generation.
This proven PSA technology for nitrogen generation forms a highly reliable nitrogen PSA unit, capable of long-term operation in marine environments.
