Working Principle
The PSA nitrogen plant working principle is based on selective adsorption of oxygen and nitrogen molecules. Compressed air is first purified to remove oil, dust, and moisture, ensuring long service life of the carbon molecular sieve. The clean air then enters adsorption towers where oxygen is preferentially adsorbed, while nitrogen flows through as product gas.
Through cyclic pressure changes, the system achieves continuous pressure swing adsorption for nitrogen generation. This mature PSA technology for nitrogen generation guarantees high efficiency, low energy consumption, and consistent nitrogen purity, forming a reliable nitrogen PSA unit for industrial use.
