Nitrogen Generation Module PSA Nitrogen Plant 20Nm³/hr
A Pressure Swing Adsorption nitrogen generator (PSA nitrogen generator) is advanced gas separation equipment that extracts high-purity nitrogen from ambient air using the Pressure Swing Adsorption principle. By utilizing the selective adsorption capacity of carbon molecular sieve (CMS) for oxygen and nitrogen, it achieves efficient separation without chemical reactions, ensuring stable and continuous nitrogen supply. Key advantages include onsite nitrogen generation, eliminating costly nitrogen cylinder transportation and storage, along with remarkable energy-saving performance compared to traditional methods. With flexible modular design and easy scalability, modular nitrogen generator variants adapt to diverse industrial demands, while high automation reduces manual intervention and operational costs.

Working Principle of PSA Nitrogen Generation System
The PSA nitrogen generation system operates through a cyclic process of adsorption and desorption, leveraging the different adsorption capacities of carbon molecular sieve for oxygen and nitrogen. When compressed air (filtered to remove oil, water, and impurities) enters the adsorption tower under pressure, oxygen molecules are preferentially adsorbed by the CMS, while nitrogen molecules pass through and are collected as product gas. When one tower reaches adsorption saturation, the system switches to the other tower for continuous production, while the saturated tower undergoes depressurization and regeneration to release adsorbed oxygen. This fully automated cyclic process ensures 24/7 stable supply of high-purity nitrogen, and the PSA technology for nitrogen generation is widely recognized for its high efficiency and reliability in industrial applications.
