Nitrogen Generator

Lixin is a professional manufacturer of PSA Nitrogen Generators, with over 13 years of experience in designing and producing nitrogen pressure swing adsorption (PSA) systems. We offer a wide range of standard models, ensuring that we have a solution to meet your needs.

What is a PSA Nitrogen Generator?

Pressure Swing Adsorption (PSA) is a technology used to separate specific gases from a mixture under pressure, based on the molecular characteristics of the gases and their affinity for the adsorbent material. Unlike cryogenic distillation, PSA operates at near-ambient temperatures. It uses specialized adsorbent materials, such as activated carbon or molecular sieves, which selectively adsorb the target gas at high pressure. The process then switches to low pressure to release or desorb the captured gas.

How Do PSA Nitrogen Generators Work?

The PSA process leverages the principle that gases are attracted to solid surfaces under high pressure, a phenomenon known as adsorption. The higher the pressure, the more gas is adsorbed; when the pressure decreases, the adsorbed gas is released, or desorbed. This process can effectively separate gases from a mixture because different gases have varying levels of attraction to different solid surfaces.

For example, when a pressurized gas mixture (such as air) is passed through a vessel containing a bed of carbon molecular sieve (CMS) adsorbent, which has a higher affinity for oxygen than nitrogen, the oxygen will be retained in the bed while the nitrogen-rich gas exits the vessel. Once the adsorbent bed reaches its capacity to hold oxygen, it is regenerated by reducing the pressure, allowing the oxygen to be desorbed. The cycle then repeats, enabling the continuous production of high-purity nitrogen.

By using two adsorbent vessels, near-continuous production of nitrogen is possible. This setup also allows for pressure equalization, where gas from the depressurizing vessel is used to partially pressurize the second vessel, resulting in significant energy savings—a standard practice in industrial applications.
