What are Nitrogen Generators?
Nitrogen generators are sophisticated machines made to produce nitrogen gas right where it’s needed. This means businesses can skip the traditional ways of getting nitrogen, like using tanks or liquid nitrogen, which often come with high costs and management challenges. These systems are great at capturing nitrogen from the air around us, which contains approximately 78% nitrogen.
The key to these generators is a process known as Pressure Swing Adsorption (PSA). PSA works by taking advantage of how gases behave under different pressures to separate them. To start, air is compressed, treated and then sent into one of the two absorber vessels that are filled with Carbon Molecular Sieves (CMS). The CMS is a special material designed to take in gases we don’t want, such as oxygen, and carbon dioxide, while letting nitrogen flow through. With increasing pressure, the CMS traps these other gases in the compressed air, which lets us collect pure nitrogen.
Once the CMS is saturated, the vessel's pressure is decreased, which lets the captured gases escape back into the air, readying the CMS for the next cycle. At the same time, the system increases pressure in the second vessel, thus maintaining a continuous nitrogen output. This alternating between the two vessels makes sure that there is a steady availability of nitrogen.
