The adsorption gas separation process in nitrogen ...

The adsorption gas separation process in nitrogen generators is based on the phenomenon of fixing various gas mixture components by a solid substance called an adsorbent. This phenomenon is brought about by the gas and adsorbent molecules' interaction. Nitrogen generators are used in hypoxic air fire prevention systems to produce air with a low oxygen content which will suppress a fire. A nitrogen generator not only removes the hassle of having to change over cylinders, it provides an uninterrupted supply of gas at a consistent purity. This consistency is generated using one of two technologies, namely, Pressure Swing Adsorption (PSA) and membrane nitrogen generators. Essentially, a nitrogen generator works by separating nitrogen molecules from the oxygen molecules within compressed air. In addition to allowing companies to control how much nitrogen they want to produce with how much pressure and which degree of purity, generating the gas themselves has other benefits.
