PSA Nitrogen Generators (Pressure Swing Adsorption) Technology. PSA technology utilizes two towers which are filled with carbon molecular sieve (CMS). Oxygen and other trace gases are preferentially adsorbed by the CMS, allowing nitrogen to pass through.Click to see full answer. Similarly one may ask, how does a PSA nitrogen generator work?Pressure Swing Adsorption (PSA): PSA nitrogen generators utilize Carbon Molecular Sieve (CMS) material to strip oxygen from the source compressed air. As compressed air passes over the material, oxygen molecules are adsorbed into the pores, while the larger nitrogen molecules can pass through to the exhaust gas. what is the purpose for the nitrogen generation system? Nitrogen generators are used in hypoxic air fire prevention systems to produce air with a low oxygen content which will suppress a fire. Also to know, how does a PSA unit work? Pressure swing adsorption (PSA) is a technology used to separate some gas species from a mixture of gases under pressure according to the species’ molecular characteristics and affinity for an adsorbent material. The process then swings to low pressure to desorb the adsorbed material.How do you make nitrogen gas?Nitrogen is produced commercially almost exclusively from air, most commonly by the fractional distillation of liquid air. In this process, air is first cooled to a temperature below that of the boiling points of its major components, a temperature somewhat less than – 328°F (-200°C).
