On-Site Nitrogen Generator

The On-Site Nitrogen Generator is attractive, economical equipment to generate nitrogen on-site, ie, near the use points by separating out the oxygen using Pressure Swing Adsorption (PSA) process. Dry and oil-free compressed air at 7 to 8 bar is required as feed air (such a system can be supplied, if required). The PSA system uses a special adsorbent (CMS), which retains the oxygen and allows nitrogen to go through. It has two towers in which one produces nitrogen white the other is regenerated by de-pressurisation. The nitrogen is collected in a surge vessel, which is requited for pressure balancing, as well as purity stabilisation. The pure nitrogen is drawn from the surge vessel at the required flow rate. It can also be accumulated in a storage vessel in case the nitrogen usage in intermittent or if the demand is uneven. The PSA nitrogen generator produces nitrogen similar to that of a commercial nitrogen cylinder, minus the hassles and hazards.
