On-site PSA Nitrogen Filling Station

How does PSA nitrogen generator work?

Dry compressed air is blown through a valve to the first vessel where the pressure is built, the O2 is adsorbed by the CMS(carbon molecular sieves)pellets during the building of pressure, and the N2 will pass through to the accumulation tank. Due to the property of the O2, it moves faster than N2 in the carbon molecular sieve, so the oxygen molecular has been adsorbed first and the N2 has been collected and finally get the N2 air. After then the carbon molecular sieve would be decompressed to release the O2 molecular. The two vessels , one is for working the other is regeneration. They are all controlled the PLC and valves, so it can keep running without stopping.

While pressure is building up in one vessel, the other vessel is regenerating through decompressing, this process guarantees a continuous flow. Before the subsequent adsorption or desorption stage, the pressure between the adsorption vessels will be equalised. When the pressure decreases in the first vessel, and the ZMS or CMS pellets are saturated, the waste product is exhausted through the exhaust system. the pressure in the second vessel will now build up until the pressure between both vessels is once again equalised.
