Atmospheric air contains 78 % of nitrogen & 21% of oxygen. Oxygen in PSA (Pressure Swing Adsorption) Method is generated by Physical separation of Nitrogen from atmospheric air and outlet the Oxygen is collected for use.
The compressed air is passed through PSA Oxygen Tower which is interconnected with automatic changeover valves. In this Process, We can provide separate /Desiccant air Dryer. This has tendency of adsorbing moisture from compressed air. After that Dried compressed air will now come in contact with bed of Zeolite molecular sieves (ZMS). Zeolite Molecular Sieves are special grade of adsorbent which have the property of preferential adsorption of Nitrogen molecules. At a time one tower remains under Oxygen production cycle, whereas the other tower undergoes regeneration which is achieved through depressurization of the tower to atmospheric pressure. The two towers of PSA modules are inter-connected with automatic changeover valves through pneumatic signal given by solenoid valve which in turn get the electrical signal from the timer provided in the control panel. The changeover time cycle will be 1.5 + 1.5 minute. The outgoing Oxygen gas is sent to a surge vessel where the minimum Oxygen pressure will be maintained with the help of Back pressure Regulator. The product Oxygen will now be sent to the consumer point through a pressure reducing valves at required pressure.Why KB Polytech Pvt.Ltd.
