Our technical team was invited to our clients PSA Nitrogen Generator project site to guide the Carbon Molecular Sieve installation on 14th,Jan 2022.
Filling the new carbon molecular sieve to the columns:
You might want to know more details about what carbon molecular sieve is and what industry it is widely used? Let’s get this straight now!
Description of Carbon Molecular Sieve:
Atmospheric air contains 78 % of nitrogen & 21% of oxygen. Nitrogen in PSA (Pressure Swing Adsorption) method is generated by physical separation of oxygen from atmospheric air and outlet the Nitrogen, using XINTAO adsorbent Carbon Molecular Sieve which which preferentially adsorb oxygen molecules, CO and CO2 whereas nitrogen molecules is not adsorbed by CMS due to its larger molecular size.
The compressed air is passed through PSA 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 carbon molecular sieves (CMS).
At a time one tower remains under nitrogen 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 + 1 minute. The outgoing nitrogen gas is sent to a surge vessel where the minimum nitrogen pressure will be maintained with the help of Back pressure Regulator. The product nitrogen will now be sent to the consumer point through a pressure reducing valves at required pressure.
