Modularisation Technology PSA Nitrogen Generator, Nitrogen Generation System
Process Description
A supercharger is used to increase air pressure. Then, a freeze dryer was introduced to remove moisture. Finally, a carbon molecular sieve bed is used to separate the nitrogen from the oxygen, thus ensuring the ideal nitrogen product.
The adsorbent is carbon molecular sieve. It is the use of the different adsorption rates of oxygen and nitrogen on the surface of the carbon adsorbent to adsorb O2 and desorb N2. On-off valves are controlled by a Programmable Logic Controller (PLC) to complete each cycle of adsorption and desorption, which then produces nitrogen at the required purity. The two adsorbers alternate adsorption and desorption to ensure a constant and steady generation of nitrogen.
