Nitrogen Generation from PSA - 2
Product Specifications
Product Description
Air, after pressurized to the adsorption pressure by air compressor, is fed into adsorbers prior to passing the filtration of refrigerating dryer. The adsorbent is carbon molecular sieves. It is just making use of the property that adsorption amount of oxygen and nitrogen differs on the surface of the carbon adsorbent to adsorb O2 and desorb N2. The opening and closing of the program valves are controlled by the programmable logic controller (PLC) to complete each cycle of adsorption and desorption and then N2 is produced with the required purity. The two adsortbers are in adsorbing and desorbing alternatively to ensure N2 to be generated constantly and steadily.

Over-trace H2 |
ANCH |
Process of over trace H2 hydrogenation: Adopting high-efficiency deoxidation catalyst, and both hydrogenation and deoxidation in a single adsorber. |
|
Low-trace H2 |
ANCH |
Process of hydrogenation and deoxidation: Two kinds of catalysts in series with low trace H2 process. |
|
ANCH |
Low trace H2 and deoxidation process. Adopting high-efficiency deoxidation agent and adsorbent. |
|
No H2 |
ANCH |
Process of purification directly: No need hydrogenation in the process of gas generation, and the product is low trace H2 or no H2, but a small quantity of H2 is required by the deoxidation machine for replacement. |
