Liquid Nitrogen Generation Plant

 Process Flow Brief 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.

Technical Features 

1.  It is an advanced technology with less investment.
2.  The quality is reliable and both the N2 purity and quantity are stable.
3.  The unit is supplied in a skid-mounted manner, which can be transported and installed easily.
4.  It is full automatic control and no need for operators, easy to start-up and shutdown, simplified and

convenient maintenance.
