Liquid oxygen Nitrogen Air separation Unit Air separation plant
1. Air Compressor: Air is compressed at a low pressure of 5-7 bar (0.5-0.7mpa)
2. Pre Cooling System: Cooling the temperature of air to around 12 deg C.
3. Purification of Air By Purifier: Twin molecular Sieve driers
4. Cryogenic Cooling of Air by Expander: Turbo expander cools the temperature of air below -165 to-170 deg C.
5. Separation of Liquid Air into Oxygen and Nitrogen by Air Separation Column
6. Liquid Oxygen/Nitrogen is stored in a Liquid Storage Tank

Technology
1.Air Separation Unit with normal temperature molecular sieves purification, booster-turbo expander, low-pressure rectification column, and argon extraction system according to client's requirement.
2.According to the product requirement, external compression,internal compression (air boost,nitrogen boost),self- pressurization and other processes can be offered.
3.Blocking structure design of ASU, quick installation on site.
4.Extra low pressure process of ASU which reduce air compressor exhaust pressure and operation cost.
5.Advanced argon extraction process and higher argon extraction rate.

PSA OXYGEN GENERATOR PSA oxygen generator plant is fabricated using advanced Pressure Swing Adsorption technology. As is well-known, oxygen constitutes around 20-21% of atmospheric air. PSA oxygen generator used Zeolite molecular sieves to separate the oxygen from the air. Oxygen with high purity is delivered whereas the nitrogen absorbed by the molecular sieves is directed back into the air through the exhaust pipe.

PSA NITROGEN GENERATOR PSA nitrogen generation adopts carbon molecular sieve as adsorbent whose capacity of adsorbing oxygen is larger than adsorbing nitrogen. The two adsorbers (a&b) alternately adsorbing and regenerating to separate oxygen from nitrogen in air to obtain purified nitrogen by Auto-operated valves controlled by PLC |
