Cryogenic Liquid Nitrogen Plant Air Separation Equipment

                   Cryogenic Liquid Nitrogen Plant Air Separation Equipment
Product Description A air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases.The most common method for air separation is cryogenic distillation. Cryogenic air separation units are built to provide nitrogen or oxygen and often co-produce argon.     Air Separation Plant Performance: 1. Range Oxygen (cu. Mtr/hr): 180 M3/hr ~ 50000 m3/hr 2. Nitrogen Pressure out of Column (bar): 7 bar 3. Oxygen purity GAS 99.7% at 150-160 Bar (2200PSIG) or up to 200/300 bar as required for Oxygen cylinder filling . 4. High purity Nitrogen 99.99%(3ppm optional) or cylinder filling. Our Advantages: 1. Low pressure air separation.
2. Advanced technology, low energy consumption.
3. Small-scale air separation using skid-mounted design, the installation and commissioning period is short.
4. It has a rigorous testing before delivery to ensure 100% pass rate.     Process Description  1. AIR COMPRESSION Air is compressed at a very pressure of 5-7 bar (kg/cm2). Air can be compressed at such low pressure by trouble free rotary compressor (Screw / Centrifugal Type/Oil free piston compressor of advanced technology are employed). Cryogenic Liquid Nitrogen Plant Air Separation Equipment: air compressor     2. PRE COOLING SYSTEM The second stage of the process uses a low pressure refrigerant for precooling the processed air to temperature around 12 deg C before it enters the purifier. Cryogenic Liquid Nitrogen Plant Air Separation Equipment: pre-cooling system     3. PURIFICATION OF AIR BY PURIFIER The air enters a purifier consisting of twin Molecular Sieve driers, working alternatively. The Molecular Sieves remove the Carbon dioxide & moisture from the processed air before the air enters Air Separation Unit. Cryogenic Liquid Nitrogen Plant Air Separation Equipment: air purifier     4. COOLING OF AIR BY TURBO (EXPANDER) The air has to be cooled to sub zero temperatures for liquification & the cryogenic refrigeration & the cooling is provided by highly efficient turbo expander, which cools the air to temperature almost below -165 to-170 deg C   Cryogenic Liquid Nitrogen Plant Air Separation Equipment: expander     5. SEPARATION LIQUID AIR INTO OXYGEN AND NITROGEN BY AIR SEPARATION COLUMN Oil free, moisture free and Carbon Dioxide free air enters into low pressure fin type HEAT EXCHANGER where the air is cooled below sub zero temperatures by air expansion process in the turbo expander.Air gets liquefied when it enters the air separation column & gets separated into oxygen & nitrogen by the process of rectification.   Oxygen is available at the outlet of the ASU at a purity of 99.6%. Nitrogen is also available t the outlet as a second product at purity of 99.9% upto 3ppm simultaneously without loss of oxygen product. Cryogenic Liquid Nitrogen Plant Air Separation Equipment: cryogenic rectification column     6. COMPRESSION OF OXYGEN AND FILLING INTO CYLINDERS The final product in the form compressed Oxygen/Nitrogen goes to the high pressure oxygen cylinders at 150 bar or up to higher as required. This can be done by liquid oxygen pump is same models. We can use oil & water free compressor.
