Air Separation Plant

We manufacture and supply the plants by incorporating the latest technology Cryogenic Technology in order to make them stand out among our competitors. The life span of our plants is also very high. Exceptionally designed, the products are available in different capacities and operate at a working pressure of 6 to 8 bar. Once installed, they perform for years without wear and tear. The upkeep expense is also very low so they are easy to run.

Process Description of Air Separation Plants :

1.COMPRESSION OF ATMOSPHERIC AIR : In the very first stage, atmospheric air is compressed at a very pressure of 5-7 bar (kg/cm2). Air can be compressed at such low pressure by advanced and trouble free rotary compressors.

2.PRE COOLING SYSTEM : The second stage of the process uses a low pressure refrigerant for pre-cooling the processed air to temperature around 12 deg C before it enters the purifier.

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.

4.COOLING OF AIR BY EXPANDER :The air has to be cooled to sub zero temperatures for liquification & the cryogenic refrigeration & the cooling is provided by highly efficient expander, which cools the air to temperature almost below -165 to-170 deg C

5.SEPARATION IF 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 expander. Air gets liquefied when it enters the air separation column & gets separated into oxygen & nitrogen by the process of rectification.

6.COMPRESSION OF OXYGEN &FILLING OF IN CYLINDERS : The final product in the form compressed Oxygen/Nitrogen goes to the high pressure oxygen cylinders at 150 bar or upto higher as required. This can be done by liquid oxygen pump is same models. We can use oil & water free compressor.
