THE PROCESS
FREE ATMOSPHERIC AIR IS SUCKED IN BY A MULTI STAGE AIR COMPRESSOR THROUGH A FILTER AND COMPRESSED TO WORKING PRESSURE. THE COMPRESSED AIR IS THEN PASSED THROUGH A PURIFICATION SKID FOR PRE-COOLING, REMOVAL OF DUST, HYDROCARBON, MOISTURE AND CARBON DIOXIDE. THIS PURIFIED AIR THEN ENTERS TO COLD BOX AND PASSES THROUGH FIRST HEAT EXCHANGER, WHERE IT IS COOLED BY THE OUTGOING NITROGEN AND OXYGEN. PART OF THIS COOLED AIR THEN PASSES THROUGH AN AIR EXPANDER AND OTHER PART THROUGH THE SECOND HEAT EXCHANGER. BOTH AIR EXPANDER & SECOND HEAT EXCHANGER HELP IN COOLING DOWN THE AIR FURTHER, WHICH IS FINALLY RELEASED TO THE BOTTOM OF THE RECTIFICATION COLUMN FOR FRACTIONAL DISTILLATION.
THE RECTIFICATION COLUMN IS DIVIDED INTO TWO PARTS LOWER COLUMN AND UPPER COLUMN. IN BETWEEN LOWER AND UPPER COLUMNS THERE IS A CONDENSER WHICH ACTS AS A REFLUX FOR THE LOWER COLUMN AND AS RE-BOILER FOR THE UPPER COLUMN. BOTH OXYGEN & NITROGEN ARE REMOVED BY SEPARATE PIPELINES, COMPRESSED AND PASSED THROUGH HEAT EXCHANGERS FOR COOLING THE INCOMING AIR DIRECT TO FILLING MANIFOLDS.
