COMPARISON BETWEEN O2 AND N2 PRODUCTION AT LOW PRESSURE AND HIGH PRESSURE AND SPECIAL ISSUE ON ARGON RECOVERY.

Author(s) : PETIT P.

Summary

COAL GAS GENERATION REQUIRES LARGE TONNAGE OF OXYGEN GENERALLY AT VERY HIGH PRESSURES (UP TO 10 MPASCALS). NITROGEN IS ALSO REQUIRED FOR THE INERTING OF THE PRODUCT GASES TREATMENT UNIT, BUT IN SMALLER QUANTITIES. COMPARISON HAS BEEN MADE BETWEEN: A CLASSICAL FRONT END PURIFICATION AIR PLANT PRODUCING LOW PRESSURE OXYGEN WHICH IS COMPRESSED TO THE REQUIRED PRESSURE BY COMPRESSOR AND A FRONT END PURIFICATION AIR PLANT EQUIPPED WITH AN OXYGEN PUMP, LIQUID OXYGEN BEING PUMPED UP TO AN INTERMEDIATE PRESSURE, THEN VAPORIZED BY HEAT EXCHANGING WITH A SMALL FRACTION OF PROCESS AIR UNDER HIGH PRESSURE. OXYGEN WILL BE BOOSTED UP TO THE FINAL PRESSURE BY COMPRESSOR.
