AIR SEPARATION PLANTS USING CRYOGENIC, PSA OR MEMBRANE TECHNOLOGY. DEVELOPMENT AND FUTURE APPLICATION.

Author(s) : BEYSEL G.

Summary

THE AUTHOR COMPARES DISTILLATION, PSA AND PERMEATION FOR AIR SEPARATION. BY REFERRING TO A CRYOGENIC PLANT ADAPTED TO THE PRODUCTION OF IMPURE OXYGEN (95%), HE GIVES SOME NUMERICAL VALUES OF SPECIFIC ENERGY, AND OUTLINES THE ADVANTAGES OF DISTILLATION BUT ALSO THE ADVANCES ACHIEVED IN PSA TECHNOLOGY DURING THE LAST DECADE. HE MENTIONS MEMBRANES AT THE END OF HIS PAPER. ALTHOUGH THEIR EFFICIENCIES INCREASED BY A FACTOR 2 TO 4, THEY REMAIN LITTLE USED FOR OXYGEN PRODUCTION, WHEREAS ONE CAN FIND SOME APPLICATIONS FOR THE PRODUCTION OF AIR ENRICHED WITH NITROGEN.
