  • Cryogenic air separation system for feed air flow disturbances
    Patent number: 5950455
    Abstract: A cryogenic air separation system wherein separation inefficiencies resulting from feed air flow disturbances due to discontinuous prepurifier operation are reduced or eliminated by inhibiting column liquid drainage during such disturbances using mesh packing having interspacial regions which hold up the liquid during the disturbances using surface tension.
    Type: Grant

  • Cryogenic rectification system with serial liquid air feed
    Patent number: 5878597
    Abstract: A cryogenic rectification system for the separation of feed air wherein at least some of the feed air is liquefied upstream of the separation columns, all of the liquefied feed air is introduced into a higher pressure column, and then a portion of this liquefied feed air is withdrawn from the higher pressure column and in serial fashion introduced into a lower pressure column.
