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.
