ABSTRACT:
Redistribution devices in a packed column are provided for mixing and redistribution of both downflowing liquid and upflowing vapor to reduce liquid to vapor concentration gradients. In one form, the vapor is redistributed by first risers directing vapor streams outwardly toward the column and second risers located adjacent the column solely directing vapor streams toward the column center.
