Abstract
The efficiency of mixing vapor in a countercurrent column (1) is improved by use of one or more vapor risers (6) each incorporating a mixing device (7). The method is suitable for use in countercurrent columns operating at high pressures or under vacuum. For high pressure operation a single riser is preferred positioned in the center of the distributor tray (5).
