An experimental packed distillation column was constructed and data were taken to evaluate the effects of heating sections of the column packing during the distillation operation. The experimental column was packed with carbon Raschig rings and the heating was accomplished using an induction coil. The carbon tetrachloride and benzene system was studied. Heating the packing did not increase the separation of the components but it did allow a higher flow rate through the column before flooding conditions developed. The effect of heating relative to the efficiency of a packed column was opposite to the results obtained in an earlier investigation. Reevaluation of the earlier publication indicated that the author's conclusions were based on inappropriate vapor flow rates.
