Distillation of benzene-toluene (50/50) mixture requires 20 equilibrium stages plus a partial reboiler. The liquid viscosity determined at the feed-stage condition of 220F, Mpenzene = 0.1 cP and Mtoluene 0.1e cP and the relative volatility at the top and the bottom of the column is 2.52 and 2.25, respectively. Estimate E, the number of actual plates required, and the column height, assuming 24-inch tray spacing with 4 ft above the top tray for removal of entrained liquid and 10 ft below the bottom tray for bottoms product surge capacity, using a) The Drickamer-Bradford Drickamer and Bradford Correlation, E = 13.3 - 66.log() b) O'Connell correlations O'Connel correlation: E. = 50.3(a)-0.226 Distillation of benzene-toluene (50/50) mixture requires 20 equilibrium stages plus a partial reboiler.
