Abstract The equation developed by Z uiderweg [3], relating sharpness of separation in batch distillation to number of theoretical plates, reflux ratio, and holdup of the column, has been analysed. Based upon this, a method is suggested to choose the most useful combination of number of theoretical plates, reflux ratio, and holdup, in order to obtain a required separation. A nomograph is provided to simplify the calculations. Directions are given for selecting the best column out of the available ones, or for adjusting the amount of charge in case only one column is available.
