✦ Synopsis

The equation developed by ZUIDERWEG [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. RBsumB-On snalyse l'equation developpee par ZurDEawEo [S] en indiquant le rappart entre l'exactitude de separation dans la distillation discontinue d'une part et le nombre de plateaux theoriques, le rapport du reflux et le sejour dans la colonne d'autre part. En se basant sur ce qui p&&de, on propose une methode pour choisir la combinaison la plus utile du nombre de plateaux theoriques, du rapport de reflux et du sejour afin d'obtenir la separation requise. Ensuite on donne une nomographie pour simplifier les calculs. Sont donnees encore des directives pour choisir la meilleure des colonnes disponibles ou de mettre au point la quantite de la charge en cas qu'il n'y ait qu'une seule colonne de disponible.

## Abstract Using rigorous models to simulate batch distillation involves the solution of many stiff differential equations. The dimensionality of the problem also increases with an increase in the number of plates and components, which imposes limitations on the use of rigorous models. Furthermore
