ABSTRACT:
A process for the separation of multicomponent systems containing intermediate boiling substances in separating separating columns with side discharge, the temperatures T.sub.u and T.sub.o above and below the side discharge are measured on the column or inside the column and the temperature difference T.sub.u -T.sub.o is used for controlling the side discharge. The control is carried out by constantly controlling one of the two temperatures T.sub.u or T.sub.o by the output of the evaporator or the discharge from the sump or the reflux or the removal of distillate or the reflux ratio.
