Report examines the example of a ternary mixture of distillation. A mixture of three substances is to be separated by means of distillation. Afterwards, the ingredients (benzol, toluene and o-xylene) are supposed to be available in almost pure form. The possibility of fractional batch distillation is presented in this document for this purpose. Batch distillation also allows the economic separation of smaller quantities of substance mixtures with at the same time high flexibility regarding the design specification. Due to the temporal dependence of the distillation process caused by the substance-specific boiling range, batch distillation is a discontinuous distillation process. A batch column with 5 collection tanks is used to accumulate the respective distillate. A so-called time switch between the tanks and the column ensures allocation to the respective product tank.
