✦ Synopsis

mathematical model of a batch distillation column referring to operation conditions for which usual simplifying assumptions are not admissible is described. This model is used to resolve systems with dierent heats of vaporization and takes into account vapor hold-up, anadiabatic column and plates efficiency. This method allows to determine simultaneously evolution of the concentration variation along the column and of vapor and liquid molar flows. Model equations, described for binary system rectification are easily used for a multicomponent system.
