Key features of dynamic systems for multicomponent distillation

Various aspects of the mathematical modeling for distillation of multicomponent mixtures, the general properties of dynamic systems for distillation, and the features of the simplest mathematical model based on the boundary layers and the main mass transfer resistance in each phase are under consideration. The linear gradient of concentrations in the layers is used in the model. The decisive role of the driving force, i.e., the difference between the equilibrium and working nodes represented as corresponding vectors, is also discussed.
