Application du diagramme de Mc Cabe et Thiele aux colonnes a alimentation multiple, a un ou plusieurs soutirages lateraux et a un ou plusieurs points d'apport ou d'elimination de chaleur. Bien que cette methode soit developpee pour les melanges binaires, elle peut etre adaptee aux melanges complexes

Thermal integration of a distillation column with the background process through side exchangers (side reboilers/condensers) is important for designing an energy-efficient distillation column. Thermal integration of a distillation column through side exchangers also improves the exergetic efficiency of the column. Invariant rectifying and stripping (IRS) curves are employed for thermodynamic analysis of a distillation column. Different configurations for side-exchanger integration are evaluated based on the exergetic efficiency of the distillation process and they are also compared with feed preheating options. A novel optimal configuration curve is proposed in this paper that identifies feed composition and its thermal condition for which it is beneficial to have a side reboiler in a distillation column.

This chapter studies the tray types and their distinguishing features. The particular tray selection and its design can materially affect the performance of a given distillation, absorption, or stripping system. Each tray should be designed to give as efficient a contact between the vapor and liquid as possible, within reasonable economic limits. It is impractical in most cases to change the design of each tray to fit calculated conditions. Therefore, the same tray design is usually used throughout the column. Determining the number of theoretical and actual trays in a distillation column is only part of the design necessary to ensure optimum system performance. The interpretation of distillation, absorption, or stripping requirements into a mechanical vessel with internal components requires use of theoretical and empirical data.
