The design and synthesis of thermally coupled distillation flowshees for separations of five-commponent mixtures are studied. Four types of possible configurations are identified. A universal design procedure is developed for any types of the identified configurations. Examples demonstrated that this shortcut design method can not only be used to design any types of the proposed thermally coupled distillation flowsheets, but also can give very good initialization for rigorously simulation of such configurations. The synthesis of multicomponent complex distillation flowsheets is implemented with the developed method.
