Semicontinuous Distillation of Quaternary Mixtures Using One Distillation Column and Two Integrated Middle Vessels

A novel semicontinuous system for the separation of quaternary liquid mixtures is presented in this work. This semicontinuous system is a process intensification technique that uses one distillation column and two integrated middle vessels to achieve a separation which would traditionally be carried out using three continuous distillation columns. The system is a theoretical extension of the conventional ternary semicontinuous process, which …
