In this study, a systematic energy integration of the distillation separation system is developed to get minimum energy consumption with less capital cost. The optimization is carried out in terms of distillation sequence, process intensification, pressure, temperature & composition of the column, no.of stages, and feed tray location. The extent of the energy reduction depends on the composition of the feed as well. The above-explained approach has been utilized in a real time case, which consumes 20% less energy than that of presently employed conventional distillation method for the chosen ternary system. This new method also requires less capital cost for a green field project. The paper also advises general heuristics to employ a particular distillation sequence for separating a ternary mixture system. The methodology employed in the study, can also be utilized to optimize four-component mixture systems.
