Although suffering from low energy efficiency, distillation is still the most widespread separation technique in industry. Different means for the improvement of energy efficiency, such as heat-pump assisted and thermally coupled distillation columns, have been developed. However, the comparison of these different configurations and the identification of the most energy or economicly beneficial option for a specific separation is an elaborate task. Therefore, an efficient optimization-based method for the evaluation of the different options is proposed. In contrast to most previous approaches, the method is based on a superstructure equilibrium tray model including rigorous thermodynamics. It is therefore directly applicable to the separation of non-ideal mixtures and considers a broad range of different options for energetically intensified distillation processes. For illustration purposes the design method is applied to the separation of a ternary non-ideal mixture.
