There is a growing interest to design and operate chemical processes for reduced energy consumption. As an example a comparison is made between the distillation of binary mixtures in a conventional distillation column, a vapour recompression system and a two column heat integrated system. For all three configurations constraint control schemes are proposed. Utility costs can be reduced with about a factor of two by using a beat integrated system.
