Using an example of ethylbenzene and diethylbenzene separation, we demonstrate that structured packing with a low specific flow resistance is an effective tool for setting up hardware and energy rectification packages. By replacing conventional plates with structured packing, the flow resistance and vertical temperature gradient are significantly lowered, providing favorable conditions for thermal coupling of the columns. Thermal coupling of the columns in a two-column setup for extraction of rectified ethylbenzene and diethylbenzene provides heating steam savings of 0.13 Gcal per tonne of diethylbenzene.
