“…For distillation processes, there are discrete variables, e.g., the stage number, and also continuous ones like the reboiler duty. This results in optimization problems that are mixed‐integer non‐linear programming (MINLP) problems . Additionally, the variables can be limited by constraints, which can be equality constraints h or inequality constraints g .…”

Dividing-wall columns are a well-known and proven technology to separate a ternary mixture into pure products with significant savings in capital and operational costs compared to standard two-column configurations. A consequent advancement are multiple dividing-wall columns, which allow the separation of multicomponent mixtures in one column shell. However, due to their high complexity, no practical realization has been reported yet. This paper briefly discusses the current state of the art followed by a detailed description of a robust initialization of rigorous flow sheet simulations based on V min diagrams. With the data from the simulation a multi-objective optimization can be performed. The knowledge from the simulations shall be used to build the first multiple dividing-wall column worldwide.

“…Also related to the simulation many publications address mathematical optimization of DWC. Waltermann and Skiborowski provide a good overview on common techniques . Since in distillation the optimization goals are typically contradictory, e.g., number of stages versus reflux, pareto optimization seems to be the method of choice and was successfully applied for DWC .…”

Process intensification is one of the major strategies in chemical engineering to cope with the steadily increasing demands to design and operate a chemical process as efficient and sustainable as possible. Research on this field reaches back to the middle of the last century and is still an important area of activity for chemical engineers in both, academia and practice. This contribution provides a rough overview on the history of process intensification, highlights three current examples of research (multiple dividing wall column, nanostructured core‐shell catalysts, photocatalytic reactions) and closes with a brief outlook to future activities.
