Abstract This paper presents an overview about the state of the art in the development of structured packings for distillation applications. The focus is on highlighting different approaches, including heuristic development cycles, the development of new packing structures, 3D printing as a tool for manufacturing, and computational fluid dynamics to determine the packings’ performance through use of simulations. Special attention is given to the recently upcoming application of shape optimization algorithms to improve structured packings. It is evaluated how this approach fits into the conventional development process, what the limitations of current shape optimization approaches are, and how they can impact the performance of structured packings. Finally, an opinion about the next steps in the development of shape optimization algorithms for packing development is given.
