| 802 | + |
| 803 | + We investigate the application of shape optimization techniques to increase the separation efficiency of structured packings in laboratory-scale distillation columns. A simplified single-phase computational fluid dynamics (CFD) model for the mass transfer in the distillation column is used. A corresponding shape optimization problem with the goal of increasing the mass transfer in the column is solved with the optimization software cashocs. The optimization yields promising results and shows a greatly increased mass transfer for the simplified CFD model. For validation, the optimized shape is additively manufactured and investigated experimentally. The experimental results are in great agreement with the simulation-based prediction and show that the separation efficiency of the packing increased by around 20 %. Hence, the proposed approach of using free-form shape optimization for improving structured packings in distillation is extremely promising and will be pursued further in future research. |
