🌎 Christian Hoffmann and Jens-Uwe Repke are currently at the AIChE Spring Meeting in Dallas, TX, to present our research and network with chemical engineers from Northern America. 👨🏫 On Thursday, Christian will give a presentation on the "Experimental Investigation of the Liquid Discharge Behavior of Structured and Random Packings", a cooperation with BASF co-authored by Bernd Metzen. Much credit is also due to our former colleague Hannes Raddant, who carefully planned and carried out the experiments. 🔍 In the presentation, we show how three different packing types drain when gas and liquid load are shut down, e.g., in the event of a reboiler failure. In addition, we propose a very simple and numerically robust dynamic model that describes the experimental data with surprisingly high accuracy. 💺 Interested? Then join us Thursday in the Hilton Anatole, Senators Lecture Hall, at 10:50 a.m. We look forward to seeing you there! #TUBerlin #dbta #AIChESpring #GCPS2025 #ProcessSafety

👨🏫 At this year's Dechema Annual Meeting on Computational Fluid Dynamics in Clausthal, Tiago Campos presented a poster on “Solving challenges in the modelization of two-phase surface tension driven flows”, while our postdoc Georg Tobias Brösigke talked about “CFD as a Tool for Insights into Multiphase Flow Structures in HiGEE Separation Equipment”. 🎓 In addition to discussing our research with others, we were finally able to “officially” hand our alumni Henning Bonart his doctor's hat. Henning had defended his PhD thesis in 2021 when the Covid pandemic prohibited doctoral defenses in person. When we finally returned to normalcy, his doctor's hat had long been prepared, but ... well, time happended and it was forgotten. Thanks to Georg, this wrong has finally been corrected and Henning received his hat in the presence of his PhD reviewer Martin Wörner and a large part of the CFD community.

🎉 March 12, 2025, was a very special day for us. After more than 13 years at our group as student assistant, master's student, PhD student, and postdoc, Erik Esche successfully completed his habilitation. 👨🏫 Erik concluded the necessary formalities with a lecture on “Modeling and optimization under demand response" in which he discussed two examples: chlor-alkali electrolysis and air separation units. 🙏 We want to express our deepest grattitude to Erik for his contributions to our group - both public and internal. Among many other things, he ➡️ acquired many research projects, ➡️ designed, developed, and taught the content of several courses - especially "Process Simulation" and "Process Optimization" ➡️ supported countless PhD students when they faced challenges in modeling, simulation, or optimization ➡️ improved our internal IT structure significantly ➡️ kept our modeling platform MOSAICmodeling alive by publishing continuous updates and adding new features Although Erik has moved to the Bundesanstalt für Materialforschung und -prüfung in October of 2024, we are delighted that he will continue as lecturer for “Process Simulation” and “Process Optimization”. We will also remain close partners in research collaborations. #TUBerlin #dbta

🚀 2025 is off to an excellent start for us with many new publications! Over the holidays, we published 9 articles - either by ourselves or with great collaborators! Here are the main ideas: 1️⃣ Karsten Duch proposes a novel process design methodology and applies it to improve the reductive amination of long-chain aldehydes, achieving higher yields and selectivity in microemulsion systems, with excellent catalyst retention and long-term stability. 2️⃣ Volodymyr Kozachynskyi critically examines the practical identifiability of the NRTL model and compares various regularization methods, improving parameter estimates and predictions for vapor-liquid equilibrium data. 3️⃣ Bartolomeus H. (former master's student and now PhD candidate in Belgium) reviews the integration depth of Life-Cycle Assessment (LCA) and chemical process design. The analysis reveals considerable gaps in the state-of-the-art, but also suggests potential research avenues for the future. 4️⃣ Johann Weigelt extends the use of PLIF-I for measuring diffusion coefficients in complex fluid systems, providing critical insights into mass transfer for non-binary fluid properties and paving the way for more accurate experimental setups. 5️⃣ Muhammad Uzair Qureshi proposes a new reduced-order approach for simulating catalytic reactions that reduces computational costs significantly, offering an efficient method for kinetic model development. He demonstrates his approach for methanol synthesis from CO2 and H2. 6️⃣ Albert Gili (Dr.-Ing) explores the use of indium oxide catalysts for methanol synthesis from CO2, identifying optimal phase structures and operational conditions for improved catalyst stability and performance. 7️⃣ Emiliano Dal Molin studies 3D-printed In2O3/ZrO2 catalysts for direct methanol synthesis, showcasing how varying geometric designs impact catalyst performance, pressure drops, and degradation mechanisms under reaction conditions. 8️⃣ The researchers of the ReProvAP project provide valuable guidelines for enhancing the standardization and comparability of separation efficiency measurements in distillation and absorption columns, improving experimental reliability across industry and academia. 9️⃣ Finally, David Krone (former colleague and PhD candidate) introduces a more efficient method for optimizing process synthesis tasks using abstracted phenomena-based building blocks. Links to all articles can be found in the comments! Almost all articles are open access. #TUBerlin #dbta
