The dissertation “A Heuristic-Numerical Approach to the Selection and Design of Membrane Separation Systems” by Götz Krabbe develops a systematic methodology for selecting, evaluating, and designing membrane separation processes. The research combines expert knowledge, database information, and numerical calculation methods to identify suitable membrane technologies for different separation tasks. The study examines reverse osmosis, nanofiltration, ultrafiltration, microfiltration, pervaporation, vapor permeation, and gas permeation. Decision-making rules based on the physicochemical properties of feed components are established to assess process applicability and separation performance. Simplified calculation methods are developed to estimate membrane area requirements, material flows, energy balances, and operating costs. The methodology is implemented in the computer-assisted consulting system MEMPERT and integrated into the PROSYN process synthesis software. Its practical applicability is demonstrated through an industrial separation problem involving methyl ethyl ketone synthesis. The findings provide a foundation for evaluating the technical and economic feasibility of membrane separation technologies and integrating them into chemical production processes.
