Despite the need for sophisticated instrumentation, breath figure assembly (BFA) methods are restricted to produce macroporous films on a tiny scale so far. The current study narrates the fabrication of macroporous films in hollow fiber geometry which extends to adopt the method for continuous production of isoporous surfaces from commercially available low-priced polymer materials. The fabrication of the films in the hollow fiber geometry is carried out by a co-centric quadruple orifice spinneret through which four different liquids are co-extruded simultaneously: bore fluid (to fill the lumen of the fiber), support layer solution, glycerol, and an isoporous film forming solution through the outer most orifice. The extruded entities plunge into a coagulation bath after passing a definite air gap. The implementation of the concept of diffuse-in, droplet formation, and then condense-out behavior of glycerol in a co-extrusion method of hollow fiber spinning makes macroporous film formation possible in an interminable way sidestepping the use of breath figure assembly method. Moreover, the continuous film formation by the proposed mechanism is also authenticated in flat sheet geometry by employing two casting blades in a casting machine. The structure of the films is analyzed by scanning electron microscopy (SEM).

Modern high‐performance flat sheet gas separation membranes exhibit high permeances as well as high selectivities, e.g., for CO2 separation. Novel membrane modules are desirable to transfer the intrinsic membrane performance to the process. The introduced module implements countercurrent flow, which allows for the best utilization of the required driving force, provided concentration polarization and pressure drops can be kept at bay. As such, it is different from established flat sheet modules for gas separation. The design features allow for straightforward scaling and easy adjustment to other operating conditions. During module development equation‐oriented modeling, computer‐aided engineering design and application of computational fluid dynamics for flow optimization were integrated. The prototype was investigated in a pilot plant. The experimental results reflected the simulation predictions and proved the validity of the module concept.

Die kontinuierlich wachsenden Anforderungen an Produktreinheit und ansteigende Energiekosten erfordern neue, energieeffiziente technologische Ansätze in der chemischen Industrie. Speziell die selektive Abtrennung von organischen Verbindungen aus wässrigen und organischen Mischungen wird in Zukunft eine bedeutende Rolle spielen. Die organophile Pervaporation ist eine innovative Technologie für diese Trennaufgaben. Ein Gesamtkonzept für das Design eines Membranmoduls für die Pervaporation wird präsentiert. Dieses Konzept beinhaltet die Entwicklung einer hoch‐selektiven Membran und das Design eines neuen Membranmoduls. Für die strukturierte Simulation der Trennleistung der Membran und des Membranmoduls werden drei sequentielle Modelle erstellt und in einem benutzerfreundlichen Software‐Tool implementiert.
