EMS Webinar - Wednesday, June 7th 2023, at 4:00 PM (CET) - Maik Tepper - Rotation-in-a-Spinneret Produces Helical-Ridge-Membranes for Mass Transfer Enhancement

Title: Rotation-in-a-Spinneret Produces Helical-Ridge-Membranes for Mass Transfer Enhancement

 

Abstract:

New membrane geometries have the potential to increase mixing at the feed and permeate side to counteract concentration polarization and fouling. Such membrane geometries can be of very different architecture. Here, we address a new class of hollow fiber membranes having helical ridges. We present Helical-Ridge-Membranes produced by our Rotation-in-a-Spinneret platform technology. The used spinnerets feature customized microstructured rotating needles. The microstructured needle orifice includes two grooves to initiate ridge formation on the lumen side of the hollow fiber, while the ridges twist helically upon needle rotation. The spinneret is specifically designed such that rotating spinning parameters enable an adjustable helical ridge pitch. Ridge formation and ridge shape strongly depend on rotational speed. The latter affects characteristic membrane properties such as membrane permeability and molecular selectivity. The helical ridges induce secondary flow in the lumen of the hollow fiber membranes, proven by experimental and simulative investigations. Ultimately, we will present results from filtration and gas–liquid membrane contactor applications to uncover their effect on mass transfer enhancement.

 

Biography:

I studied mechanical and chemical process engineering at RWTH Aachen University in Aachen, Germany. Here I devoted myself to membrane technology at an early stage. In my Bachelor Thesis, I developed hollow fiber membranes featuring a sinusoidal inner diameter. Afterwards, I researched for my Master Thesis abroad in Melbourne, Australia at CSIRO and Monash University in Matthew Hill’s group. I integrated MOFs into thin-film composite gas separation membranes made of PTMSP to control physical aging processes.

Back in Aachen, I did my Ph.D. in Matthias Wessling’s group. My core research was all about the topic "Turbulence Promoting Microstructures inside Hollow Fiber Membranes by a Rotation-in-a-Spinneret Process". More in detail, I developed microstructured rotating spinnerets using 3D printing techniques. With these spinnerets, I was able to produce membranes with helical ridges or static mixers in the lumen of the hollow fiber. These membranes proved to enhance mass transfer in filtration and gas–liquid membrane contactor applications. Now, I work as an R&D Engineer in healthcare at Baxter striving to improve membrane-based products for kidney care.

Research Assistant/Associate in Chemical Engineering (Membranes), Newcastle University, UK

  • Job type: Postdoctoral fellowship (a 1-year initial appointment and possibility of extension up to late 2026)

  • Location: Newcastle university, UK

Position: Research Assistant/Associate in Chemical Engineering (Membranes)

 

This position is available in one of the UK’s prominent chemical engineering research groups with Prof. Ian Metcalfe, FREng and Dr Greg A. Mutch. We are looking for a talented individual to work in the area of supported molten-salt membranes and their application to carbon dioxide separation and reaction engineering (e.g., Energy Environ. Sci., 2020, 13, 1766-1775 and J. Mater. Chem. A, 2019, 7, 12951-12973).

Supported molten-salt membranes offer the opportunity to bypass traditional limitations of membrane separation processes by providing both high permeability and high selectivity in a single membrane. Their potential applications range from flue gas carbon dioxide capture to water-gas shift reaction engineering.

Your role will be to fabricate and characterise supported molten-salt membranes, using our synthesis and fabrication laboratory, automated membrane gas permeation measurement facilities, and (typically via collaboration) cutting-edge characterisation techniques (diffraction, tomography, microscopy, spectroscopy, surface area and porosity analysis etc). Thus, to fulfil the deliverables of the project, you will work closely with internal and external stakeholders in the EPSRC Programme Grant, SynHiSel.

You should be enthusiastic in the discipline, committed and motivated, and have an aptitude for independent working as well as working as part of a diverse, interdisciplinary team.
