Abstract

A highly viscous oil was used to create oil-in-water emulsions. Rheological properties of the dispersed phase, the emulsifier, and their combination were measured to study the flow behavior. The temperature dependence of the viscosity and the influence of different mixing orders on emulsion quality were examined. Furthermore, the stability of the produced emulsions was studied. Finally, the initial emulsification process was analyzed and optimizations were suggested.

Keywords: droplet size distribution; emulsion; microstructured heat exchanger; microstructured mixer; viscosity

Yongli Li

Yongli Li received his Bachelor degree from Tongji University, Master degree from Polytech’ Savoie and PhD degree from University of Caen (joint research with University of Rouen). Afterwards, he worked as Marie Curie Research Fellow at University of Limerick. In November 2012 he joined the Thermal Process Engineering Group, Institute for Micro Process Engineering, Karlsruhe Institute of Technology (KIT) as Research Scientist. His current research is on continuous emulsification and high pressure homogenization using microstructured devices.

Iris Gerken

Iris Gerken received her Diploma in Chemical Engineering in 2012 from Technical University of Dresden. She now works on efficient and improved heat transfer in micro structures as her PhD project at Institute for Micro Process Engineering, Karlsruhe Institute of Technology (KIT).

Andreas Hensel

Andreas Hensel received his Diploma in Chemical Engineering at University of Karlsruhe (Germany). Since 2001 he has been working with the group “Liquid and Dispersed Systems”, Institute of Micro Process Engineering, Karlsruhe Institute of Technology (KIT). His research fields are liquid-liquid mixing, emulsification and homogenization with microstructured systems, especially for industrial applications.

Manfred Kraut

Manfred Kraut studied chemistry at the University of Karlsruhe. Then he worked at University of Stuttgart (Germany) in the field of adsorption on zeolites. In 1999 he started to work on micro reaction technology in Karlsruhe. He is now heading the group “Liquid and Disperse Systems” at the Institute for Micro Process Engineering of KIT. His interests lie in fast exothermic liquid phase reactions, mixing and the industrial application of micro process engineering.

Jürgen J. Brandner

Juergen J. Brandner is currently head of the Thermal Processes Department/Heat Exchange Group of the Institute for Micro Process Engineering of Karlsruhe Institute of Technology (KIT), (Germany). He is also a lecturer for Micro Process Engineering at Dresden Technical University (Germany). Heis author or co-author of about two hundred and eighty technical papers and seven technical books. After studies in chemistry he obtained a Diploma in Electrical Engineering and an Engineering Doctorate in Mechanical Engineering, both from KIT, as well as a habilitation degree from Dresden Technical University.
