Determination of Particle Size Distributions in Multiphase Systems Containing Nonspherical Fluid Particles, 2015
— Authors: Panckow, R., Comandè, G., Maaß, S. und Kraume, M. — Chemical Engineering & Technology, 38(11): 2011-2016 The presented results are obtained by means of an automated image analysis software capable of measuring particle diameters in photographs taken in situ by a 2D photo-optical measurement device. Initially, the applicability
Role of bubble size for the performance of continuous foam fractionation in stripping mode, 2015
— Authors: Hofmann, A., Schembecker, G. und Merz, J. — Colloids and Surfaces A: Physicochemical and Engineering Aspects (473), S. 85-94 (link) The surface activity of amphiphilic molecules such as proteins lead to an affine adsorption at gas–liquid interfaces. Using this physicochemical property for separation like in foam fractionation these amphiphilic
The Taylor-Couette Disc Contactor: A Novel Apparatus for Liquid/Liquid Extraction, 2015
— Authors: Aksamija, E., Weinländer, C., Sarzio, R. und Siebenhofer, M. — Separation Science and Technology 50(18):2844-2852 (link) In the present project, the design of the Rotating Disc Contactor (RDC) has been fundamentally simplified and optimized in terms of separation efficiency, load capacity, and suitability for downstream processing of bio-based
Dispersion conditions and drop size distributions in stirred micellar multiphase systems, 2016
— Authors: Hohl, L., Paul, N., und Kraume, M. — Chemical Engineering and Processing, 99: 149–154 (link) Micellar multiphase systems can be applied to enable reactions like the hydroformylation of long-chained olefins. These liquid/liquid systems combine advantages of homogenous catalysis like high and specific yield or mild reaction conditions with
On droplets size distribution in a pulsed column. Part I: In-situ measurements and corresponding CFD–PBE simulations, 2016
— Authors: Amokrane, A., Maaß, S., Lamadie, F., Puel, F. und Charton, S. — Chemical Engineering Journal, 296: 366–376 (link) The pulsed column is one of the most used contactors in solvent extraction processes, especially in the nuclear fuel treatment industry and for hydrometallurgical applications. The optimisation of solvent extraction operations
Quantifizierung der hydromechanischen Beanspruchung von Pumpen auf tierische Zellen mittels des nicht-biologischen Modellsystems Emulsion, 2016
— Authors: Fries, T., Dittler, I., Blaschczok, K. , Löffelholz, C., Dornfeld, W., Schön, R., Drews, A. und Eibl, D.— Chemie Ingenieur Technik, 88(1-2): 177-182 Zur Quantifizierung der Beanspruchung durch die Zentrifugalpumpe PuraLev® 200SU wurde der mittlere Sauter-Durchmesser des Modellsystems Emulsion in Abhängigkeit des massenspezifischen Leistungseintrages ermittelt. Anschließend wurde mit ausgewählten
Analysis of physical properties, dispersion conditions and drop size distributions in complex liquid/liquid systems, 2016
— Authors: Hohl, L., Schulz, J., Paul, N. und Kraume, M.— Chemical Engineering Research and Design, 108: 210-216 (link) Tunable multiphase systems can be applied for the hydroformylation of long-chained olefins. These reaction systems enable highest yields and fastest separation processes under three phase operating conditions. However, little is known about
Gas bubble induced oil recovery from emulsions stabilised by yeast components, 2016
— Authors: Heeres, A. S., Heijnen, J., van der Wielen, L. A. M. und Cuellar, M. C. — Chemical Engineering Science, 145: 31-44 (link) In the search for advanced biofuels, microorganisms have been developed that make and secrete long chain hydrocarbons, resulting in a four phase fermentation mixture (cells, aqueous
