Automatisierte Quantifizierung von Blasengrößenverteilungen in einem gerührten Luft/Wasser-System, 2013
— Authors: Panckow, R., Maaß, S., Emmerich, J. und Kraume, M. — Chemie Ingenieur Technik, 85(7): 1036-1045 Die exakte Bestimmung der Phasengrenzfläche in Gas/flüssig-Systemen ist unabdingbar für die optimierte Prozessführung verfahrenstechnischer Anlagen. Die experimentelle Studie zeigt Untersuchungen an einem Luft/Wasser-System mittels dreier Messtechniken hinsichtlich der Bestimmung der Veränderung der Blasengröße
Oxygen Absorption into Stirred Emulsions of n-Alkanes, 2012
— Authors: Ngo, T. H. und Schumpe, A. — International Journal of Chemical Engineering, 2012 (link) Absorption of pure oxygen into aqueous emulsions of n-heptane, n-dodecane, and n-hexadecane, respectively, has been studied at 0 to 100% oil volume fraction in a stirred tank at the stirring speed of 1000 min−1. The volumetric
Effective and Intrinsic Kinetics of Liquid-Phase Isobutane/2-Butene Alkylation Catalyzed by Chloroaluminate Ionic Liquids, 2013
— Authors: Schilder, L., Maaß, S. und Jess, A. — Industrial & Engineering Chemistry Research, 52(5): 1877-1885 (link) The kinetics of the IL-catalyzed reaction of isobutane with 2-butene and the size distribution of the dispersed IL droplets were investigated in a stirred tank reactor. The results were used to calculate the
Der Taylor-Couette Disc Contactor (TCDC); ein vereinfachtes und optimiertes Design von Drehscheibenextraktoren, 2014
— Authors: Aksamija, E.— Dissertation | Technische Universität Graz (link) In the present work the design of the RDC extractor, a well-established apparatus in solvent extraction, has been fundamentally simplified and optimized in terms of separation efficiency, load capacity and applicability for extraction of bio-based raw materials. Based on the Rotating Disc
Fermentation broth components influence droplet coalescence and hinder advanced biofuel recovery during fermentation, 2015
— Authors: Heeres, A., Schroën, K., Heijnen, J., van der Wielen, L. und Cuellar, M. — Biotechnology Journal, 10(8): 1206-1215 Developments in synthetic biology enabled the microbial production of long chain hydrocarbons, which can be used as advanced biofuels in aviation or transportation. Currently, these fuels are not economically competitive
A Cost-effective and Reliable Method to Predict Mechanical Stress in Single-use and Standard Pumps, 2015
— Authors: Dittler, I., Dornfeld, W., Schöb, R., Cocke, J., Rojahn, J., Kraume, M. und Eibl, D. — NEU! Übersetzung auf Hindi verfügbar Journal of Visualized Experiments, (102): 10.3791/53052 (link) Pumps are mainly used when transferring sterile culture broths in biopharmaceutical and biotechnological production processes. However, during the pumping process shear forces
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
