For 10 years, offer the DECHEMA and Prof. Dr.-Ing. Marko Zlokarnik
together courses on mixing technology and scale up to. The issues
remain for process technicians and engineers is extremely important.
This year the courses are offered for the last time under the
direction of M. Zlokarnik.
Scale-Up for technical chemists and biotechnologists
17./18.10.2011, Frankfurt am Main
The technical chemists, chemical engineers and process engineers have
to deal generally with the technical implementation of procedures that
are linked where chemical (or microbiological), chemical changes with
the mass, heat and momentum transfer and therefore on a small scale
(laboratory or pilot plant scale) behave differently than in the large

(industrial scale). These processes are scale-dependent. To name just
a few examples - - heterogeneous reactions and the most basic
operations such as mixing and stirring, sieving and sifting, filtering
and centrifuging, grinding, drying and firing processes in various
types of furnaces are also included. It is therefore to know has
always been an understandable concern of technical chemists and
process engineers, as you have to mimic those processes in the model
to shed light on the design and dimensions to get a newly constructed
plant.
Stirring in both theory and practice
20./21.10.2011, Frankfurt am Main
The stirring is applied in both the chemical and pharmaceutical as
well as in the food industry on a large scale. The main concern
Rühroperationen the homogenization of mutually immiscible liquids,
which intensify the heat transfer between the liquid and the heat
transfer surface and the mass transfer in multiphase systems, the
stirring up of solid particles in liquids and the dispersion of
mutually insoluble liquids.
First, the general aspects of agitation, as Rührausrüstungen,
mechanical stress during stirring, stirring power, flow and turbulence
are discussed, given a brief introduction to rheology, in the
dimensional analysis and scale-up. Then stirring in detail all
relevant aspects are discussed in detail, where value is placed on
that will be presented at any stirring operation reliable sizing and
design documentation.
The lecturer
Prof. Dr.-Ing. Marko Zlokarnik studied chemical engineering, earned
his doctorate at the RWTH Aachen University in chemical engineering,
and was 35 years in process engineering R & D at Bayer AG in
Leverkusen. His work area was the design of chemical reactors for
chemical production, which moved next to the elucidation of the
fundamental work on the reaction kinetics and mixing technology to
model themselves after transfer. In the 70 years he developed a highly
efficient biological wastewater treatment technology, Bayer Tower
Biology with flotation removal from activated sludge. From 1970 to
1990 he was a lecturer at the Technical University of
Clausthal-Zellerfeld for the similarity theory, 1991 to 1994 he held
the Bayer Foundation Professor of Chemistry at the University of
Cologne. From 1979 to 1988 he served as chairman of the VDI-GVC
Biotechnology Expert Committee. He has 60 publ
