Development Centre at the University of Toronto. The next course will be

Fluid Mixing: Improving Product Yield, Throughput & Quality by
Optimizing Mixing in Reactors
Course length:
3 Day Seminar: (e.g. 14-21 hours). The course has been typically 2.5
days. I leave the final 0.5 day for subjects of interest and those who don't
want to stay for that are welcome to leave. I call this session "Chalk
Talk" and we typically discuss anything of interest. It is time for the
audience to try and put me on the spot!
Course Overview:
Course focus - Fluid mixing is rarely taught at any level in any
school. Perfect mixing is always assumed. This course focuses on imperfect
mixing and the pitfalls of neglecting the influence of mixing on chemical
reactions. Introduction to the basics and in-depth coverage of topics of
interest, such as multi-phase mixing and scale-up.
The course is broken down into 12 chapters spread over 3 days. It is
presented in the form of PowerPoint presentations. Concepts are reinforced
with quizzes. Some handouts are given and recommendations to books in the
field.

industry. Most participants have college degrees, but the math and physical
concepts are presented on a basic level.
Industries: Bulk Chemical, Pharmaceutical, Fine Chemicals, Specialty
Chemicals, Cosmetics, Tank Manufactures, Mixer Manufactures, Fermentation
Equipment Suppliers, Consultants, Engineering Companies
Prerequisite: A keen interest in improving the processes at your
company or in having a better fundamental understanding of the role that
mixing plays.
