Fluidization Technology Short Course

As part of CFB-13, short courses will be offered by world-renowned fluidization experts on fundamentals of gas-solid fluidization design and operation as well as common commercial applications. This event is aimed at engineers and researchers from academia and industry who are new to the field, or would like to improve their knowledge of the field. The full day event covers topics related to fluidized bed hydrodynamics, scale-up, and modeling, as well as specific applications in the chemical/petrochemical and energy industries.

Time:  9:00am-4:00pm May 10, 2021

Course Instructors


Fluidized Bed Hydrodynamics - Prof. Ruud van Ommen

Prof. J. Ruud van Ommen is a full professor, leading the Product & Process Engineering group at Delft University of Technology. Moreover, he is director of the TU Delft Process Technology Institute. He obtained his PhD in 2001 in Delft; his dissertation dealt with detecting agglomeration in fluidized beds.  He has been visiting professor at Chalmers University of Technology (Gothenburg, Sweden) and the University of Colorado (Boulder, USA). 

In the past decade, Prof. van Ommen expanded his research from chemical reactor engineering to the scalable production of advanced, nanostructured materials. In 2011, he started an ambitious program (funded by an ERC Starting Grant) to investigate the gas-phase coating of fluidized nanopowder. This fundamental work is already leading to practical applications, funded by industry and two ERC Proof of Concept grant. It also led to the spin-off company Delft IMP. Prof. van Ommen (co-)supervised 12 postdoctoral fellows, 20 PhD students, and over 90 MSc and BSc students. He has published about 150 journal papers, of which a large part on fluidization, including review papers on measurement techniques, pressure fluctuation analysis, scaling up, and fluidization of nanopowders.

Fluidized Bed Scale-up - Dr. Ted Knowlton

Dr. Ted Knowlton is a Technical Consultant and Fellow at Particulate Solid Research, Inc. (PSRI), an international, industry-based consortium for fluidization and solids transport research. Dr. Knowlton retired as President of PSRI in 2010. He headed the Gas Technology Institute's fluidization research and consulting group for over 25 years before becoming President of PSRI. He has conducted research in high-pressure and high-temperature fluidization processes, standpipes, cyclones, gas-solid flow systems, pneumatic conveying, non-mechanical valves and is the developer of the L-valve, a nonmechanical device that controls solids flow in transport systems. Dr. Knowlton is recognized as an authority in the field of fluidization fluid-solid contacting and solids transport. He is the author or co-author of over 200 technical papers and chapters in the fields of fluidization and solids transfer, and consults extensively for industrial clients in these areas.


Reactor Modelling - Prof. John Grace

Prof. John Grace completed undergraduate studies in chemical engineering at the University of Western Ontario in 1965 and a Ph.D. from Cambridge University in 1968. From 1968-79 he was a faculty member at McGill University, then a Professor at the University of British Columbia where he was Head of Department of Chemical Engineering (1979-87), Dean of Graduate Studies (1990-96) and Director of the Clean Energy Research Centre (2008-09). He held a Canada Research Chair in Clean Energy Processes from 2001 until officially retiring in 2014.

Prof. Grace has > 670 publications including several books, >34,000 citations and an h-factor of 80. He has supervised ~120 graduate students, as well as many postdoctoral fellows and visiting scholars. Research topics include fluidized bed hydrodynamics, heat and mass transfer, reactor modeling, scale-up, combustion, gasification, capture of CO2 and SO2, biomass processing, steam reforming, spouted beds, particle removal from gas streams, and spread of contaminants.

Prof. Grace has often chaired conferences, been a consultant and served on national committees. He is a former President of the Canadian Society for Chemical Engineering and of the Chemical Institute of Canada. He was founding president of Membrane Reactor Technologies Ltd. Honours include the RS Jane Award (CSChE), Montreal Medal (CIC), Thomas Baron and Particle Technology Forum Awards of the AIChE and an honorary doctorate. He is a Fellow of the Royal Society of Canada, Canadian Academy of Engineering, Engineering Institute of Canada, and Chemical Institute of Canada. In 2013 he was named an Officer of the Order of Canada.

Fluid Beds in Chemical/Petrochemical Industry - Dr. Ye-Mon Chen

Dr. Ye-Mon is a Technology Manager at Shell Global Solutions US Inc. He has over 30 years of experience with Shell and has assumed various roles in developing and commercializing new refining, chemical and bio-fuel  processes, holding many patents in each of these areas. His current responsibilities include leading the commercialization of a new bio-fuel technology process. 

His prior experience includes serving as Fluid Catalytic Cracking (FCC) manager/technology licensing manager for US/Canada/South America regions for 10 years.  He provided technical assurance and management leadership to implement many successful major FCC revamps projects for both Shell and third-parties refineries.  He also served as Chair of American Inst. of Chemical Engineering (AIChE) Area 3B, Fluidization and Fluid-Particle System, during which he received 3 international recognitions, Innovation for Applied Catalysis Award from Inst. of Chemical Engineering, U.K., Fluidization Progress Recognition Award and Fluidization Lectureship Award from AIChE.
