Consultancy is available to assist companies having problems with powder characterisation and the design or operation of fluidized bed processes. We offer a comprehensive and rigorous analysis of equipment and computational work as well as onsite inspections and discussions. All kinds of problems are covered whether they be for increased yield and process improvement or problematic plant, equipment or powder characteristics.
Derek Geldart is Emeritus Professor of Powder Technology in the Department of Chemical Engineering at the University of Bradford, West Yorkshire, UK, Visiting Professor of Chemical Engineering at Heriot-Watt University, Edinburgh.: HonoraryProfessor of Powder Technology at the Universities of Leeds and Birmingham and Director of Powder Research Ltd., a company dedicated to providing training and consultancy services in powder technology.
After graduating from the University of Newcastle upon Tyne in Mechanical Engineering, he studied for two further years for a Master's degree in Chemical Engineering. He then worked as a Chemical Engineer for six years in Research and Development for the United Kingdom Atomic Energy Authority, in various locations, before joining the University of Bradford.
He started his research into fluidization in 1967 and was awarded a Ph.D. in 1971 for a dissertation which included a diagram for characterising powders according to their fluidization and aerated flow behaviour. This is now used world-wide, and is known as the Geldart Fluidization Diagram. He has a particular interest in fine powders such as cracking catalyst and has won major research grants from international oil, pharmaceutical, and chemical companies, and from other funding bodies such as EPSRC, EPRI, and IFPRI. He has more than 120 publications in books, academic journals, and conference proceedings and, at the 8th International Engineering Foundation Conference on Fluidization in 1995, he was awarded a medal in recognition of his outstanding contribution to the technology over the past 25 years. Professor Geldart, who is a Fellow of the Institution of Chemical Engineers, also acts as a consultant for many well-known companies in the UK, Continental Europe, and the USA. He is a member of the Editorial Board of Powder Technology, an International Journal on the Science and Technology of Wet and Dry Particulate Systems
His activities include:
•designing and monitoring experimental programmes to support the development of new plants processing powders as well as improvements in existing commercial units
•analysis and evaluation of data in fluid bed plants experiencing operational problems
•acting as an expert witness in patent cases
•running intensive two to four day courses both within companies and in cooperation with ParticlesCIC of Leeds Universiiy
