Expert has extensive knowledge of mixing operations needed in the chemical, petrochemical, and biochemical industries. His knowledge includes the proper selection of effective mixing geometries and the power requirements needed by a mixing unit in either laminar or turbulent applications. He is proficient in mixing and mixing times by impeller, jet, feed streams, and gas sparging in batch, fed-batch and continuous-flow systems, which may be either Newtonian or non-Newtonian fluids and includes viscoelastic fluids. He teaches one- and three-day in-house short courses on mixing.
Expert has significant consulting experience on pilot plant studies and scaleup methods. He provides basic concepts and practical advice on how to perform pilot plant studies and consults on improving and justifying a pilot plant study. Other key issues covered in his work include establishing viable process objectives, applying design heuristics, determining optimum conditions, and translating clients' processes between different scales. He teaches one- and three-day in-house short courses on pilot plant studies, has written a book on the subject, has reviewed the technical literature on methodology used, and has reviewed scaling procedures and methods of several companies.
Expert is proficient in multiphase processing for the chemical process industries (CPI). He has conducted studies in the areas of solid suspension, sludge suspension, gas-liquid contacting, and liquid-liquid dispersion. Other studies have included void minimization in composites, mass transfer in aerated agitated tanks, power consumption in a mixer, impeller flooding, distributor design, airlift pumps, and draft tubes.
Expert also has significant knowledge and consulting experience in grinders and crushers, filtration and drying and dryers as would be used in the production of fine chemicals. He can teach one- to three-day short courses in these areas.
Additive color mixing involves color measurement and mixing. In his research, he has studied the measurement of color and written several papers on the subject. He specialized in mixing earlier in his career.
Central to the process of adhesive manufacturing is mixing. Mixing times and production rates in industry can be improved. Another aspect is the rheological characterization of the material and making sure that mixing does not destroy or significantly change the rheology.
Agitation is the subject of his two books involving designing industrial mixing processes and fluid mixing in agitated tanks.
Expert is a Professor of Chemical Engineering who has taught through the curriculum except for kinetics. He has also educated himself in all areas of unit operations, including solids.
Mixing is often central to chemical reactor design. Understanding how material meets to react becomes a highly significant concern on scaleup. Laboratory studies do not provide such insight.
Solid mixing is very similar to liquid mixing. In some cases, such as free flowing powders, the same theory and methods can be applied. When non-free flowing powders, semi-solids, and pastes are mixed, more direct mixing methods are needed. Some direct mixing methods are co-kneaders, extruders and mullers.
Expert reviewed powder-liquid mixing methods for many many companies, and suggested improvements to improve profitability.He reviewed screening operations and made suggestions to improve operations. Expert reviewed chemical reactor designs for numerous companies.
