Summary of Expertise:

Listed with other top experts in: 

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.

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.

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.
