Summary of Expertise: Listed with other top experts in: 
Expert has been involved in fluid agitation and mixing since 1976. Experience includes virtually all industries using agitators, including chemical, pharmaceutical, biofuel, polymer, coatings, water and wastewater, food processing, petroleum, mineral processing, etc.

Expert has designed multistage reaction systems such as polymer reactors, 3-phase clay bleaching reactors, enzyme hydrolysis, oil enzyme reactors, etc. Calculations include heat transfer, mass transfer, power draw, blend time, shear rate, residence time distribution, etc.

He has routinely scaled-up mixing systems for agitated reactors. Often the volumetric scale ratio has exceeded 1000 to 1.

Expert is heavily involved in the design of fermenters and other bioreactors. He consults on the design of pilot plant experiments to maximize useful data, interprets the data, scales up the mixing, heat transfer and mass transfer, writes equipment bid specifications, evaluates bids and can aid in start-up and troubleshooting. He can also consult on less crticial reactors and keep bidders on an equivalent basis.

Expert is first and foremost a mixing/agitation expert. When reactor mixing is critical, he can identify the controlling parameters for reactor design and scale-up. When kinetics and mixing are linked, he can aid in engineering pratical solutions to problems where ideal mixing is impossible to achieve.

He has spent his career designed fluid mixing systems for many applications including tank reactors. He can determine the mixing required and perform heat transfer calculations.

He has designed continuous flow reactor mixing systems for Nylon 6-6, starch liquefaction, starch saccharification and ethanol fermentation. For staged columns, he can calculate required mixing as well as stage efficiency and residence time distribution.

Expert has over 36 years experience in liquid mixing, including 25 years working for a major fluid agitator manufacturer and over 11 years as an independent consultant. He has encountered and solved liquid mixing applications in virtually every industry.
