Expert Details

Chemical Extraction, diffusion, mass transfer and separation processes.

ID: 107774 Minnesota, USA

Request Expert

Expert has skills in the boundary between chemistry and chemical engineering which reflect his adaptation of laboratory chemistry to industrial practice. Expert's primary expertise is in diffusion processes, especially those for chemical separations. His research on membranes, which has produced over 50 papers, now centers on the use of hollow fibers as an alternative to packed towers for gas treating and liquid extraction. He is an authority on extractions and can answer questions regarding solid diffusion, fluid diffusion, interphase diffusion, and liquid-liquid mass transfer operations. Other expertise includes diffusion in porous solids, with applications from the decay of teeth to the action of salt on winter roads.

Expert has written over 200 articles and five books, including Diffusion, Bioseparations, and Chemical Product Design. He is particularly expert on coupled mass transfer and chemical reaction.

Expert's consulting deals mainly with diffusion and separation, especially using membranes, and includes major studies of gas treating, extraction, and reactor scale-up. Because he is an exceptionally effective classroom teacher, Expert also teaches short courses on chemical engineering.
