This is a presentation on mixing and continuously stirred tank reactors (CSTR). Three radically simplifying ChE assumptions are that gasses are ideal, processes run at steady state, and stirred tanks are perfectly mixed. Real processes are full of saturated gasses, time varying operations, and complex mixing problems. In this short introduction, a technical definition of mixing is used as a framework to illustrate interesting industrial mixing problems in pharmaceutical process development, nuclear waste clean-up, bioreactors, cosmetics and food production. Participants will leave with tools to identify mixing sensitive points in a process before they become mixing problems.

Dr. Suzanne Kresta

Suzanne Kresta joined the University of Alberta in 1992, after completing a doctorate at McMaster University. She has been an active member of the North American Mixing Forum, most notably serving as co-editor of the Handbook of Industrial Mixing (Wiley, 2004), as well as chairing various conferences and serving on the executive council. She was the winner of the NAMF Award for Excellence and Sustained Contributions in 2004.

Dr. Kresta's research interests lie at the interface between the fluid mechanics in a stirred tank, and achieving desired mixing results. On the fluid mechanics...Read more
