Title
Concept of Extents for Chemical Reaction Systems–Methodology and Applications
Abstract: Reliable models play a key role in the analysis, monitoring, control and optimization of chemical reaction systems. However, reliable modeling of reaction and mass-transfer phenomena is particularly challenging due to the coupling of reaction and transport phenomena. This talk introduces novel tool that facilitates the modeling and the analysis of open homogeneous and heterogeneous reaction systems. The main contribution is a procedure for computing the extents of reaction and mass transfer from concentration measurements in reactors with inlet and outlet streams, that is, not necessarily batch reactors. The strength of the concept of extents is its ability to decouple the various rate processes in a dynamic system. As a result, selected rate processes can be investigated (that is, analyzed, identified, quantified, controlled or optimized) independently of the other dynamic effects in the system. It turns out that the concept of extents is useful in many applications that include data reconciliation, kinetic identification, model reduction, state estimation, rate estimation as well as control and optimization. This talk will briefly present the underlying idea of the transformation to extents and then focus on original applications dealing with data reconciliation, state estimation and rate estimation.About the Speaker: Prof. Dominique Bonvin is currently honorary Professor at the Automatic Control Laboratory of EPFL. He received his Diploma in Chemical Engineering from ETH Zürich in 1975, and his Ph.D. degree from the University of California, Santa Barbara 1980. He worked in the field of process control for the Sandoz Corporation in Basel and with the Systems Engineering Group of ETH Zürich as senior lecturer. He joined the faculty of EPFL in 1989. His current research interests include modelling, control and optimization of dynamic systems. In particular, he has worked extensively in the areas of real time optimization, jet scheduling for nonlinear flat systems, data driven methods for controller tuning and process chemometrics. He served as Director of the Automatic Control Laboratory for the periods 1993-97, 2003-2007 and again form 2012 – 2018, Head of the Mechanical Engineering Department in 1995-97 and Dean of Bachelor and Master Studies at EPFL for the period 2004-2011. He has supervised several doctoral and post-doctoral students and has more than 400 publications to his credit. He is IFAC Fellow since 2014 and is currently serving as senior associate editor for Journal of Process Control.
