Model-based experimental analysis (MEXA)
Many not (sufficiently well) understood processes play a major role in chemical engineering processes. Such processes, as for instance multi-phase reactions, absorption, extraction and rectification, can thus not be quantified in a reasonably accurate manner. In order to achieve a more accurate prediction of the kinetics of such processes, a sound understanding of the underlying kinetic phenomena is necessary.
The MEXA methodology, developed within the CRC 540, aims at achieving a detailed understanding of these kinetic phenomena and their interactions, represented in form of mechanistic mathematical models. Only based on such sound models, a rational product- and process design becomes feasible. This is especially true for currently not sufficiently well understood chemical processes based on biomass, as for instance in the cluster of excellence “Tailor Made Fuels from Biomass”.
A mechanistic modeling of such complex systems can only be achieved if theorists and experimenters closely collaborate, combining high resolution measurement techniques and systems-theory knowledge. Therefore, the AVT promotes the development and validation of new methods that will generate the results in small scale, but can easily be transferred to production scale. This mesoscale-view is only made possible by a lot of novel innovative approaches.
