Conference in French: Multiscale modelling for mesoscopic chemistry: the example of separation chemistry
by Jean-François DUFRECHE
4 March 2019 - 4 March 2019
France
Abstract:
Separation chemistry presented in this conference consists of separating the different chemical elements to obtain pure materials or for recycling. It implements techniques such as liquid-liquid extraction or flotation that use complex material states (microemulsions, colloidal states, foams). These are structured at the intermediate (mesoscopic) scale and this particular complexity plays a fundamental role in the separation process.
We will show how modern modelling methods can treat these systems consistently, both for equilibrium and for transport properties. From a molecular point of view, by successive average and approximations, these complex fluids can be described in a coherent way at the different involved scales. The role of numerical tools and physical principles will be particularly emphasized. We will show how these new systems are revolutionizing the macroscopic thermodynamical approaches used so far.
