Ingénierie des Réacteurs Polyphasiques Innovants - IRPI (Innovative Multiphase Reactor Engineering)

IRPI develops innovative or breakthrough solutions to multiphase reactor engineering problems. The research department combines a wide range of skills: reaction engineering and catalytic reactors, fluidization, chemical vapor deposition (CVD), solids processing, advanced oxidation and sonochemistry. The fields of application of its research include chemistry, energy, new materials, environment and depollution, as well as new technologies.

Overall objectives of the IRPI department

In order to develop innovative and high-performance technological solutions that meet specific functions, the IRPI department bases its research on the study and understanding of local phenomena (hydrodynamics, interfacial transfer, chemical reaction and various physical and physico-chemical processes such as adsorption, grinding …) inside multiphase contactors. The multi-scale approaches developed by the IRPI teams are invariably based on the complementarity between experimentation (local metrology, pilot scale contactors) and modeling (phenomenological models, computational fluid dynamics). The unifying scale of IRPI is the unit operation. Models at the “micro” and “meso” scales are used to derive “average” properties, closure laws and transfer models in order to optimize the performance of the technological solutions developed. The department publishes its work in scientific journals on the following topics: Chemical Engineering (~ 30%), Materials Science & Powder Technology (~ 30%), Environmental Sciences & Engineering (~ 20%), Catalysis & Chemistry (> 10%) and Energy (~ 10%).
