A partir d'une représentation analytique simple d'un procédé comportant des opérations de transfert et/ou de réaction, on relie l'efficacité du procédé au rapport de 2 constantes de temps : le temps de passage du fluide et le temps caractéristique d'opération. L'analyse de l'évolution du temps caractéristique d'opération en fonction des dimensions caractéristiques du système montre, en fonction de la nature de l'opération, comment la microstructuration permet d'améliorer les performances et/ou de miniaturiser le procédé étudié.
Based on a simple model of a process involving transfer operations and/or reactions, this study relates the process efficiency to the ratio of two time constants: the space time of the fluid and the characteristic time of the operation. Further analysis of the variation of the characteristic time as a function of the characteristic dimensions of the system demonstrates how microstructuration enables the improvement the process efficiency and/or the miniaturization of the process, depending on the main operation involved.
Keywords: Characteristic times, Microstructuration, Process, Transfer, Reactor, Intensification, Miniaturization
