摘要：

Process intensification by microstructuration. 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.
