Process intensification is a new paradigm in Chemical Engineering, aiming at achieving
sustainability in the process industry, so the world’s requirements for energy and consumer
products are met without compromising those needs for future generations. Microreactor technology
is a huge step forward in the pursuit to achieve process intensification design methodologies, “doing
more with less”. The microreactor provides many benefits over conventional sized reactors used in
the process industry, such as the ability to easily control the reaction parameters, yield and
efficiency are vastly improved, mass and heat transfer rates are maximised as they are no longer
limited by diffusion.
The Laboratoire de Génie Chimique carries out investigations in microreactors for Reaction
Engineering. This study is composed of tow parts and the main objectives are:
• To establish a Liquid-liquid flow cartography for water droplets dispersed in PDMS oil in
rectangular microchannels. Flow regimes were established for a variety of flow rate pairs of
the continuous and dispersed phases. Droplet length, slug length and droplet velocity are
determined by image analysis using a micro-PIV system.
• To study the temperature profile inside a capillary tube in a heat exchanger device by an
original calorimetric method.
