Study of thermal behaviour of microsystems for Reaction Engineering
Comas Alvarez, Nuria
Prat, Laurent
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.
