Historically most chemical reactions have been performed in large reactors or in large continuous plants. The length scale of vessels utilised to confine materials has been typically of the order metres. Transport of mass and energy had also similar length scales. Micro- and milli-reactors are a recent development where the reaction takes place in a very small reactive zone and thus the materials and energy transport length scales are significantly decreased. This results to better control of the processing environment, allowing precise temperature control, excellent mixing, substantial reduction of risk for highly exothermic reactions, as well as decrease of reactor size. Such advantages also extend to other peripheral equipment, which affect processes that are critical to the reaction, such as mixing, heat exchange and separation. In fact, often process intensification arises by taking advantage of multifunctionality, i.e. when the reaction is integrated with other processes (such as heat exchange or separation). The design of intensified reactors and equipment is a chemical engineering challenge requiring new fabrication techniques and a thorough understanding of fluid mechanics. Design is aided by simulation tools, which can be used to better understand the interaction of the key processes of mass and heat transfer and reaction.

About the Speaker

Asterios Gavriilidis

Professor at UCL Chemical Engineering

Asterios Gavriilidis
Asterios Gavriilidis is Prof of Chemical Reaction Engineering at University College London. He has long standing expertise on catalytic reaction engineering, and his group has developed a range of intensified reactors for applications in bulk chemicals as well as fine chemicals/ pharmaceuticals. Since 2000 he has been working in microreaction technology and micro process engineering. This work takes advantage of unique properties of miniaturised devices and the dominance of different forces in microscale for process intensification and obtaining information under well-controlled conditions. Currently, his group is focussing on the development of microreactors and milli reactors for nanoparticle manufacturing for applications in healthcare (antimicrobial surfaces, cancer hyperthermia treatment, diagnostics). He has published >220 papers. More about Asterios Gavriilidis
