These reactors are still the workhorses of the chemical industry\, with particular focus on stirred tanks. The chemical industry in Europe is one of the sectors performing better in terms of reducing its footprint. The energy intensity of this industry was halved in 26 years. One of the m ain areas of optimization is on mixing operations\, particularly those rel ated to chemical reaction and heat transfer. So\, the scenario on the chem ical reactors has been changing with the introduction of more efficient re actors\; many developed from CFD studies.\n\nIn the 90s early 2000s\, ther e was a trend on research towards the microsizing of chemical reactors. Th e microreactors is still a very active research field putting forward tech nical solutions for fast chemical reactions\, or extremely endo/exothermic processes\, where mass and heat transfer become limiting steps. Nonethele ss\, the advantages in most industrial applications are overridden by the operational problems. Prof. Hessel\, one of the main promoters of microrea ctors put it best by stating: “as small as (beneficially) needed\, but n ot as small as possible.”\n\nAt FEUP\, research on mixing has been provi ng that mesosized reactors\, such as opposed jets mixers and NETmix reacto rs\, can outperform microreactors without most of the associated operation al problems. In this talk\, I will address the issues of scale in chemical reactors and illustrate it with results from research on mixing and indus trial cases.\n\n\n\nRicardo Santos graduated in Environmental Engineering at Universidade de Aveiro in 1996 and got his PhD in Chemical Engineering from Faculty of Engineering of University of Porto (FEUP) in 2003. The PhD was made at LSRE and the research topic was: Mixing Mechanisms in Reactio n Injection Moulding. After the PhD he was Post-Doc for one year\, in an i ndustrial project on the rheology of Self-Compacting Concrete. Since 2006 he has been at the LSRE-LCM Associated Laboratory as Research Assistant re searching on the field of mixing in chemical and biological reactors. One of his main fields of interest is the mixing in reactive polymerization re actors. In 2013 he was one of the founders of a spin-off company\, MICE-mo lds\, that is taking to industry the main findings of the research on Reac tion Injection Moulding at the LSRE-LCM. Recently\, he has been researchin g on mixing in NETmix reactors\, in single-phase and multiphase flow for e nvironmental applications. Since 2017 he is the leader of a research proje ct funded by FCT on this topic (HXmeso).\n\n\n\n \;\n\n[Host: Joaquim Faria\, Associate Laboratory\, LSRE-LCM]\nImage credits: Ricardo Santos ATTACH;FMTTYPE=image/jpeg:https://deq.fe.up.pt/wp-content/uploads/2020/12/ mesosacaled.png END:VEVENT END:VCALENDAR
