The high heat-transfer rate of micro heat exchangers raised the possibility of preparing microreactors for highly exothermic chemical reactions. Examples are oxidation reactions with molecular oxygen [11] or direct fluorination in micro falling-film reactors [12]. These appHcations impressively demonstrated that microreactors are tools for the performance of chemical reactions in reaction regimes not accessible even in state-of-the-art conventional reactors.

Micro/milli-reactors A study by ECN in Holland suggests 20 PJ savings using heat exchanger-reactors. Microreactors extend this to 25 PJ Applications in 20% of processes in the sector saving 20% of energy - 1 PJ Reduce feedstock and additives by 30% in 10% of processes saving 5-7 PJ Spill-over from fine chemicals <1 PJ...
