Reactor Concepts - the Tools for Process Intensification

Micromixers, Micro Heat Exchangers and Minitubes/Capillaries 

Concerning micro heat exchangers, it has been found, however, that due to the long period of operation needed for heat transfer and reaction (compared with mixing) and pressure loss considerations, minitubes/capillaries are often used to 

Gas-phase operation often uses premixed gases, which have to be heated to the reaction temperature. Owing to the faster reactions for gas-phase processes, typically being on the second scale, micro heat exchangers are proper reactor solutions [9].
