For many reactions, the microstructured mixers are simply followed by tube reactors, e.g., double-mantled tubes or shell-in-tube heat exchangers. The benefit from mixing in combination with the benefits of the continuous-flow process through the tube give process intensihcation, while providing reliable operation, especially when for larger volume flow ranges.

The main difference of microstructured reactors from the classical continuous-flow reactors consists in a laminar flow regime of the fluids (liquid and gases). The laminar flow regime is defined by dimensionless number, that is, the Reynolds number Re (Equation 1.1), which depends on the velocity u, the density p, the traveled length I, and the viscosity r] of the fluid ...
