Green reactors

The advantages and disadvantages and the and design parameters that need to be considered when selecting microreactors to achieve process intensification (PI) are discussed. Oscillatory flow mixing (OFM) reactor, which includes oscillation of fluids using an external oscillator, is characterized by plug-flow RTD, high heat transfer, and short reaction times. A plate-type reactor combines the high-heat-transfer capabilities of plate heat exchangers with the mixing of microreactors into a single unit, and is designed such that reactants can be injected at different locations along the flow path. The spinning tube-in-a-tube (STT) reactor is capable of creating sub-Kolmogoroff and near-Kolmogoroff eddies, which can reduce reaction time. The spinning disc reactor (SDR) has a very small reactor holdup, such that very hazardous reactions can also be carried out.
