For the application of microreactors in industrial processes, more scaling‐up strategies are still required except of the original concept, the numbering‐up. A more maneuverable and economic approach, combining both similarity‐up and numbering‐up, is introduced as an example for an innovative strategy. CFD simulation is also applied to assist analysis and optimization of fluid distribution. Based on this concept, named similarity‐up + numbering‐up + simulation, a pilot‐plant microsieve dispersion minireactor used to proceed the reaction of cyclohexanecarboxylic acid and oleum is designed and tested experimentally. With the contribution of similarity‐up, the treating capacity of the core unit is significantly increased. Ten parallel units are integrated to form a correspondingly enhanced capacity of the microreactor which exhibits low pressure drop, stable operating performance, and excellent main product selectivity.
