Research progress of micromixers and their performance

In recent years many activities have been focused on the microchemical engineering process for the minimization of chemical engineering.The present work is spent doing development and research on micromixers and their performance.The application prospect of the micromixers in the chemical reaction,separation process and heat transfer is discussed.The advantages of higher efficiency,less contact time,low energy consumption,easy operation and control,simple equipment and better safety is concluded,while the disadvantages lie in the higher processing cost,low capacity and clean system requirement are analyzed.It is pointed out that to develop higher and newer microprocessing techniques and to develop micromixers capable of handling solid materials with a big production capacity and self-cleaning is in urgent need.
