Mass transfer and chemical test reactions in the continuous flow rotor-stator mixer

Resumo

This work is on mass transfer in liquid-liquid two-phase systems. To study mass transfer in the continuous flow in-line rotor-stator mixer, a method based on experimental determination of the product distribution of a set of complex chemical reactions has been applied together with drop breakage experiments. Experiments were carried out using the high-shear rotor-stator Silverson mixer for both drop dispersion and intensification of mass transfer. Volume fraction of organic phase was in the range between 0.01 and 0.015. The product distribution of complex reactions was determined based on high-performance liquid chromatography measurements. The drop size distribution was measured with the Malvern MasterSizer just after the process. Results of modeling of mass transfer with chemical reaction were used to characterise energetic efficiency of mass transfer.
