| Brief content | Taylor-Couette flow is a gap phenomenon. Depending on the physical properties of a liquid and the rate of rotation of a shaft in a cylinder up to 74 different flow patterns may form. Although well investigated Taylor-Couette contactors are rarely applied in industry. Application of Taylor-Couette Two Phase Flow in liquid-liquid extraction is still limited to research activities, although spiral flow as well es banded flow may well contribute to easy to operate processes. Our group has investigated the effect of the gap ratio (the ratio of shaft diameter to cylinder diameter) on hold-up, mean drop size of the dispersed phase and residence time distribution. The gap ratio was varied between 0.5 and 0.8. The specific flow rate of the dispersed phase and the continuous phase was varied between 20 m/h and 40 m/h. The results confirm applicability of Taylor-Couette Two Phase Flow in liquid-liquid separations. |
