| Abstract: |
| One of the most important parameters in designing of pulsed-sieve plate extraction columns is mass transfer coefficient. Because of the inaccuracy of theoretical correlations in predicting mass transfer coefficient, experimental measurement of this coefficient is of great importance. In this research, the influence of nanoparticles on mass transfer coefficient in pulsed-sieve plate extraction column has been investigated using an experimental setup. Acetic acid-water-kerosene has been selected as experimental chemical system. Mass transfer direction was made from the continuous phase to dispersed one. The nanofluids used in this research were prepared by dispersing SiO2 nanoparticles of 0.05 and 0.1 volume percent in kerosene using ultrasonication. The effects of pulsation intensity and dispersed phase flow rate on mass transfer coefficient have been studied. The results were compared with condition of no-nanoparticles in the dispersed phase. The results revealed that the presence of nanoparticles increased dynamic dispersed phase hold-up and mass transfer performance. |
