| Abstract: | The hydrodynamic and mass transfer performance of 38 and 50 QH 2 mini rings were studied in a 600mm diameter column with air oxygen water system. By correlating the experimental data, equations for calculating the pressure drop, flooding gas velocity and liquid phase overall height of a transfer unit were obtained. It was shown from the experimental results that the QH 2 had much better hydrodynamic and mass transfer characteristics than that of Pall rings and Intalox saddle. |
