| Abstract: | The hydrodynamics and mass transfer performance of φ16 andφ25 QH1 mini ring were studied in a 186mmID column with airoxygen water system.By correlating the experimental data,equations for calculating the pressure drop,flooding gas velocity,flooding packing factor,wetted packing factor and liquid phase overall height of a transfer unit were obtained.It is shown from the comparison that the QH1 mini ring has much better hydrodynamics and mass transfer characteristics thanφ16 pall ring. |
