| Abstract: | The hydrodynamics and mass transfer characteristics of 16 mm improved plastical saddle P8ckings were studied by experimental methods. A comparison of our results with those of Raching Ring, Intolax Saddle or Arc Saddle of the same or similar size was made. It shows that the Dg16 improved plastical saddle packings is superior in hydrodynamics and mass transfer characteristics. The equations for calculating the pressure drop through the packed column, the packing factor, the flooding gas velocity and gas phase overall height of a transfer unit are obtained respectively by correlating the experimental data. The results calculated by the equations presented in the paper are in line with those measured experimentally, and the maximum deviation between them is within 17 %. |
