摘要
The mass transfer efficiencies of dualflow trays with open hole areas of 20, 28 and 37 % were experimentally investigated under total reflux conditions in a 300-mm diameter distillation column using methanol-water and methanol-isopropanol systems. The results indicate that the efficiency of a dualflow tray is a strong function of the open hole area, the vapor/liquid load, and liquid properties such as surface tension and density. A fundamental model was developed to predict tray efficiency. The prediction was found to agree with the measured data to within 15.3%.
