| Study on Hydrodynamic Performance and Mass Transfer Efficiency of Porous Material Tray |
| ZHOU Hai-ying; et al.（School of Chemical Engineering; Tianjing University; Tianjin 300072; China） |
| Abstract：A new type of porous materials tray-continuous nickel foam tray was developed in this paper. The hydrodynamic performance index-plate pressure drop, etc, was investigated by using air-water system in a column with side length of 500×500mm. The mass transfer efficiency of the tray is determined by experiment of CO 2 desorption. It was showed that the mass transfer efficiency of this unit is much higher than F1 valve tray and there is no weeping, though the plate pressure drop is higher than that of F1 valve... |
