Hydrodynamic and Mass Transfer Performance of Enhanced Jet Tray
In order to satisfy the revamping of refinery and chemical equipments, a new kind of tray, enhanced jet tray (EJT), was presented. The hydrodynamic and mass transfer performances of EJT and new vertical sieve tray (New VST) were investigated with air-water-oxygen system in a stainless steel column of 1200mm internal diameter. Correlations of hydrodynamic parameters such as pressure drop, weeping and entrainment of EJT were obtained. The experimental results show that EJT has lower pressure drop, fractional weeping, entrainment and higher efficiency compared with New VST because of its special geometry characteristics.
