Distillation is the most common separation technology utilized in the petroleum and chemistry indus-tries.Due to the wide usage of the distillation column,even a small improvement in performance may result in significant energy cost savings.Aiming to improve the hydrodynamics and mass transfer perfor-mance,the flow-guided trapezoid spray-packing tray (FTS-PT) was designed by combining flow-guided holes and trapezoidal caps with structured packing.And the experimental measurements of the FTS-PT,including pressure drop,clear liquid height,weeping,entrainment,and tray efficiency,were con-ducted in a 500 mm diameter plexiglass column with the air-water-oxygen system.Moreover,the per-formance of the FTS-PT was compared with that of new vertical sieve tray (New VST) and F1 valve tray.The results show that FTS-PT has a significant advantage in pressure drop,entrainment,and capac-ity.Furthermore,the calculation model of the pressure drop was derived and used for the FTS-PT with a relative deviation of less than 5％.
