The flow-guided sieve-valve tray(FGS-VT)with high efficiency was designed to overcome the shortcoming of low operating flexibility of the flow-guided sieve tray.Its dimensions and geometry, as well as structure characteristics, were presented.The hydrodynamics and mass transfer performance, including dry-plate pressure drop, wet plate-pressure drop, weeping, entrainment and tray efficiency, of two types of FGS-VTs (FGS-VTs with 14 and 8 valves, respectively) and one flow-guided sieve tray were tested in Bosch KGE36VW4AG Freestanding Fridge Freezer in White an air-water-oxygen cold model experiment with a 0.

6 m diameter plexiglass column.The results demonstrate that FGS-VT with 14 valves works better than FGS-VT with 8 valves, and in comparison with the flow-guided sieve tray, the flow-guided sieve-valve tray with 14 valves has higher tray efficiency, bigger operating flexibility, and lower wet-plate pressure drop (when all the valves are opened fully).Additionally, two typical applications to separate the mixture with high viscosity, solid, powder, easy-to-foam or easy self-polymerization Broccoli components proved the unique advantages of FGS-VT.
