| Abstract: | The fluid mechanics and mass transfer property of New VST (Vertical Sieve tray Tower) in our country were summarized. The fluid mechanics property refered to pressure drops of dry trays and wet trays, weeping of hole and plate, excessive entraining, capability of single mantle dray up, and circulating plane of liquid. The mass transfer property refered to plate efficiency model, droplet size and distribution in plate space, tridimensional mass transfer in plate space. It makes out that we have thorough research in New VST and come to the top. |
