ASSEMBLY OF DOWN-PIPE AND TRAY FOR TREATING TOWER UTILIZING CATALYTIC MEDIUM AND METHOD FOR MIXING DISCHARGED LIQUID AND STEAM FROM DOWN-PIPE

摘要

PURPOSE: To obtain a method for an increased downcomer-tray-vapor-stream utilizing catalyst by providing a series of uniformly raised active-inlet-region- panels which is fixed below a downcomer including catalyst bundles and effectively injecting vapor streams into liquid streams utilizing an excellent vapor- liquid-processing performance of the panel. CONSTITUTION: An improved downcomer-tray assembly for a process column 10 utilizing catalyst media comprises a series of uniformly raised active-inlet- region-panels 51 which is fixed below a downcomer 53, 69 including catalyst bundle 400. The panel 51 has a plurality of apertures. One has a fluidizing feather. The apertures are arranged below a catalyst-downcomer assembly and the panel 51 provides an effective vapor injection into a liquid stream establishing the more excellent vapor-liquid processing performance. And also an excess vapor stream from a downcomer below is discharged through the panel 51. Thereby a method for an increased downcomer-tray-vapor stream utilizing catalyst media is obtained.
