Abstract

The results of experimental determination of the amount of liquid on the walls of structured packing are presented. Using snap-off valves placed in the reflux line and in the line of heavy fraction drain from the column to the steam generator enables determination of the total amount of liquid staying between the valves at the moment of cut-off. With a preliminary calibration of the volumes between the snap-off valves and not included in the packing, it was possible to calculate the amount of liquid held by the packing for a given operation mode of the column. The surface of the packing known, it was possible to calculate the average thickness of the liquid film located on the walls of the packing.

蒸馏塔规整填料表面持液量的实验测定

摘要

给出了规整填料壁上液体量的实验测定结果。使用放置在回流管线和从塔到蒸汽发生器的重馏分排放管线中的截止阀可以确定在截止时刻停留在阀门之间的液体总量。通过对截止阀之间的体积和不包括在填料中的体积进行初步校准，可以计算出在给定的色谱柱操作模式下填料所保持的液体量。已知填料的表面，可以计算位于填料壁上的液膜的平均厚度。
