Liquid vapor contact column

摘要

A liquid-vapor contact column comprising a column shell and one or more beds of structured packing located within the column shell. Each bed of structured packing includes a plurality of vertical stacks which are formed of at least two upper and lower levels of structured packing. The structured packing is partitioned to form the vertical stacks. When the structured packing is formed from corrugated sheet material, the vertical stacks can also be spaced from one another with the corrugated sheets making up the structured packing rotated 90 DEG with respect to boarding vertical stacks of structured packing. The partitions or the rotated arrangement of the packing inhibit liquid migration in a transverse, horizontal direction of the column. This promotes constant liquid and vapor flow characteristics through each of the vertical stacks of structured packing to resist widespread liquid channeling throughout the column.
