Column Internals
Collector & Redistributor
Liquid redistributors are used wherever an intermediate liquid feed is introduced into a packed column, and between packed sections, wherever liquid redistribution is required. Liquid redistributors serve several major functions as described below:
- Evenly irrigate the bed below, and at the same time, provide a uniform vapor flow to the bed above
- Mix the liquid and equalize liquid composition throughout the column cross section.
- Mix the vapor and equalize vapor composition throughout the column cross section.
- Remove liquid from the wall and redirect it toward the center of the bed, thus counteracting buildup of excessive wall flow.
- Improve the wetting of packing by splitting up any large channels of liquid flow into small liquid streams.
