Problems with wash tower packing
Thread Content
We plan to use the existing tower of the unit as a washing tower, but it was originally a distillation tower with structured packing made of wire mesh. Can this type of packing be used for washing? Should it be changed to loose Raschig ring packing?
Isn’t the efficiency of screen fillers higher? It just requires a proper distributor
It’s not necessary; the effect is the same. It’s just that the spray volume and return flow rate need to be calculated.
It’s not necessary; if the spray volume and return flow do not match, resulting in excessive resistance, it is possible to remove some of the packing.
It can be used; no problem. A well-structured elastic range provides greater efficiency. Confirm the model and the amount of gas and liquid under the current operating conditions to see if it meets the requirements. The distributor and redistributor have a significant impact on the washing effect, and should be recalculated for new operating conditions.
It’s better not to use structured packing. The reason we use loose packing is to save costs. If there’s a better option available, then we should use that one; however, the amount of packing needed still needs to be calculated
What, do you still want to pass off inferior products as good ones? Regular packing materials have a better efficiency than Raschig rings; it’s just that their initial investment cost is higher
