Is the selection of packing for a wet flue gas desulfurization tower highly unreasonable? Everyone, please help take a look (there are pictures)

Later, the owner demolished it, saying that the obstruction was too great; why not use other bulk fillers?

This is a structured packing type; it offers higher efficiency than ordinary Boulton rings or Raschig rings, but its application is limited – it cannot be used in environments with very dirty media or in media prone to scarring

Lasi rings belong to the obsolete type, while Ball rings are commonly used as random packing materials. It is recommended to consider using Larue rings, which feature flanges added on top of Ball rings, offering higher efficiency. Regular packing materials are more suitable for applications that require cleanliness, minimal foaming, and high efficiency

This type of structured packing is actually a highly efficient type of packing, but the choice of packing still depends on the characteristics of the process flow. I know that in some desulfurization towers, spray irrigation is used directly without any packing, and the results are quite good as well. For details, you can add Qq197925618

This belongs to the category of structured packing; it is likely more advanced than packing rings. The product is pre-processed for use in tower equipment, and it can be assembled directly upon installation. It is more convenient during construction, offers a more uniform reduction in resistance, and has a larger specific surface area; in fact, it is better than loose packing rings.

Excessive resistance may be due to special operating conditions or an inappropriate selection of structured packing

It’s not that the filler is outdated; it’s just being used in the wrong place. If the material tends to cause clogging, could the use of trays be considered?

The regular packing you mentioned is the one in my picture, right? Where is it mainly used?

Tray – what is this? Could you show it?

Structured packing differs from random packing in that, in order to increase the residence time and improve reaction efficiency, packing rings are installed inside the tower. However, these packing rings are individual components, and during installation they are usually poured in and then spread out manually; as a result, the local resistance is uneven, and both installation and replacement are rather complicated. Later, structured packing was developed; these packing pieces are manufactured in advance by the manufacturer according to the inner diameter of the packing area in the tower, and can be assembled simply by stacking them together like building blocks. Such structured packing is uniform in all directions, has consistent pressure drop, and is easy to install and remove. Basically, wherever bulk packing could be used before, structured packing can be used in its place.
