Are structured packing materials useful?
Thread Content
Everyone, have you used magnetic structured packing in your dry scrubbers? How is the performance? Are there any damages? By how much has the resistance decreased compared to before? Fetch the scriptures
The structured packing has been tested by manufacturers for use in drying towers, but with little noticeable effect. For absorption towers, since a considerable proportion of the material is condensed into acid, I believe it is unnecessary to use structured packing; even if it is used, the effect will be minimal.
Recommended manufacturers of dry scrubber packing: stepped rings can be stacked neatly, which reduces resistance slightly; however, the effect is not very significant
The regular filler we use also works quite well
For the first and second stages of absorption, structured packing can significantly reduce the pressure drop in the tower; in some older systems, it can also increase production, as the basic height required for heterocyclic saddles is 7 meters, whereas with structured packing 4.5 meters is sufficient. You can specifically consult several factories in Pingxiang, Jiangxi. The technical documentation is extremely detailed.
The structured packing used in Sulfuric Acid systems at Sichuan Chemical Group is said to work well! This post was last edited by Peach blossoms are in bloom on 2009-2-19 12:02.]
There are also ones with an off saddle ring packing height of 2.6 meters.
Overall, it seems that structured packing still has its advantages. It’s a bit more expensive and cannot be cleaned. However, there is still much potential for reducing pressure drops and increasing the output of the original system. The manufacturers in Pingxiang can be asked to provide comparative parameters.
