Application of structured packing in low-temperature heat recovery towers
Thread Content
Many years ago, I helped a client resolve an issue related to the primary packing (structured packing) in a low-temperature heat recovery tower. Generally speaking, structured packing can be used without problems when the height of the main packing layer is 4–5 meters; its acid-repartitioning effect is weaker than that of randomly piled packing. Low-temperature heat recovery uses two-stage packing, with the packing height being limited. For manufacturers of packing materials that have successful applications in this area, it is recommended that they post in the comments below images of the low-temperature heat recovery towers they use, along with screenshots of the payments for the remaining balance and warranty deposit related to the supply of structured packing materials; this would be an excellent form of promotion^_^

The same incentives apply to those who apply on their own.
Teacher in an instant: For low-temperature waste heat recovery, if there are two layers of spray nozzles in the new tower, I don’t think it’s necessary to use structured packing. In the case of upgrading an existing plant, the original single absorption tower can be used as a secondary spray tower, with a primary spray tower installed at the front. The packing layer in the primary spray tower should be taller, and structured packing can be used there; of course, structured packing can also be used in the single absorption tower at the back as well. That’s my personal opinion{:9001:}
