Seeking assistance with online acid cleaning of air-cooled towers and water-cooled towers
Thread Content
Both air-cooled towers and water-cooled towers are packed towers. It is necessary to clean the packing, but since the major maintenance is scheduled for winter, it is very inconvenient to remove the packing for acid cleaning. Has anyone ever used online pickling, with good results? Please share the contact information of the partner. Thank you!
The so-called pickling process should be carried out only if it is feasible, based on the actual needs on site. Regarding air separation equipment, it is necessary to examine and determine the condition of scaling inside the towers; if acid cleaning is indeed required, its effects also need to be tested and evaluated. Additionally, these of your devices have developed scale; shouldn’t the other coolers be pickled as well? ? ? Furthermore, if the crystalline scaling reaches a level that requires pickling, should we consider replacing the \"Lassie ring\" packing? ? ?
Why is pickling necessary? Do Pall ring packing materials suffer from scaling? This is the first time I’ve heard that filling material requires pickling. Please advise, experts! Personally, I don’t think it’s necessary; the main thing is to check whether the water from the distributor is distributed evenly and whether there are any blockages that could cause uneven cooling
The fillers for air-cooled and water-cooled towers are not very expensive; why go to the trouble and cost of pickling when you can simply replace them?
We wash it; we wash it every year. But it wasn’t cleaned during the maintenance last year, and that’s why problems arose this year. As long as the pH value is controlled properly (check relevant information), there should be no issues; I use acid cleaning for all my coolers.
There’s no need to wash the filler; if water quality isn’t well controlled, it’s better to replace the filler directly. Using washing methods can lead to other problems; for example, it’s not certain whether the substance can be completely neutralized after washing, and if not, there remains a risk of corrosion, so it’s not advisable to try this approach
