Clogging of the packing in the exhaust gas absorption tower
Thread Content
During the process of replacing the liquid in the absorption tower, the packing became clogged. The absorption tower originally contained 20% NaOH; after draining it, water was used for replacement, and then clogging occurred. I would like to know why this happened
If a sodium hydroxide solution is sprayed for an extended period, it will deteriorate and produce a large amount of sodium carbonate, resulting in a decrease in its solubility
There are too many impurities in the water, such as calcium and magnesium ions, which cause blockages.
