Scaling of waste boiler tubes in the spent acid regeneration unit
Thread Content
In WSA units, due to the high content of metal ions in the waste acid, molten metal salts are formed at the waste boiler tubes, causing blockages in these tubes and resulting in poor heat exchange efficiency. . Help needed
It seems that there are still some issues with using this technology for the treatment of acid solutions and waste acid
Mainly, alkylated sulfuric acids are quite dirty. . When we went to Hui Lian for an inspection, their operation was excellent and very stable
This boiler is just a steam heat exchange boiler. .
Huizhou uses our technology. . .
Huizhou’s waste acid regeneration units do not have waste pots; if such pots did exist, blockages would likely occur. Has the composition of the waste acid been analyzed?
Since scaling is a common phenomenon, the key issue is whether there are appropriate measures to deal with it once it occurs and whether recovery can be achieved quickly; starting up and shutting down sulfuric acid plants is very troublesome.
The content of metal ions in its composition is relatively high. . Sodium ions, nickel ions
Currently, it’s shut down for disassembly and dust cleaning, which is very troublesome
What is the sodium ion level? From what device?
