Corrosion in the ammonia scrubber tower in low-temperature methanol washing
Thread Content
The ammonia washing tower used in low-temperature methanol washing suffers from severe internal corrosion; the material used is stainless steel. Please discuss the mechanism of this corrosion. Additionally, we can discuss the impacts that not using this ammonia washing tower would have on the system, as well as possible solutions
The corrosion of the 304L lining inside the cylinder is also particularly severe. What could be the reason?
Is it corrosion of the ammonia stripping tower or corrosion of the ammonia washing tower?:o
Corrosion is related to the acidity or alkalinity of the gases you use; it certainly won’t be good if those gases aren’t used, and if they’re not necessary, the design would have been altered accordingly.
If the ammonia washing tower isn’t in use, the level of low-methylamine is high, making it difficult to remove
Our ammonia stripping tower is severely corroded; we have already replaced it. No severe corrosion has been detected in the ammonia washing tower at present
It is recommended to give more consideration to the chloride ion factor
