Is anti-corrosion treatment needed for the inner wall of the chimney?
Thread Content
For sulfur-containing process units, it is understandable; in the case of methanol deep-processing units where there is no sulfur, what is emitted from the chimneys is mainly carbon dioxide. Is anti-corrosion treatment necessary?
As far as is known, the interior of sulfur-containing steel chimneys also lacks anti-corrosion protection; this is why it is required that the exhaust temperature not be lower than the dew point temperature.
What I read is that the flue gas contains water due to the installation of a wet dust collector
You are referring to dust removal; dew point corrosion is not simply a matter of steam forming water droplets, but rather a problem in which a large amount of sulfur dioxide gets dissolved in those tiny water droplets.
It is recommended to do this in order to prevent corrosion inside the chimney and extend its lifespan~~
What material is the chimney made of? Steel chimney? Still a concrete structure?
It is necessary to take into account factors such as exhaust gas temperature and the properties of the flue gas
It would be best to carry out anti-corrosion treatment on the inner wall if conditions permit. Also, what is the structure of the chimney – concrete or steel? Different structures require different materials, and I have worked on many such projects! I hope to discuss learning with you and make progress together
