I would like to ask the experts in the chemical industry and those working in petrochemicals: how to deal with rust on the walls of stabilizer towers
Thread Content
Dear experts, I have a question: we have a gasoline stabilizer tower, and there is something similar to rust on the walls of the tower. Please help us analyze what could be causing this issue. The temperature inside the stabilizer tower is 145°C, the top pressure is 0.45 MPa, and the top temperature is around 50°C. There is also a diesel preheating heat exchanger at the bottom of the tower
This is normal inside the tower; it’s caused by corrosion! How long has it been running?
Corrosive oxidation is normal and is related to the sulfur content of your raw material
Sulfur in gasoline causes corrosion; otherwise, there would be no need for subsequent gasoline refining systems!
It is normal for corrosion to occur due to high temperatures, oxidation, and a high sulfur content in the raw materials
Is this the situation right after the shutdown for maintenance? It seems like oxidation and corrosion have occurred over time due to its being out of use
It has been 7 months since the last maintenance – is this also sulfur corrosion?
Well, it was scheduled for maintenance after 7 months of normal operation; was it discovered after starting the tower agitator? I feel it’s a bit like the effect of high temperatures
Is this normal? Will it affect driving?
This is mainly a naphtha stripping tower; it shouldn’t be the problem behind that, right? Could it be related to temperature, medium, and sulfur content?
