Corrosion prevention in the high-temperature section of the vacuum tower
Thread Content
How does everyone address the corrosion issue in the high-temperature section of their pressure relief towers? Is it by injecting high-temperature corrosion inhibitors (and where is the injection point?) ) Or a material upgrade?
In the high-temperature section of the vacuum tower, what kind of oil are you processing? High acidity? For high-sulfur conditions, the materials used for the tower internals are upgraded to 316L or even higher-grade 317L. The towers are lined with 317L or 316L. High-temperature corrosion inhibitors are said to be effective, but they aren’t widely used. However, they can be useful if there is existing experience with their use. Still, I believe that for high-temperature areas, the material itself is what really matters
