There are three known types of high temperature sulfidation present in the refining industry. Two of them have industry recognized methodologies for damage prediction, and they both manifest as general thinning morphologies. They are known as H2-free sulfidation and H2/H2S corrosion. The third type, although recognized as H2-free, low-sulfur corrosion, does not have an accepted chemical theory or a prediction tool, and it manifests as a localized thinning morphology. This third type of sulfidation is much less common and occurs in units and process conditions where little-to-no H2S would be expected to be present. This paper discusses the operating conditions in two known damage cases presented here and provides a viable chemical theory that could lead to the observed damage profile. In addition, an approach to mitigation of this attack is discussed.

High temperature sulfidation is one of the oldest damage mechanisms in the refining process such as crude distillation unit, vacuum distillation unit and hydroprocessing unit. Since corrosion proceeds to general corrosion and occurs in a high temperature environment, it is a type of corrosion that can lead to a large fire explosion when a leak occurs.
