Sulfidation corrosion (also known as sulfidic corrosion) is a result of naturally occurring sulfur (S) compounds found in crude oil. Mechanism of High Temperature Corrosion by Model Naphthenic Acids Peng Jin, Winston Robbins, Gheorghe Bota Institute for Corrosion and Multiphase Technology, Ohio University 342 West State Street Athens, OH 45701 USA ABSTRACT Naphthenic acid (NAP) corrosion is one of the major concerns for corrosion engineers in refineries, Mechanism of high‐temperature sulphide corrosion of metals and alloys Prof. St. Mrowec Director of the Institute of Materials Science, Academy of Mining and Metallurgy, Al. A new corrosion mechanism, i.e., “active sulfide-to-oxide corrosion mechanism,” accounts for the rapid corrosion attack on low-alloy ferritic steels and lower-grade stainless steels resulting from the formation of iron chloride (FeCl 2) vapor and associated cycling reactions. Mechanisms of High Temperature Corrosion. 151-158. Subtitle: a kinetic approach. High Temperature Sulfidation (Sulfidic) Corrosion: causes,mechanisms and prevention. At first glance, this would therefore seem to be a very simple process but, in fact, it is considerably more complex.

WebCorr has NACE certified Corrosion Specialist (#5047) providing corrosion consultancy services, corrosion expert witness and corrosion short courses for in-house training, online and distance learning. Description: The oxidation of metals is, by definition, a reaction between a gas and a solid which usually produces a solid reaction product. The ability to handle air sensitive materials and couple that with corrosion characterization methods has led to the ability to identify corrosion degradation mechanisms and corrosion rates as well as evaluate mitigation methods. Mechanisms of High Temperature Corrosion - A Kinetic Approach Sarrazin , Pierre , Galerie , Alain , Fouletier , Jacques This book is an excellent summary of the basic principles of high temperature corrosion; an understanding of which is of paramount importance in understanding the subject. High temperature sulfidation is probably the most well-known corrosion mechanism in the oil refining industry because it occurs in large sections of the refinery. The high-temperature materials degradation facilities enable a high degree of control for testing novel systems. Book Cover. 35, Microscopy of Oxidation 10, pp. Corrosion fatigue testing: the combined effect of stress and high temperature corrosion. Fuel sometimes contains vanadium compounds or sulfates which, having a low melting point, can form compounds during combustion. (2018). Sometimes, this type of damage is called dry corrosion or scaling.The term oxidation is ambivalent because it can either refer to the formation of oxides or to the mechanism of oxidation of a metal (i.e., its change to a higher valence than the metallic state). High-temperature corrosion is a mechanism of corrosion that can take place in gas turbines, diesel engines, furnaces or other machinery coming in contact with hot gas containing certain contaminants.
