What is Sulfide Stress Cracking?blueskyadmin
Sulfide stress cracking, sometimes referred to as SSC, is a type of embrittlement that occurs as a result of the presence of hydrogen sulfide. Certain alloys that are highly susceptible, including steels, may react to the presence of hydrogen sulfide and form atomic hydrogen and other forms of corrosion byproducts. SSC can be particularly problematic in the oil and gas industry since the materials that are produced within this industry frequently contain significant amounts of hydrogen sulfide.
While this situation can be quite problematic, fortunately there are methods for handling sulfide stress cracking. One of those methods is to implement H2S removal methods that will help in reducing the level of hydrogen sulfide to at or below accepted levels.
H2S removal can be accomplished in a variety of methods, based on the type of carrying fluid involved. When hydrogen sulfide is present in production fluids, it is typically removed through the use of H2S scavenging. A reaction with iron oxide method may be necessary in order to remove hydrogen sulfide when it is present in fuel.
