|Title:||Hydrogen Damage Analysis In Catalytical Cracking Units Steels Of Petroleum Refineries By Scanning Electron Microscopy|
|Abstract:||Corrosion of vessels and piping made of steel by sour water in catalytical cracking units of petroleum refineries generate atomic hydrogen. Large part of this hydrogen will go to the atmosphere as H2, a fraction will diffuse in the steel lattice and stay in the defects, while the balance will diffuse through the lattice. The most well known effect in these steels is blistering and cracking induced by the retained fraction of hydrogen. In this work scanning electron microscopy was used to identify the damage caused by hydrogen and the damage susceptibility of two steels commonly used in catalytical cracking vessels.|
