This paper reviews sulphidation behaviour of steel structures in the refinery industry. The data presented are related to two aspects of the corrosion. One aspect refers to external degradation of the structures due to formation of sulphide scales on the steel surface and metal losses; another is connected with internal degradation, i.e. changes of steel microstructure and formation of internal corrosion products. The so-called modified McConomy curves, and the Couper-Gorman curves used to predict corrosion rates of steels in hydrogen-free refinery streams, and hydrogen-containing environments are shown. Decreased stability of carbides in steel due to the presence of sulphur on the steel surface is considered, and a role of hydrogen in this process is outlined.
