Corrosion in petroleum products

What is it about?

The complex phenomenon of contamination is described in this paper in order to demonstrate its importance, as the number of failures of steel components is growing every year. It is important to understand that the corrosion process proceeds at the interface of different phases. Water, H2S, corrosion products, ions, phenols, organic acids, and other organic sulphur-, oxygen- and nitrogen-containing compounds dissolved in petroleum products are the contaminants that are responsible for the further destruction of the steel components.

Why is it important?

Before the corrosion of steel can be detected there takes place a process of contamination of the petroleum products which results in contamination of the steel, its corrosion and failure. The liquid medium can penetrate relatively far into the metal by adsorptive migration resulting in a complex mechanism that needs more and more research and understanding, as the contamination problem was given little attention in the past decades but is continuously creating more problems
