The Elementary Attributes and Denotations of the Corrosion in Petroleum Refining Event

Crude oil is a natural resource for the generations of energy, occurred based on the phenomenon of the natural environment that also composed with most of hydrocarbons and some of trace compounds which are having various properties including the corrosiveness. Anticipations of this research were the investigations of the spirit of the corrosion of seven different types of ferrous metals with respect to the two different types of crude oils in both quality and quantity. The chemical compositions of selected metals, the strength of leading corrosive compounds of both crude oils, corrosion rates of each metal with respect to both crude oils and the aspects of corrosion were tested and determined by the standard methodologies and instruments. The concluded results interpret that some of the metals are having corrosion protection ability while especially stainless steels were having relatively lower corrosion rates, higher compositions of corrosive compounds in Das Blend accordingly with the concentrations of such compounds, salts play a dominant role in the metallic corrosion basically at the room temperatures that the experiments were performed, formation of FeS, Fe2O3, corrosion cracks and some irregular distributions of cavities on the corroded metal surfaces under these processes and also some property changes of the surfaces of metals due to the corrosion.
