Abstract

Corrosive processes studies of metal surfaces exposed to crude oil plays an important role in petrochemical industry, especially when directly associated with petroleum extraction ducts. In this context, the aim of our work is studies the electrochemical corrosion of petroleum / water / steel interfacial systems, evaluating the resistance to chemical attack of different materials used in the petrochemical industry against corrosive compounds, such as naphthenic acids, hydrogen sulfide, among others, in the presence or absence of corrosion inhibitors and/or metallic protection. For this purpose, different petroleum / water/steel interfacial systems will be prepared and posteriorly investigated by electrochemical techniques, mainly by Scanning Electrochemical Microscopy (SECM). To obtain information about types of corrosion and morphology of the corrosive attack in the steel by the action of the contact with petroleum, in order to clarify the corrosion mechanisms for, posteriorly, propose the application of adequate measures to protection and prevention of the corrosion in petroleum ducts.
