Electrochemical Studies of the Hydrogen Sulfide Corrosion Mechanism

Abstract

A statement of the anodic and cathodic reactions in the hydrogen sulfide corrosion process is given along with experimental evidence to indicate that these reactions are the important ones. The corrosion process is explained further in terms of the electrochemical properties of the corroding solution and the corrosion products. Results of laboratory experiments indicate that the description of the mechanism is correct. The possible usefulness of an understanding of the corrosion process is demonstrated by a few practical applications.
