The Effect of the Partial Pressure of H₂S and CO₂ on the Permeation of Hydrogen in Carbon Steel by Using Pressure Buildup Techniques

There are concerns in the industry about using an electrochemical technique for actual hydrogen permeation measurements where charging current is not a field condition. The objective of this work is to use pressure buildup techniques to study the influence of H 2 S and CO 2 partial pressure on the relationship between hydrogen permeation and corrosion rate measured by different techniques. Sulfide films formed on carbon steel in a solution...
