Electrochemical Transient Behaviors of Tubular Steel in Buffered Acidic Solution Dissolved with Hydrogen Sulfide and Carbon Dioxide

Abstract:

In this work, the electrochemical transient behaviors of tubular steel API-P110 in buffered acidic NaCl solutions saturated with 50% H₂S and different content of CO₂ mixture gases, were investigated by single potential step chronoamperometry. Analysis of the results shows that fewer reactants take part in the reduction reaction when adding CO₂ content from 17% to 50% in 50% H₂S containing solution. Anions desorption process controls the reactant transferring process in metal-solution interface in the solution containing H₂S and CO₂. When at higher overpotential, anions desorption enhances and hydrogen absorption depresses with the increasing CO₂ content in H₂S/CO₂.
