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