An uncoated steel (assumed to be iron for simplicity) pipeline is proposed for the transfer of a deaerated weak acidic solution. Define the anodic and cathodic reactions. Calculate the equilibrium potentials of the anodic and cathodic processes. Calculate the corrosion potential (Ecorr), corrosion current density (corr) and the protection current density (prot) needed to stop corrosion for iron (Fe) in a deaerated corrosive medium. [Fe2+] = 10-3 M; pH = 2.5; ac = -0.380 V vs. SHE; ba = 0.120 V dec; bc -0.120 V dec; j = 1.5 10- A cm [Mark 50%] Construct an E vs. j plot (Evans diagram) using the calculated corrosion parameters. [Mark 30%] What assumptions are required when evaluating the corrosion parameters? [Mark 10%] What corrosion mitigation strategies could be implemented to protect the uncoated steel pipeline?
