The Influence of Several Ions on Pitting Corrosion in Sedimentary Water of Oil Tank

Abstract:

Article Preview

Hysteretic loops were used to study the influence of several ions in sedimentary water of oil tank on local corrosion at the bottom of crude oil tank, which were measured by the electrochemical station CHI660. The results indicated that the pitting increased firstly and then decreased with the increasing of the concentrations of each ion. The most serious pitting corrosion occurred under the following condition: the concentration of Cl-, SO42-, HCO3-, Mg2+, Ca2+ were 10.0 g/L, 1.0 g/L, 0.75 g/L, 0.35 g/L, 0.2 g/L, respectively.
