ABSTRACT

In order to control the corrosion in pipelines, it is important to understand the underlying corrosion mechanisms and prediction of it's initiation and means of mitigation. This paper reviews the electrochemistry of corrosion, it's kinetics and thermodynamic nature, with respect to CO2 and H2S effects in propagating corrosion in oil and gas pipeline system. The phenomenon of polarization and it's importance in the mitigation of corrosion processes was highlighted in relation to it's mechanisms. Several principles and models used in predicting and evaluating corrosion kinetics were reviewed emphasizing their applicability in the oil and gas pipeline system. Scale formation on metal surface plays a prominent role in the rate of corrosion propagation making the process more complex, hence the mathematical models to extract the parameters which determine the effect of scale formation were appraised.
