Study The Corrosion Behavior of Carbon Steel in Presence Of CO2 Gas in Oil Pipe Lines

The current work is the study of corrosion behaveior of carbon steel, in naturally aerated (3.5%wt NaCl) solution. A rotating cylinder electrode (RCE) system was used to produce conditions of turbulent flow, polarization experiments were conducted at various temperature and various rotating speed at each temperature.Similar experiments were carried out using CO2 gas at (32 ml/sec) flow rate.Corresponding experiments by weight loss were carried out in (3.5%wt NaCl) solution with Kerosene + 10% V salt solution and Gas oil + 10% V salt solution at 328k and (0, 400) r.p.m.Similar experiments were carried out in kerosene + 10% V salt solution at (298, 308 and 318)K and rotating speed (0) r.p.m at each temperature.Other experiments were carried out in pure kerosene at temperature (298 and 318)K and speed (0) r.p.m. All experiments were carried out with and with out CO2 gas.The results indicate that the corrosion rate of carbon steel is increasing70% with CO2 gas
