TY - JOUR ID - TI - Evaluation of Corrosion Inhibitor Blend Efficiency in Recirculation Cooling Water of Al-Doura Refinery AU - Dr. Shatha A. Sameh AU - Eiman Ali Eh. Sheet PY - 2012 VL - 212 IS - 6th SP - 138 EP - 157 JO - Journal of Petroleum Research & Studies مجلة البحوث والدراسات النفطية SN - 22205381 27101096 AB - The corrosion behavior of carbon steel in circulating cooling water (C.T.) of Al Doura Refinery and performance of sodium nitrite (SN) and sodium hexametaphosphate (SHMP) inhibitor blend for inhibition of such corrosion process have been investigated at different temperatures, i.e., 303, 313, 323 K.Weight loss experiment, under isothermal conditions, together with polarization method were carried out at 303, 313, and 323K using C.T., and make up with SN:SHMP (500:100) solutions. The results proved that the inhibition efficiency of the corrosion inhibitor used in this work is better than that obtained by the corrosion inhibitor used in C.T. of Al Doura Refinery and less effected by the change in temperature.
