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.
