The Potential of Using Zn<sub>0.6</sub>Ni<sub>0.4</sub>Fe<sub>2</sub>O<sub>4</sub> Nanoparticles as Corrosion Inhibitor for Carbon Steel in Oil Environment

Corrosion is one of the serious problems in oil and gas industry. So far, many inhibitors have been used to control or reduce corrosion. Nowadays, nano-materials have been employed as inhibitors as well due to their excellent properties such as high surface area, excellent inhibition efficiency, low cost, and minimum toxicity. In the current work, nano-ferrite materials have been used as inhibitors to reduce the corrosion of carbon steel in oil environment (crude oil obtained from Iraqi Majnoon oil field). The anti-corrosion properties of the nickel and zinc ferrite on carbon steel in Iraqi oil media have been evaluated. The nano materials of nickel Ferrities (NiFe2O4) zinc Ferrities (ZnFe2O4) and Zn-Ni doped Ferities (Zn0.6. Ni0.4Fe2O4) were selected as additive ferrites. It has been found that nano-nickel and zinc ferrites could act as an effective corrosion inhibitor for the metal carbon steel. An average reduction of about 38% in the corrosion rate has been achieved when using Zn-Ni doped Ferities (Zn0.6. Ni0.4Fe2O4) with the crude oil as a corrosive environment.
