Abstract: The renovation to the abandoned and/or old oil tank and the optimal scenario to control internal corrosion of oil tank are discussed through analyzing the corrosion area of metallic oil tank and corrosion mechanics. In the article, corrosion control and renewal of oil tank as well as the process and advantages of renewal technology are introduced in detail. With less capital costs in renovation, this technology can bring the abandoned or old oil tank into operation. It is considered that this technology overrides other repair methods of abandoned or old oil tank.
