Soil-side corrosion of aboveground storage tank (AST) bottoms is a great challenge. ASTs usually include active cathodic protection (CP) systems to mitigate soil-side corrosion of the bottoms. CP systems could fail leading to unprotected tank bottoms, and sometime corrosion could occur even with active CP. A study was conducted to determine efficacy of the vapor corrosion inhibitor (VCI) technology in mitigating corrosion. VCIs were discovered to be effective in mitigating corrosion when recommended dosages are used, and could also be used in combination with impressed current CP systems. Overall, VCI technology was found to be a viable corrosion control measure.
