In the Autumn 2024 edition of Tanks & Terminals magazine, MATCOR’s Ted Huck highlights an alternative to traditional corrosion prevention methods for aboveground storage tanks (ASTs): Vapour Corrosion Inhibitors (VCIs).
ASTs, especially those storing hazardous materials like hydrocarbons, are highly susceptible to corrosion on their steel tank bottoms. Typically built on sand or soil foundations with a concrete ring wall, these tanks are vulnerable to soil-side corrosion over time.
While cathodic protection (CP), often combined with a secondary containment liner, has been a standard solution to prevent leaks and environmental damage, it has limitations. VCIs are a newer technology that offers an additional layer of protection for external tank bottoms, addressing some of the challenges CP alone cannot solve.
To dive deeper into VCIs, its application methods, and how its performance is monitored, read the full Tanks & Terminals article.
