Storage Tank Corrosion Protection Using SMP VCI Technology

Corrosion Protection of Process Plant and Equipment is a critical task which requires synergistic combination of different corrosion control technologies. Volatile Corrosion Inhibitors (VCI’s) have been found highly useful in protection from corrosion for various process equipment during construction, testing, service & storage.

RUST-X VCI’s have an advantage of a multi-modal protection mechanism:

1.     Evaporating and combining with moisture \droplets and protecting in vapor phase

2.     Settling on to the metal surfaces and

forming a multi-molecular film that inhibits corrosion

3.     Dissolution in water and penetration into soil and concrete to reach the rebar and metal and protecting it from corrosion.

4.     Forming a mixture with soil/concrete and migrating towards metallic surfaces offering them protection

Due to multiple ways of protection, RUST-X VCI’s have been found to effective, beneficial and can be incorporated during the construction phases. These can also be used for protection and enhancing the service life if the provisions for incorporation/injection have not already been made.

The VCI inhibitor is so effective that it can increase service life of tanks by up to 10-15 years. This reduced corrosion rates also provide higher safety, lower risk of accidents, lower risk of accidental environmental releases, reduced maintenance costs and improved economics.
