Zerion FVS

ZERION

ZERION FVS’S TWO FORMS OF PROTECTION

1. Vapor Corrosion Inhibitors (VCIs) to protect the interiors of “air space” voids and exposed metal surfaces on welded joints, in crevices, at coating holidays, etc.
2. Soluble Corrosion Inhibitors (SCIs) that mitigate corrosion from moisture accumulation or the ingress of water.
This combination penetrates gaps and interstices inside of enclosed voids to provide comprehensive coverage. This solution does not contain phosphates or harmful fillers and is readily compatible with most industrial water treatment processes.

PROBLEM

Corrosion of aboveground storage tanks, equipment while out of use during long periods of time, exposed steel surfaces, voids, enclosures and more.

SOLUTION

Zerust Zerion FVS is a versatile new corrosion inhibitor specifically designed to protect ferrous metals in aggressive corrosion environments where there is the possibility of the accumulation of water, moisture and/or water ingress. Zerion FVS provides unique dual action corrosion protection. This new dimension of effectiveness makes Zerion FVS the best in class in the market today.

PRODUCT PROPERTIES

  • Appearance: White crystalline powder
  • pH: > 8-10 for 1% solution
  • Odor: Slightly amine like Shelf life is 36 months
  • Store in a sealed container in a dry, ventilated warehouse at temperatures below
  • For tank SSB application, it 70oC (170oF) with out exposure to direct sunlight may be used independently or in conjunction with cathodic protection.

Aboveground Storage Tank (AST) Soil Side Bottoms (SSB)

Zerion FVS has been used in multiple tank soil side bottom installations and provides superior protection to exposed steel in vapor spaces and crevices under the tank bottoms – and also in situations when there is ingress of water into the tank foundation space. Zerion FVS can be diluted with water and injected into sand/soil base or introduced as a powder during tank construction or bottom plate refurbishment. Even for tanks with concrete pad foundations, Zerion FVS in slurry form can be introduced into the spaces between the plates and the concrete to provide corrosion protection. Zerust has also pioneered a VCI Ring system using Zerion FVS if there is no liquid injection. This VCI Ring system is recommended for all SSB installations.

PRODUCT USE

The ready-to-use mesh sleeves are primarily meant for dry VCI application where there is also a risk of water ingress. The vapor space protection volume is provided in the table below. For aggressive environments with 1 ppm or higher level of acidic gases, Zerion FVS should be used in combination with Zerion AutoFog™ B. In the event of water ingress/accumulation, Zerion FVS will dissolve out of the packaging and neutralize the threat up to the volume of water indicated in the usage table.
For use of Zerion FVS as a water-diluted solution for hydrostatic testing or for tank SSB protection, it is recommended you contact Zerust Oil & Gas for technical support and sizing recommendations.

BENEFITS

  • Easy-to-use and versatile system.
  • Corrosion protection for voids and interstices that are impossible to protect with other methods.
  • VCIs offer non-permanent corrosion protection at the molecular level that is safe and eco-friendly.
  • May be combined with simple monitoring procedures to ensure effectiveness of the solution.
  • Protection for tank bottom plates and welds with little to no surface preparation.
  • For tank SSB application, it may be used independently or in conjunction with cathodic protection.
  • Vapor action ensures uniform distribution within the tank bottom.
