Monitoring the Long-Term Compatibility of VCI and CP Associated Components

Overview

Main Objective

The project will research and identify technologies that can detect and quantify the interaction between Vapor Corrosion Inhibitors (VCI)- and Cathodic Protection (CP)-associated components. Additionally, the project will provide an in-depth understanding of the VCI technology's operating parameters—including delivery methods, coverage, dosages, monitoring, reinjection, and interaction with CP and associated components such as anodes.

Public Abstract

Corrosion induced integrity breaches of the breakout tank bottoms result in the release of hazardous liquids which can migrate into the biosphere if secondary containment is not functional or is compromised; leakage of the hazardous liquids into the biosphere could have an adverse effect on public health and safety. VCI technology is an alternative corrosion control tool to CP, and can be used as standalone or in combination with CP. This project will help operators understand the complex interaction between VCI and CP. Widespread usage of VCI technology will help the tank operators improve mitigation of soil-side corrosion, and thus improve safety plus reduce the AST operational life-cycle cost.

The major project outcome will be an in-depth understanding of the VCI technology's operating parameters such as delivery methods, coverage, dosages, monitoring, reinjection, and its interaction with the CP and associated components such as the anodes. Most importantly, the project will result in generation of knowledge and in-depth understanding of the VCI technology that operators can directly use in field implementation, and thereby, improve life-cycle performance of the aboveground storage tank (AST) bottoms.

Anticipated Results: The major project outcome will be an in-depth understanding of the VCI technology's operating parameters such as delivery methods, coverage, dosages, monitoring, reinjection, and its interaction with the CP and associated components such as the anodes. Most importantly, the project will result in generation of knowledge and in-depth understanding of the VCI technology that operators can directly use in field implementation, and thereby, improve life-cycle performance of the aboveground storage tank (AST) bottoms.

Potential Impact on Safety: Corrosion induced integrity breaches of the breakout tank bottoms result in the release of hazardous liquids which can migrate into the biosphere if secondary containment is not functional or is compromised; leakage of the hazardous liquids into the biosphere could have an adverse effect on public health and safety.
