Evaluating Efficacy of Volatile Corrosion Inhibitors versus Traditional Methods for Preservation of Industrial Equipment and Operational Spare Parts

摘要

Corrosion protection of industrial equipment and spare parts during mothballing and deep storage is an ongoing issue worldwide. Many factors must be considered when determining best practice for asset preservation; length of time, type of equipment, accessibility, preventative maintenance schedule, and environmental and storage conditions have the greatest influence, while other conditions may also need to be considered. Traditional preservation methods such as nitrogen blanketing, desiccation, or heavy, wax based surface applied coatings can be costly to implement and maintain, and can become even more costly if they fail. Replacement of equipment can result in millions of dollars in losses - both in replacement cost and facility downtime. Incorporation of volatile corrosion inhibitor (VCI) systems is an effective method to replace traditional preservation programs. These systems are often more cost effective to implement, have little to no maintenance cost, and have less failures in long term preservation programs. These VCI systems will be explored in both laboratory and real world settings, compared to traditional systems, and costs of each will be compared.
