Corrosion Protection of Mothballed EquipmentAbstractExisting corrosion protection methods for mothballed equipment during long term (6 months – 10 years+) storage and shipment in unpredictable environmental and application conditions are not always effective. In addition to their limited protection offered these approaches tend to be cumbersome complicated labor intensive and therefore very expensive. This paper describes a system that allows replacement of the technology by using inhibitors in conjunction with nitrogen or a vacuum to achieve highly efficient corrosion protection of any metal part in different environments (vapor space and liquid). We will discuss new inhibitor formulations and protection principles that are recommended for rapid and sustained corrosion protection of internal metal surfaces of enclosures in industrial environments. These environments can contain acidic gasses and relative humidity up to 100%. The recommended solutions can increase the useful service life of equipment reduce time between failures and time to repair.Keywords: mothballing long term preservation environment corrosion dehumidification inhibitor protection efficiency service life storage transportation oil gas offshore.
