Weak organic amines are commonly used in crude unit overhead systems to prevent acidic corrosion from chlorides and other acidic contaminants via a neutralization reaction. While using commodity amines, some refineries experience salt-induced fouling and corrosion issues, which may prompt them to move to non-salting, lower strength amines. TOTAL decided to test this approach to improve reliability for its overhead systems in crude units. This was done through partnership with an industry-leading water technology and process providera to use their proprietary amine-neutralizing technologyb. This technology is based on a set of principles surrounding the blending of a variety of targeted amine
