Corrosion Product Transport Monitoring With Non-Contact Nephelometry

By Randy Turner, Marco Lendi, and Dr. Heinz Wagner

Monitoring corrosion product transport in steam and water cycles is essential to minimize corrosion. Iron corrosion products exist predominately as undissolved suspended particles therefore to measure the total iron a digestion must be performed. Currently there are no total iron analyzers available to continuously monitor total iron therefore surrogate methods such as nephelometry as well as particle monitors have been employed. This paper describes the results of research employing nephelometry to monitor corrosion product transport.
