Management of Corrosion Damage Using Electrochemical Noise Monitoring and Future Approach

摘要

Corrosion damage in chemical plants equipment may occur not only in shut-down of plants, but in the worst case may lead to severe accidents which threaten the very existence of the plant. Corrosion in equipment was monitored continuously and causes of the corrosion was clarified, using the development electrochemical noise monitoring method, during a operation of chemical plants. This paper describes a method of plant management in which operating conditions are controlled in order to suppress corrosion, and also introduces principles of corrosion measurement. Topics related to corrosion management, and future performance in the field, are also explained.
