Research Progress on Corrosion of Supercritical Water Oxidation System

Supercritical water oxidation (SCWO) is a potential organic waste treatment technology developed in recent 30 years,which has significant advantages and broad application prospects compared with traditional treatment technologies.However,the corrosion of equipment during its operation has severely restricted its promotion and application.Research on corrosion mechanism and corrosion control of SCWO process has been conducted,and materials experiments have been performed so as to control the corrosion of SCWO equipment from material selection and structure optimization.In this paper,the research development about corrosion of SCWO system at home and abroad is summarized and related issues are discussed.
