Corrosion Problem of Supercritical Water Oxidation Constructional Materials

Recently, a lot of work has been performed to put supercritical water processes to practical use. Especially, supercritical water oxidation (SCWO) is an efficient procedure for rapid and complete destruction of organic compounds. However, corrosion of the materials of fabrication is a serious concern. The current data base suggests that iron-base and nickel-base alloys are not likely to be capable of handling conditions associated with aggressive SCWO streams. Titanium alloys are recommended for severe SCWO service applications.
