Review of Supercritical Water Oxidation in Hydrothermal Flames

Abstract:

Supercritical water oxidation in hydrothermal flames is a promising method for the total destruction of refractory compounds because it can overcome corrosion and salt deposition problems. In case of wastewater with a low reaction heat, the use of auxiliary fuels, to increase the reaction heat for the auto thermal operation is necessary. Methanol and isopropyl-alcohol were usually used as fuels. This paper compares the two fuels in hydrothermal flames and reviews the experimental results of salts, acetic acid, dioxins, ammonia, sludge and phenols of naphthalene and toluene. The results show that the destruction process obtains high TOC removals, and phenols are easy to cause soot formation problems. If soot deposition problems can be solved, supercritical water oxidation in hydrothermal flames will have a bright prospect for commercial applications.
