Supercritical Water Oxidation (SCWO) employs water which exceeds supercritical conditions (374℃ at 22MPa). This method utilizes the strong reactive solvent characteristics of supercritical water and can completely decompose organic materials in supercritical water. As a hazardous and refractory chemicals, decomposition of PCBs by SCWO was demonstrated using the continuous reactor with pressure balancing. This reactor has been successfully operated to decompose both PCBs and dioxins completely under the conditions of 630℃ and 23.5MPa.
