Supercritical water oxidation operating conditions

With respect to dense phase fluids, supercritical water has been shown to be a very effective reaction medium for oxidation reactions [8, 9]. Despite extensive research efforts, however, corrosion and investment costs form major challenges in these processes because of the rather extreme operation conditions required (above 647 K and 22.1 MPa) [10]. StiU, several oxidation processes for waste water treatment in chemical industries are based on supercritical water technology (see, e.g., [11]).
