Patent ID: 7988869

Claim:
A reactor for treating a nitrate containing organic waste in supercritical water in a reactor, comprising a body ( 2 ) closed by a lid, a casing located within the body for forming an enclosed supercritical reaction area ( 10 ) having a pressure of at least 221 bars and for forming a confinement area isolated by the casing from the reaction area, an inlet ( 48 ) for introducing the organic waste into the supercritical reaction area ( 10 ), an internal tube ( 15 ) disposed in the supercritical reaction area ( 10 ) coaxial with the longitudinal axis of the body for forming a ring shaped area between the internal tube and the casing and forming a central area within the body and said reactor further comprising: at least a first and second end with the second end ( 15 a ) spaced from the inlet ( 48 ); a location ( 46 ) for introducing an oxidant into the supercritical reaction area ( 10 ), at least one outlet for discharging oxidized organic waste out from the supercritical reaction area ( 10 ), with said organic waste to be treated in the supercritical reaction area following a path defined between its inlet and its outlet, characterized in that the location ( 46 ) for introducing the oxidant into the supercritical reaction area ( 10 ) is located in the vicinity of the second end ( 15 a ) of the internal tube ( 15 ) downstream from the inlet ( 48 ) and is spaced apart from the latter for establishing an anoxic area in which the organic waste is in anoxia confined to said central area between the inlet for the organic waste and the location for introducing the oxidant, a heat exchanger disposed in said confinement area to heat or to extract heat power from the reaction area and to provide control of thermal gradients along the reactor and a rotatable turbine disposed in the reaction area with said turbine having a central shaft extending through the central area coaxial to the casing and first and second rotatable blades parallel to an axis of the reactor with the first blades positioned in the central area formed by the internal tube and the second blades positioned in the ring shaped area to enable said organic waste to be stirred.
