APPARATUS FOR THE INTEGRATED OXIDATION AND GASIFICATION OF AQUEOUS ORGANIC WASTE IN SUPERCRITICAL WATER

The invention pertains to the technical field of the treatment of organic waste and to the field of energy recovery from waste with a high concentration of organic material by oxidation and supercritical water gasification. The invention allows aqueous waste with a high concentration of organic material to be purified in an oxidation reactor, and part of the heat generated by strongly exothermic reactions is transferred through the wall of the reactor to an outer casing in which another aqueous stream of organic waste under high-pressure is circulated and heated until endothermic gasification reactions are produced to generate fuel gases (mainly hydrogen). The reactor and the casing thereof form a device similar to a heat exchanger with concentric tubes in which the heating fluid is separate from the cooling fluid.
