The invention relates to a method for essentially complete oxidation of a concentrated liquor (33) containing oxidable organic matter, comprising the following steps performed unter substantial superatmospheric pressure. According to the invention: (a) a feed (12) of the concentrated liquor (33), preheated (30, 31) to a temperature higher than about 10 °C below the boiling point of water at said superatmospheric pressure, is oxidised (1) essentially completely at a temperature of at least 800 °C with a gas (13) containing at least 60 per cent by volume of oxygen resulting in a suspension (4) of hot gas and molten slag; (b) the molten slag is separated from the hot gas (5) and dissolved in water (15); and (c) the separated hot gas (5) is quenched (7) to a temperature below 250 °C with an aqueous liquid (8) and then withdrawn (23).

L'invention a trait à un procédé permettant d'oxyder, presque totalement, un liquide concentré (33) contenant des substances organiques oxydables. Les différentes étapes de ce procédé s'exécutent à une pression bien supérieure à celle de l'atmosphère et consistent, (a), à oxyder (1) presque totalement, à une température d'au moins 800 DEG C, une charge (12) constituée du liquide concentré (33), préchauffé (30, 31) à une température quelque peu supérieure à une température de consigne, elle même inférieure de 10 DEG C environ au point d'ébullition de l'eau à ladite pression supérieure à la pression atmosphérique, à l'aide d'un gaz (13) contenant au moins 60 % par volume d'oxygène, cette opération donnant une suspension (4) de gaz chaud et de scories en fusion, (b), à séparer ces scories du gaz chaud (5) et à les dissoudre dans de l'eau (15) et, (c), à refroidir (7) le gaz chaud (5) à une température inférieure à 250 DEG C à l'aide d'un liquide aqueux (8) et, enfin à le séparer du liquide de refroidissement (23).
