ORGANIC WASTE DETOXIFICATION METHOD Russian patent published in 2003 - IPC

FIELD: waste disposal. SUBSTANCE: invention relates to detoxification methods involving flameless combustion of liquid organic waste for use in chemical and petrochemical industries as well as in nuclear power area. Organic waste containing extraction mixtures, prior to be detoxified, is separated into extractant and diluent by introducing easily pyrolized displacement agent. Diluent is oxidized in lower section of double-zone reactor in fluidized catalyst bed at 700-750 C. Oxidation of extractant-displacement agent mixture as well as trapping of acidic gases by alkali adsorbent (calcium carbonate) is carried out in upper section of double-zone reactor in fluidized inert material bed at 700-750 C. The two oxidation processes are carried out alternately. Advantageously, easily pyrolized displacement agent is represented by carboxylic acids. Diluent oxidation heat is used to heat inert material bed. Alkali adsorbent is passed into fluidized catalyst bed. Emission gases, if necessary, are additionally freed of carbon monoxide and hydrocarbon traces on cellular catalyst at 450-500 C. EFFECT: reduced detoxification expenses and avoided formation of secondary pollutants. 8 cl, 1 dwg, 1 tbl
