Abstract

1453659 Wet oxidation of organic matter using free radicals BARBER-COLMAN CO 16 Sept 1974 [24 Sept 1973] 40200/74 Heading C1C A process for wet oxidation of combustible matter in solution or dispersion by exposure to an oxygen-containing gas under elevated temperature and pressure for a time sufficient to substantially reduce the COD is improved by vigorous agitation with simultaneous introduction of the oxygen-containing gas into the area adjacent to the high agitation so as to produce fine increments of gas which are rapidly distributed and to effect rapid transport of free radicals generated by the oxidation reaction to other sites capable of oxidation of combustible organic matter before expiration of the life of the free radicals, thereby to catalyse the oxidation reaction to achieve a high rate of oxidation of combustible organic matter in the aqueous medium. A reactor suitable for carrying out the above process is described in detail. The process may be used with organic waste, e.g. slimes and sludges, such as sewage. Suitable temperatures are 400-480‹ F., and pressures of 50-200 p.s.i. above autogenous pressure may be used.
