ABSTRACT:
A process for disposing of a waste chemical stream containing materials which can produce objectionable combustion products, such as NO.sub.x, free bromine, carbon, particulates or ash, the process comprising the steps of passing the waste chemical stream to an oxidizing first zone where burning occurs in stoichiometric oxygen excess above about 2000.degree. F.; then to a reducing second zone where reaction occurs in stoichiometric reduction at a temperature of above about 2000.degree. F.; and then to an oxidizing third zone to oxidize the combustibles at temperatures of between about 1400.degree. F. and 2000.degree. F. The process provides high efficiency destruction of waste compounds, whether solid, liquid or gaseous, in a substantially NO.sub.x free manner. In the case of brominated compounds, the process generates HBr which is readily scrubbed.
