Abstract
An improved process for disposal of chemically bound nitrogen in industrial waste streams is provided wherein a effluent stream containing chemically bound nitrogen, such as ammonia stream, is contacted with an effective amount of oxygen containing gas and a stoichiometric excess of a hydrocarbon, based on the total amount of available oxygen, at a temperature greater than about 2000.degree. F. or less than 3000.degree. F., to provide a combustion effluent. The combustion effluent is thereafter contacted with an effective amount of a gaseous stream containing less oxygen than that which supports flame propagation at a temperature in the range of from about 1600.degree. F. to about 1800.degree. F., to substantially oxidize all combustibles present in the combustion effluent and provide an oxidation effluent substantially free of oxides of nitrogen (NO.sub.x) and combustibles. The oxidation effluent may be cooled in heat exchange equipment to recover energy, recycled to support the combustion and/or the oxidation of the combustibles, or vented to the atmosphere.
