Abstract
A method of processing the waste stream includes introducing the waste stream into the Fluid Catalytic Cracking Unit such that waste stream is processed within the regenerator unit or in CO boiler unit such that the waste stream and the regenerator flue gas are burned within the regenerator unit or the CO boiler unit. The waste stream contains NHand the NHis converted to the NOx and N. The fluid catalytic cracking unit may further include an assembly for converting NOx to N. Flue gas from the CO boiler unit containing NOx and Nis fed to the assembly to NOx to Nwithin the assembly. The assembly for converting NOx to Npreferably includes a selective catalytic reduction unit containing a catalyst, and wherein converting NOx to Nincludes reacting the NOx with the catalyst to produce Nand HO.
