摘要
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 NH3 and the NH3 is converted to the NOx and N2. The fluid catalytic cracking unit may further include an assembly for converting NOx to N2. Flue gas from the CO boiler unit containing NOx and N2 is fed to the assembly to NOx to N2 within the assembly. The assembly for converting NOx to N2 preferably includes a selective catalytic reduction unit containing a catalyst, and wherein converting NOx to N2 includes reacting the NOx with the catalyst to produce N2 and H2O.
