Abstract: The wet clean system for treating FCC regeneration flue gas in 2.5Mt/a FCCU of Sichuan Petrochemical Company was described. The system consists of EDV?5000 (Electro-DynamicVenturei) desulphurization and LoTOx (Low Temperature Oxidation) denitration process introduced from DuPont-Belco Corp. The application of the technology make the concentrations of pollutants in the flue gas reduce significantly. The concentration of SOx is reduced from 850.0mg/m3 to 5.0mg/m3, the nitrogen oxides is reduced from 205.0mg/m3 to 33.2mg/m3, and the catalyst particles is decreased from149.8mg/m3 to 24.3mg/m3. The quality of the treated flue gas is in consistence with the requirements of GB31570-2015 oil refining industrial pollutants emission standards.
