| Abstract: | Aiming at the problem of unqualified flue gas from circulating fluidized bed boiler in Yan′an Petrochemical Plant of Shaanxi Yanchang Petroleum （Group） Co Ltd， the flue gas was treated by the integrated process of selective catalytic reduction denitrification and semi-dry desulfurization and dust removal.The results showed that after using integrated process，the average mass concentrations of NOx， SO2 and particulate matter in total flue gas emitted were 16.87， 7.67 and 0.42 mg/m3 respectively， which could meet the pollutant discharge requirements in DB 61/1226—2018. |
