| Abstract: | Operation of three sulphur recovery units of the second Refinery Department, Jinling Petrochemical Corporation is introduced. Main factors influencing emission concentration of SO2 in tail gas were analyzed emphatically, including complex sources of raw gas, greatly fluctuating gas flow, high sulphur content in fuels, defects of air distribution control and solvent absorption systems. According to influencing factors, technical renovation measures and suggestions on lowering SO2 emission were put forwards. At present, SO2 content in flue gas from 3# plant was reduced to less than 280 mg/m3, meeting the new standard of environment protection. |
