Practice of technical transformation for ultra-low emission SO2 from flue gas of sulphur recovery unit
A certain refining and chemical enterprise has taken corresponding measures to carry out technical transformation in response to the problems existing in the sulphur recovery unit,and has achieved significant results.After the renovation,the anti-interference and fluctuation ability of the 1#sulphur recovery unit has been significantly improved.The concentration of SO2 emissions in the flue gas of the 1#and 2#sulphur recovery units has been significantly reduced,during the shutdown period,the concentration of SO2 emissions in the flue gas of the 1#sulphur recovery unit has been decreased from 4.41-52.55 mg/m3 to 1.59-12.77 mg/m3 and the concentration of SO2 emissions in the flue gas of the 2#sulphur recovery unit is close to 0,achieving long-term green,environmentally friendly,efficient,and stable operation of the unit.
