Abstract :
SO2 of boiler flue gas can be absorbed by Pyrolusite to produce MnSO4. The experiments of removal of SO2 were carried out in the absorption tower of padding. The pH value of pulp is controlled by rhodochrosite. The results showed that the absorptivity of SO2 was above 95%, absorptivity of flue dust was above 90% and the by-product technical grade MnSO4 was produced. The technique is a new techrhodochrosite. The results showed that the absorptivity of SO2 wasnology on: removal SO2 of boiler flue gas; waste treatment.
