Abstract:
The paper introduced a perfect ly mixed flow mathematics model of wet f lue gas desulfurization (WFGD) for a pilot-scale jet bubbling reactor ( JBR) , including the absorption model of SO2 in lime slurry and a JBR reactor model. Prof iles of different special concentration and pH value in JBR w ere predicted by equat ions of the model. The absorpt ion rate of SO2, gasliquild phase mass-t ransfer coeff icient s and effect ive specific interfacial area are calculated w ith the model. The model w as test ified in the process of lime WFGD. T he results show that the conclusions predicted by the model are in good agreement w ith the ex periments.
