Abstract Wet limestone flue gas desulfurization is the most common method in controlling SO_2 emission.A single limestone particle was chosen as object.Based on film theory,a mass transfer model of alkaline solution desulfurization was found,and then matlab was used to simulate.Through theory analysis of SO_2 in gas phase mass transfer and diffuse to liquid phase,the dissolution and diffusion of limestone and reaction taking place in the liquid,a series of hypothetic conditions were brought forward and a mass transfer model was found.The model can deduce the velocity of mass transfer.The results showed that the conclusions predicted by the model were in good agreement with those by experiment and the coincidental degree is 97%.This can offer the theory reference for studying the mechanism of wet desulfurization.
