Abstract: The kinetic model for desulfurization using CaO-based powder injection has been proposed,which accords with the actual process of the experiment. For the model, a comparison between CaO-based flux and Mg-based flux was made and the results show that the desulfurization rate of the Mg-based flux is far more than that of CaO-based flux. On the basis of the model calculation,on comparison of CaO-CaF2 flux and calcium aluminate flux, the desulfurization rates of the two fluxes are close to each other. In addition, the effects of some operational factors on the kinetics of desulfurization are discussed.
