【 摘 要 】

References(13)Cited-By(4)To investigate the mechanism of SO2 absorption with the chemical reaction in the limestone-gypsum process, the effect of limestone concentration and particle size on the SO2 absorption rate in limestone slurry was studied by using a stirred tank reactor at a constant pH and high temperature (50°C). An absorption model with a reaction plane based on the film model was also proposed for an actual flue gas desulfurization (FGD) plant. For the SO2 absorption rate depending on the concentration and particle size of limestone powder, the experimental values agreed quite well with the results calculated with the absorption model, regarding the limestone dissolution rate within the liquid.
