| Abstract: | To improve desulfurization efficiency of limestone in the wet flue gas desulfiarization （WFGD）, effect of the surfactant sodium dodecyl sulfate （SDS） / dodecyl sulfobetaine （DSB） composite additive on limestone desulfurization agent were studied with self-made micro-simulation spraying type FGD apparatus. The results show that ： optimum additive composition ： SDS/DSB3 ： 2＋Na2SO4 （0.01 mol/L） . When the new composite additive is up to 10 mmol/L, solubility of limestone is the highest, it increases about 9 times than those without additive; desulfurization efficiency increases by 5% and up to 93%; it buffers the slurry pH well. The experiment has practical value on industrial application of WFGD. |
