  • In the turbulent contact absorber, the comparative study was carried on enhancement limestone WFGD with adipic acid and sodium adipate, the strengthenment effect and the buffering effect of two additives were investigated in the desulfurization process, the utilization rate of CaCO3 was analyzed and calculated by experiments. The results show that adipic acid and sodium adipate strengthenment experiments can get a higher rate of desulfurization in the lower pH, and two additives can promote greatly the dissolution of CaCO3. The desulfurization rate of sodium adipate is better than adipic acid’s under the same conditions, but the buffering effect of adipic acid is better than sodium adipate’s, and adipic acid has more remarkable effect than sodium adipate adipic acid with dissolution of CaCO3.

Abstract: In the turbulent contact absorber, the comparative study was carried on enhancement limestone WFGD with adipic acid and sodium adipate, the strengthenment effect and the buffering effect of two additives were investigated in the desulfurization process, the utilization rate of CaCO3 was analyzed and calculated by experiments. The results show that adipic acid and sodium adipate strengthenment experiments can get a higher rate of desulfurization in the lower pH, and two additives can promote greatly the dissolution of CaCO3. The desulfurization rate of sodium adipate is better than adipic acid’s under the same conditions, but the buffering effect of adipic acid is better than sodium adipate’s, and adipic acid has more remarkable effect than sodium adipate adipic acid with dissolution of CaCO3.
