Abstract
An experimental study has been performed of the desulfuration performance of a liquid-curtain type absorption tower, during which the influence of such parameters as flue-gas flow rate, circulating slurry quantity and pH value etc. on its desulfuration performance was studied. When the structure and operating parameters of the tower are properly chosen, the desulfuration efficiency can reach 95%. The authors have presented a method for calculating the mass transfer area of the tower and established for it a mass transfer model. It has been found that the mass transfer coefficient of the tower does not vary significantly when pH value is in a range from 5 to 10. In addition, an empirical correlation formula of the mass transfer coefficient of the tower concerning gas phase and liquid phase Reynolds Number has been obtained.
