The report gives results of an analysis of flue gas desulfurization by a turbulent contact absorber (TCA) employing lime slurry, including the development of performance equations for the scrubber-hold tank recycle system. Performance characteristics investigated include pressure drop of the scrubber, CO2 and SO2 absorptions, and lime utilization. Experimental data obtained from EPA/Research Triangle Park and TVA/Shawnee Power Station are used for the analysis and correlation. The analysis of CO2 absorption indicates that the overall mass transfer coefficient is a function of the pH of inlet and outlet scrubber liquor and is very sensitive to the liquor flow rate. (The rate of SO2 absorption in a TCA has been developed previously by McMichael et al., 1976.) The correlations developed are used to formulate a simulation procedure for predicting SO2 scrubbing efficiency as a function of pH of slurry and gas and liquor flow rates. The result of simulation indicates that, for a given lime feed rate and a fixed inlet and outlet SO2 concentration, a maximum flue gas flow rate exists which the scrubber can treat by the recycling slurry. An example is shown for the design of a TCA capable of desulfurizing flue gas from a 50-MW power station.
