A powder-particle spouted bed (PPSB) is proposed for removal of SO2 from flue gas. Experimental results of a bench scale process show that, in addition to the known advantages in a semidry desulfurization process, a PPSB enables more efficient SO2 removal. However, quantitative investigation of the relationship between SO2 removal efficiency and the influential factors is still needed before a PPSB can be used in the flue gas desulfurization industry. In this paper, based on the analysis of chemical reaction and mass transfer between sorbent particles and flue gas, a method for analyzing the SO2 removal efficiencies in the semidry desulfurization process with a PPSB is proposed. The relations of SO2 removal efficiency to such parameters as stoichiometric ratio, approach to saturation temperature, and sorbent particle diameter are established. The desulfurization efficiency is numerically simulated by this method. Comparison of the calculated results with the experimental data shows that this method is of satisfactory reliability for prediction of SO2 removal efficiency in this new flue gas desulfurization process.
