Abstract: On the basis of heterogeneous reaction on the interfaces between the gas and liquid films formed on the solid surface in a plasma flue gas desulfurization dry reactor,a wet type of reactor should be considered more reasonable.Simulation of the process in a wet reactor for flue gas desulfurization by corona discharges was provided.Through deriving the dependence of the desulfurization rate of flue gas,energy yield,mole energy consumption upon parameters of injected energy density,mass transfer efficiency factor and pH value of the liquid absorbents,it was found that under the conditions of given energy injection of corona discharges mole energy consumption could be remarkably decreased when pH value was appropriately adjusted and the inner surface of the wet plasma reactor was appropriately porous.The results were in agreement with previous experiments.Energy consumption could be reduced to an acceptable value.
