Modeling of ammonia-based wet flue gas desulfurization in the spray scrubber
Yong Jia,Qin Zhong,Xuyou Fan,Qianqiao Chen,Haibo Sun 한국화학공학회 2011 Korean Journal of Chemical Engineering Vol.28 No.4
A mathematical model of ammonia-based wet flue gas desulfurization process was developed based on the double film theory. The calculated results of the desulfurization system for two 220 t·h^−1 boilers per unit by this model were compared to that of corresponding measured data. It was found that the calculated results agree well with the measured data for the operating conditions of pH, liquid/gas ratio and SO_2 concentration. This model can provide predictions of the absorption performance of an ammonia-based wet flue gas desulfurization process and appears to be helpful for designing scrubbers for SO_2 absorption with ammonia absorbent.
