Abstract:
A detailed model of w et g as desulfurization(WFGD) for a pilot-scale w et ted-wall column has been developed. The model included an overall reactor model and four rate determining steps, i. e. absorpt ion of SO2, ox idat ion of HSO- 3 , dissolution of limestone, and crystallisation of gypsum. All important species in WFGD, SO2( g ) , SO2( aq) , HSO - 3 , SO 2- 3 , HSO- 4 , SO 2- 4 , CO2( g) , CO2( aq) ,HCO - 3 , CO 2- 3 , Ca 2+ , CaCO3( s) , Mg 2+ , O2( g) , O2( aq) , CASO4·2H2O( s) ,H2O, H+ and OH- w ere considered in the model. The modelling way mentioned here may be applicable to other w et FGD plant s.
