Abstract:
To study the simultaneous removal of Sulfur Dioxide (SO 2 ) and Nitrogen Oxides (NO x ) from simulated flue gas by wet method, a bubbling device containing calcium hypochlorite (Ca(ClO) 2 ) solution was used in the experiments. In the first place, thermodynamic analysis was conducted to determine the depth of reaction process, and the reaction mechanism of desulfurization and denitration was proposed. After that, experimental results exhibited that SO 2 could be removed by Ca(ClO) 2 solution completely while the removal efficiency of NO x was 41.2%. Moreover, on the basis of high SO 2 removal efficiency, the effects of various factors on the removal efficiency of NO x , such as: the height of liquid layer, Ca(ClO) 2 concentration, reaction temperature, initial pH value, O 2 percent, SO 2 concentration, and additives were investigated, respectively. Finally, simultaneous removal of SO 2 and NO x under the optimized conditions were investigated, SO 2 removal efficiency of 100% and NO x removal efficiency of 85.9% were achieved. The analysis of reaction products indicated that the main anions in the liquid phase were and . © 2015 American Institute of Chemical Engineers Environ Prog, 34: 1586–1595, 2015
