| 摘 要： | 根据化学反应的热力学原理,分别计算了过硫酸钠溶液脱硫脱硝时的摩尔反应吉布斯自由能变,摩尔反应焓变,化学反应平衡常数,以及吸收平衡时SO_2和NO的分压,从而分析了反应进行的方向和限度。结果表明采用过硫酸钠溶液吸收烟气中SO_2和NO是可行的。

| Abstract: | During simultaneous desulfurization and denitrification by Na2S2O8 solution, molar reaction enthalpy, molar formation Gibbs function, partial pressure of SO2and NO and constant of reaction rate were respectively calculated based on the principle of chemical thermodynamics. In addition, limit and orientation of the reaction were analyzed. The results show that simultaneous desulfurization and denitrification by sodium persulfate solution are available. |
