NaClO_2/氨水溶液同时脱除SO_2和NO的热力学研究

Thermodynamic study of NaClO_2/ammonia solution simultaneous removal of SO_2 and NO

利用化学热力学基本原理分别对NaClO2/氨水溶液同时脱除SO2、NO的反应过程中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化学反应达到平衡时的SO2和NO的分压力进行了计算,结果表明:利用NaClO2/氨水溶液同时脱除SO2、NO是可行的,且SO2和NO的脱除效率几乎可以达到100%。

Molar reaction Gibbs function change,molar reaction enthalpy change,equilibrium constant and the equilibrium partial pressure of SO2 and NO for the reaction of simultaneous removal of SO2 and NO by using aqueous NaClO2/ammonia solution were calculated based on the principle of chemical thermodynamics.As can be seen from the results,simultaneous removal of SO2 and NO by using NaClO2/ ammonia solution is available,and the removal efficiencies are nearly 100%.
