摘要:针对湿法同时脱硫脱硝工艺 ,提出通过构造一个液相反应过程 ,将 NOx 和 SO2 溶解在溶液中生成的 NO2 -2 和 SO2 -3 经过一系列连续的液相离子反应生成有利用价值的 NH+4 ,实现资源的合理利用。在 35°C~ 74°C,离子强度为 0 .5 5 mol/L时对羟胺二磺酸钾磺化反应动力学进行了研究 ,得出反应的动力学方程为 :- dcHIDSdt =kc HON( SO3) 2 -2 · c HSO-3,其中 k=5 .5 0 9× 1 0 8· e-6.154× 10 4 / RT;在5 0°C、离子强度为 0 .31 mol/L~ 0 .65 mol/L时 ,研究了该反应的盐效应 ,结果表明该反应呈负盐效应 ,离子强度为零时 ,有最大的速率常数 k0 =0 .0 2 4 7L /( mol· min)
To make use of the SO 2 and NO x in flue gas, a liq uid ionic reaction process is put forward to turn SO 2 and NO x into the v aluable (NH 4) 2SO 4 for the process of the simultaneous absorption of SO 2 and NO x . This process consists of five successive ionic reactions, includi ng the reaction between nitrite and bisulfite, the sulphonation of hydroxyimidod isulfate, the hydrolysis of nitridotrisulfonate, the hydrolysis of imidodisulfa te and the hydrolysis of sulfamate. The sulphonation of potassium hydroxyimidodi sulfate to potassium nitridotrisulfonate has been investigated. The reaction kin etics exhibits first order dependence on bisulfite and hydroxyimidodisulfate re spectively. The sulphonation reaction kinetic equation can be expressed as -d c HIDS d t = kc HON(SO 3) 2- 2 · c HSO - 3 , where k =5.509×10 8·e -6.154×10 4/ RT L/(mol·min) at I = 0.55mol/L in the temperature of 35°C ~ 74°C . The dependence o f t he rate constant k on ionic strength is also investigated. Negative salt eff ect was exhibited in the range of 0.31mol/L^0.65mol/L.
