摘要
探讨了柠檬酸钠法吸收和脱吸冶炼厂低浓度SO2 过程的机理。理论分析得出 ,原始吸收液应由NaH2 Ci和Na2 HCi组成 ,其pH =4.5。并得到中试试验的证实。
The mechanisms of low SO 2 concentration come from smelter absorption and de-absorption by sodium citric acid process are discussed. The theoretical analysis shows that original absorbing solution which pH is 4.5 should contain NaH 2Ci and Na 2HCi. The result is confirmed by middle test.
