| Abstract: | The influence and dosage of types of complexing agent and reducing agent on iron stabi-lizer were investigated and the optimum formulation of iron stabilizer was optimized and then the iron sta-bilizer was evaluated.The results showed that the iron stabilizer prepared with EDTA and citric acid as the complexing agent,n(EDTA)/n(citric acid)at 4.00,n(complexing agent)/n(iron)at 1.0-1.2 and ascorbic acid as the reducing agent with the addition amount of 2 g/L had better performance and good compatibility with other additives.Under the same desulfurization process conditions,after operation for 5 d,the complexing agent degradation rate of the self-made iron stabilizer was 5.0%,which was better thanCT 15-2,but slightly worse than ARI-350. |
