摘　　要：针对以PDS(双核酞箐钴磺酸盐)为催化剂的焦炉煤气湿法脱硫工艺中产生的副盐,从脱硫反应机理入手分析了其产生的原因,从脱硫效率、运行成本及设备安全等方面讨论了副盐对湿法脱硫系统的影响,并从工艺控制、运行操作等方面提出了应对措施。The causes of byproduct salt generation in COG wet-desulphurizing processusing PDS (binuclear metallo phthalocyanine) as catalyst are analyzed from the mechanism ofwet-desulfurization reaction. The effect of byproduct salt on the wet-desulphurizing system isdiscussed from the aspects of desulphurizing efficiency, operation cost and equipment safety.Countermeasures are put forward from process control and running operation, etc.
