以前我们有过三级克劳斯+氨法脱硫的设计，你的腐蚀具体在哪？烟气塔么？
脱硫塔，循环槽都有腐蚀，但是脱硫塔溢流管线焊缝处腐蚀比较厉害，修补多次，甚至大面积更换塔体材料都没能解决问题所在
脱硫塔，循环槽都有腐蚀，但脱硫塔腐蚀较为严重，开车半年时间，脱硫塔溢流管线腐蚀自已经有7次了，而且塔体材料都大面积更换了，但是问题还是没有解决
不好说，尾气里边肯定是没氯离子的，水里有，但都是经过计算的，按理是不会有，而且腐蚀老是这一个地方有点说不通，厂家说是电化学腐蚀，但采取了相应措施还是没有解决问题

如果资金允许，可以考虑从材料方面技改，防止电化学腐蚀，比如试用镀锌材料等。
溶液的PH值和硫铵副盐是多少？
建议检测下溶液PH值，也可能存在冲刷腐蚀；正常材质应选双相钢，306L不适合。
