摘　　要：连续重整装置芳烃抽提系统的腐蚀原因 ,主要是环丁砜降解物的腐蚀。采用DI-Ⅱ缓蚀剂在注入量为 30 0 μg/g时 ,可使缓蚀率达到 90 %以上。对于局部腐蚀严重部位 ,可选用 18-The corrosion of the aromatic extraction system of continuous catalytic reformer was that caused by degradation products. When inhibitor DI-II was injected at a dosage of 300 μg/g, the inhibition rate was over 90%. For the severe corrosion location, 18-8 stainless steel could be selected.
