| 摘 要： | 针对因气田污水中大量的Ca2+、Mg2+、Fe2+、HCO3-等离子及一定量的SO42-和溶解的CO2、H2S气体造成甲醇回收装置塔底水热交换器、原料水热交换器等管束内外表面结垢、管束腐蚀穿孔、管束与管板焊接密封面渗漏等问题,对新热交换器管束进行TH-901涂层防腐处理,对已发生渗漏的热交换器管束进行部分或全部更换时也采用TH-901涂层进行防腐处理,取得了较好的效果。

| Abstract: | Due to the problem that fouling of inside and outside surface,corrosion and leakage problem of tube and plate welding sealing surface,which is caused by influx of Ca2＋,Mg2＋,Fe2＋,HCO3-plasma Ni the gas field sewage and a certain amount of SO42-,dissolved CO2,H2S.On the new heat exchanger tube bundle for TH-901 coating anti-corrosion treatment,to have leakage in heat exchanger tube bundle for partial or total replacement is also used when a TH-901 coating for anti-corrosion treatment,and achieved good results. |
