对比了低磷含量、高磷含量2种预膜剂在榆林炼油厂循环水系统中对碳钢的缓蚀性能的影响。结果表明：用低磷配方TS-52805A预膜的碳钢挂片在循环水中防腐蚀效果更好。将TS-52805A预膜运行方案应用于榆林某炼油厂循环冷却水系统,运行一个月后监测挂片的腐蚀速率为0.025 mm/a,连续运行半年中每个月碳钢的腐蚀率均为0.050 mm/a以下,不仅明显减缓了碳钢的腐蚀速率,而且符合了环保的标准。
對比瞭低燐含量、高燐含量2種預膜劑在榆林煉油廠循環水繫統中對碳鋼的緩蝕性能的影響。結果錶明：用低燐配方TS-52805A預膜的碳鋼掛片在循環水中防腐蝕效果更好。將TS-52805A預膜運行方案應用于榆林某煉油廠循環冷卻水繫統,運行一箇月後鑑測掛片的腐蝕速率為0.025 mm/a,連續運行半年中每箇月碳鋼的腐蝕率均為0.050 mm/a以下,不僅明顯減緩瞭碳鋼的腐蝕速率,而且符閤瞭環保的標準。

The effects of the two kinds of low phosphorus and high phosphorus Pre-film in Yulin Refinery circulating water system were compared. The results showed that the effect of corrosion pre-filmed by TS-52805 A was better. Applied TS-52805A prefilming agent to the circulating cooling water system of Yulin Refinery, after running a month, the corrosion rate of the coupon was 0. 025 mm/a, operated for six months, the carbon steel corrosion rate was less than 0. 050 mm/a per month. The result showed that it not only slowed down the corrosion rate of carbon steel, but also was in line with environmental standards.
