本文主要对炼油厂冷循环水中总磷的异常情况进行了分析,并且查找其中的原因以及对解决办法进行了分析,并且提出在有机磷酸盐和锌盐作为循环水系统的缓蚀剂,其表面活性剂组合物含有介质泄露,会使水的表面张力降低,可以把已经沉积成膜的磷酸盐以及锌盐清洗下来,进而致使总磷数量异常。 This article mainly analyzes the anomalous situation of total phosphorus in the cold circulating water of the refinery, and looks for the reason and the solution to the problem, and proposes that the organic phosphate and the zinc salt act as the corrosion inhibitor for the circulating water system, the surface The active agent composition contains a medium leak that reduces the surface tension of the water, cleans the phosphates and zinc salts that have been deposited into the film, resulting in an abnormal amount of total phosphorus.
