渤海湾某平台的多相混输海管通球过程中,在收球桶的猪笼内发现大量垢片,严重影响了海管的正常生产运营。对结垢物进行X射线衍射分析(XRD),分析结垢原因,排除了细菌和腐蚀导致结垢,通过复配优化防垢剂配方,采用化学滴定方法等进行防垢剂效果评价试验,制定行之有效的治理方案,取得了较好效果。
In the process of multiphase transport of a certain platform in the Bohai Gulf, a large amount of scale tablets were found in the pig cage of the barrel, which seriously affected the normal production and operation of the pipe. The X-ray diffraction analysis (XRD) of the scale materials was carried out to analyze the cause of scaling, and to exclude scaling caused by bacteria and corrosion. The anti-scaling agent effect evaluation test was carried out by compounding the optimized anti-scaling agent formulation and the chemical titration method Effective governance programs, and achieved good results.
