注缓蚀剂罐泄漏原因分析及预防措施

Analysis and Preventive Measures for Leakage of Corrosion Inhibitor Tank

腐蚀现象普遍存在于化工、石油、造纸等行业中,腐蚀会造成设备和管道“跑、冒、滴、漏”,严重时会发生着火、爆炸等事故。因此,研究与解决设备和材料的腐蚀问题,与企业安全生产、防止环境污染、保护人民的健康息息相关。简要介绍了应对腐蚀的措施,选取注缓蚀剂罐的腐蚀泄漏案例为研究对象,描述了注缓蚀剂罐的概况和腐蚀情况,从使用的缓蚀剂出发,分析了发生泄漏的原因。结果表明:1%(质量分数)的多元醇磷酸酯水溶液pH为2~3.5,呈较强的酸性,与碳钢材质的注缓蚀剂罐发生化学反应,导致罐体腐蚀穿孔。采取相应的防护措施后,注缓蚀剂罐运行正常,使用效果良好。

Corrosion is a common phenomenon in industries such as chemical,petroleum,and papermaking.Corrosion can cause equipment and pipelines to"running,emitting,dripping,leaking",and in severe cases,accidents such as fire and explosion can occur.Therefore,researching and solving the corrosion problem of equipment and materials is closely related to enterprise safety production,preventing environmental pollution,and protecting people's health.The measures to deal with corrosion were briefly introduced.The corrosion leakage case of the corrosion inhibitor tank was selected as the research object,and the overview and corrosion situation of the corrosion inhibitor tank were described.Starting from the corrosion inhibitor used,the reasons for the leakage were analyzed.The results showed that a 1%aqueous solution of polyol phosphate ester had a pH value of about 2~3.5 and exhibited strong acidity.It reacted chemically with a carbon steel corrosion inhibitor tank,causing corrosion and perforation of the tank.After taking corresponding protective measures,the corrosion inhibitor tank operated normally and had a good use effect.
