钢质原油储罐的腐蚀与防护

随着石油石化行业的快速发展,对原油的储存提出了更高的要求,这就需要新建大量的原油储罐。基于原油的理化性质相对复杂又具有极强的腐蚀性,因此,研究原油储罐防腐蚀的举措和方法受到高度的重视。针对原油储罐的腐蚀现状,为确保大型储罐安全长周期运行,解决储罐防腐技术应用中的腐蚀泄露问题,降低储罐的事故风险,分析了针对储罐各个部位的腐蚀机理所采取的防腐蚀措施。最后阐述了影响储罐防腐蚀效果的原因。

Corrosion and Protection of Steel Crude Oil Tanks

With the continuous development of petroleum and petrochemical industry, and increasing of oil storage capacity, more and more storage tanks are being applied. Because the physical and chemical properties of crude oil are relatively complex and crude oil has strong corrosive, research on oil tank anti-corrosion measures and methods is very important. In this paper, based on the status of the corrosion of crude oil tank, in order to improve the service life of the tank and reduce the incidence of the tank, the corrosion mechanism of each part of the tank was researched. At the same time, the concrete corrosion protection measures were put forward. Finally, key causes to affect the tank anti-corrosion effect were analyzed.
