蒸馏装置常压塔的腐蚀分析

Corrosion Analysis of Atmospheric Tower in Distillation Unit

在炼油化工生产过程中,由于介质腐蚀性较强,工作环境较恶劣,蒸馏装置极易发生腐蚀失效,甚至引起装置停工,从而造成重大经济损失。通过总结蒸馏装置常压塔的腐蚀调查情况,分析了该设备发生腐蚀的机理,并提出防腐措施,为装置的正常运行提供保障。

In petrochemical production process, corrosion failure is easily happened, even to unit shut- down for the strongly corrosive medium and the worse working condition, which will cause financial loss. In this article, corrosion mechanism of the unit was studied by summarizing the investigation about almospheric tower, and the anticorrosion measures were pointed. This can ensure the safe running of the unit.
