常减压装置塔器腐蚀防护

Corrosion Protection of Tower in Atmospheric and Vacuum Distillation Unit

近些年来炼油厂在高酸原油方面的采购成本不断增加,而原油性质改变等问题直接导致了设备腐蚀速率加剧,导致常减压装置塔器的腐蚀防护工作逐渐成为业内人士普遍关注的焦点。基于此文章首先分析了常减压装置塔器腐蚀介质与常见部位,其次分析了常减压装置塔的腐蚀原理,最后介绍了常减压装置塔腐蚀防护的策略,以期能够为顺利开展防腐工艺提供思路与依据。

In recent years,the procurement cost of high-acid crude oil in refineries has been increasing,and the change of crude oil properties has directly led to the increase of equipment corrosion rate.The corrosion protection work of atmospheric and vacuum distillation unit tower has gradually become the focus of attention in the industry.Based on this,the article first analyzes the corrosion medium and common parts of the atmospheric and vacuum distillation unit tower,then analyzes the corrosion principle of the atmospheric and vacuum distillation unit tower,and finally introduces the corrosion protection strategy of the atmospheric and vacuum distillation unit tower,so as to provide ideas and basis for the smooth development of the anti-corrosion process.
