摘要
某石化公司拱顶储油罐,其罐顶因受潮湿海洋气候和内部不合格柴油产生的硫化氢和硫的化合物气相的共同影响,造成罐顶板减薄,强度降低,最终导致罐顶塌陷。文章分析了该罐顶腐蚀失效的原因,提出了减缓罐顶腐蚀的措施。
Because combining effects of the humid oceanic climate and the sulfureted hydrogen and gaseous sulfide produced from unqualified diesel oil in a dome roof tank, the dome plates was becoming thin and reducing its strength. At last, the dome collapsed. The reason for corrosive failure of the dome is analyzed in detail in this paper, and the measures to slow down the dome corrosion are put forward.
