常减压蒸馏装置常顶换热器的腐蚀分析与防护建议

The Corrosion Analysis and Protection Suggestion of Atmospheric Tower Overhead Heat Exchanger in Atmospheric and Vacuum Distillation Unit

文章通过对长庆石化500万吨/年常减压蒸馏装置的常顶油气换热器的腐蚀状况分析,分析得出引起腐蚀的基本机理,以及比照现阶段的防腐蚀状况的运行现状,找出了一些现阶段防腐蚀工作存在的不足,并且因此提出了一些有关于常顶换热器防腐蚀的建议。

Based on the analysis of Changqing Petrochemical 5 million tons/year of crude distillation unit overhead gas heat exchanger corrosion, fundamental analysis of the corrosion mechanism, operation status and present stage of corrosion, finds out the present lack of some anti corrosion in the work, and thus put forward some about Chang the prevention of corrosion of heat exchanger suggestions.
