变换气冷却塔腐蚀原因分析及改进

FAILURE ANALYSIS OF SHIFT GAS COOLING COLUMN AND ITS IMPROVEMENT

分析变换气冷却塔失效原因 ,认为主要是电偶腐蚀造成的。更新时将塔体材质改为 16MnR +0Cr18Ni10Ti复合板 ,设备内部腐蚀甚微 。

This paper analyzes the failure reasons of the shift gas cooling column.It's believed that the main cause is the galvanic corrosion.After changing the material to 16MnR+0Cr18Ni10Ti clad,there's almost no inner corrosion in the equipment which proves that the new material is feasible.
