摘要
分析了气体脱硫装置再生塔底重沸器腐蚀原因主要是CO2引起的,设备结构不合理和冲蚀也是重要原因。采取了重沸器形式改进、材质升级、溶剂净化和工艺条件优化等防腐蚀措施,取得了明显效果。
The causes of corrosion of the bottom reboiler of solvent regenerator in a gas desulfurization unit were analyzed. The carbon dioxide in the solvent, inappropriate equipment construction and erosion were the major factors resulting in corrosion. The corrosion prevention measures, including equipment construction retrofit, upgrading materials, solvent purification and process condition optimization were proposed. Good results have been obtained.
