摘　　要：分析了甲醇回收系统的腐蚀原因,分析结果表明,甲醇回收系统的腐蚀是电化学腐蚀,既存在析氢腐蚀也存在吸氧腐蚀,同时还存在机械磨损,分析结果有助于在工艺上采取减轻设备腐蚀方法的选择。The causes of corrosion for The result mechanical showed that the corrosion methanol recovery system in MTBE plant have been analyzed. was caused by hydrogen-evolved and oxygen-absorbed as well as abrasion. This is a great help to take some countermeasures.
