炼油设备在高含硫原油环境中的腐蚀与对策

Corrosion of Refinery Equipment in Processing High-sulfur Crude and Countermeasures

对加工高硫原油的炼油厂蒸馏装置腐蚀案例进行机理分析、比较和归纳,针对蒸馏装置常见的几种腐蚀类型提出了在线监控、工艺防护、材料升级和防腐结构优化设计等防腐措施。

The corrosion mechanisms of crude distillation unit in the refinery processing high - sulfur crude are analyzed, compared and summarized. Effective corrosion protection measures like on -line detection, process prevention, material upgrading and corrosion prevention optimization, etc are proposed based upon the corrosion forms commonly found in crude distillation unit.
