摘　　要：原油的重质化和高含硫特性对炼油装置的腐蚀日趋严重,影响了装置的长周期运行。文中分析了常减压蒸馏装置的腐蚀原因,并针对低温和高温2种腐蚀环境,提出了设备、管道材质选用和相关的防护措施。The corrosion to oil refining equipment is on the rise due to the crude oil becoming heavier and containing high sulfur content,which affected long-period operation of the unit. This paper analyzed the causes for corrosion in Atmospheric and Vacuum Distillation Unit,and proposed selection and relevant protective measures of equipment and pipeline materials for low-temperature and high-temperature corrosion environments.
