南美重质原油加工工艺防腐技术分析

Analysis of Anti-corrosion Technology in the Processing of South America Heavy Crude Oil

南美重质原油具有高硫、高酸、高盐以及高密度的特点,加工过程中易发生低温硫化氢、氯化氢的腐蚀和高温环烷酸腐蚀。采取"一脱三注"、材质升级以及定期防腐监测管理等必要措施,是加工南美重质原油过程中抑制和削减生产过程中的腐蚀危害,保证生产装置长周期安全平稳运行的重点工作。

the South American heavy crude oil with high sulfur,high acid,high salt and high density features,acid corrosion prone to low-temperature hydrogen sulfide,hydrogen chloride process and high temperature naphthenic.Taken ＂one removal and three note＂,upgrading materials,as well as regular corrosion monitoring management measures,is important for processing heavy crude oil in the process of South America,can inhibit and corrosion harm reduction in the production process,production equipment to ensure the safe and stable operation of long period.
