常减压蒸馏装置阻垢剂进料管腐蚀研究

Study on Corrosion of Hinder Pharmaceutical of Dirt Tubes of the Atmospherie-vacuum Distillation Unit

通过对常减压蒸馏装置阻垢剂进料管的材质、性能、工作条件及腐蚀形貌、腐蚀产物的全面分析与研究,找出了使进料管管壁发生大面积腐蚀的腐蚀介质及其腐蚀原因,并提出了减少阻垢剂进料管环烷酸腐蚀的措施。

The extensive analysis and study of metallurgy, performance, operating conditions, corrosion forms, corrosion products hinder pharmaceutical of dirt tubes in the atmospheric-vacuum distillation unit have located the corrosion media and corrosion causes large scale corrosion of tube wall. Effective measures are recommended to control the naphthenic acid corrosion .
