加工高酸原油常减压蒸馏装置腐蚀原因分析及防腐措施

Analysis of corrosion causes and anti-corrosion measures of atmospheric and vacuum distillation unit for processing high acid crude oil

高含酸原油具有高酸值、高密度、高金属含量、高碳残留量和高黏度的特点,造成在精炼操作,产品质量和设备腐蚀存在许多问题。为了确保装置的正常运转,必须做好高硫高含酸原油的防腐工作,并为炼油的二次装置提供合格原料。

High acid crude oil has the characteristics of high acid value,high density,high metal content,high carbon residue and high viscosity,which causes many problems in refining operation,product quality and equipment corrosion.In order to ensure the normal operation of the unit,the anti-corrosion work of high sulfur and high acid crude oil must be done well,and qualified raw materials must be provided for the secondary unit of oil refining.
