| Abstract: | In Daqing,crude properties was constantly deterioration at late exploitation stage,and the join of oil additives declined the effect of desalting,which caused electric equipment and pipeline corrosion increasingly serious.High temperature parts of vacuum distillation unit and corrosion mechanism of low position in Daqing oil refining process was mainly introduced.Combined with the characteristics of device and its current corrosion,some anticorrosion measures for distillation unit in Daqing oil refining was elaborated. |

| Keywords: | atmospheric and vacuum distillation crude oil corrosion anticorrosion |
