In a petrochemical company,the atmospheric and vacuum pressure unit of 100%Russian oil refining has been running for only 7 months,and 10 corrosion leaks have occurred successively in the pipeline from the outlet of the heat exchanger to the top of the atmospheric tower.Through the analysis of corrosive medium,corrosion process,corrosion mechanism and process anticorrosion analysis of the tower top system,the causes of corrosion leakage are found from the aspects of corrosive medium content,process parameter control and material selection,and corresponding process anticorrosion suggestions are put forward to ensure the long cycle operation of the device.
