Application of Corrosion Control Manual in Decompression and Maintenance of Atmospheric and Vacuum units
The atmospheric and vacuum pressure device is the first process of crude oil processing.Due to the complex corrosive medium contained in crude oil,the overall corrosion risk of the atmospheric and vacuum pressure device is higher,and the safety risk is larger.Based on the guidance content of corrosion control manual,corrosion inspection was carried out in the atmospheric and vacuum equipment of a petrochemical enterprise.The corrosion control manual system describes the process flow,material selection,corrosion mechanism,corrosion loop analysis and prevention and control strategy of the device,and predicts the corrosion-prone parts found during downtime maintenance and puts forward suggestions.
