Corrosion Control Manual Technology Guide Application to Corrosion Monitoring of Condensing Systems on Top of Decompression Towers
Fushun Petrochemical Company mainly processes Daqing crude oil as the main crude oil.In actual operation,it was found that the salt content of this crude oil fluctuates greatly,leading to prominent equipment anti-corrosion problems.Therefore,an equipment anti-corrosion management method with corrosion circuit and corrosion control manual technology as the core is adopted to control and solve the corrosion problem of the equipment.A corrosion circuit technical analysis was conducted on the atmospheric and vacuum distillation unit of Fushun Petrochemical.The unit is divided into a total of 19 corrosion circuits,of which 8 circuits have high-risk areas.Finally,the monitoring and testing strategy and integrity operation window for each circuit were determined during the corrosion control manual writing stage.Based on circuit analysis recommendations,online corrosion monitoring points have been established.Due to the high level of risk in the analysis of the cooling system circuit,a probe monitoring point was established.Through thickness measurement and review,it was found that the nearby 1m elbow had significantly reduced thickness,indicating that the probe had timely detected the corrosion risk.The application results of monitoring points indicate that the use of corrosion control manual technology can guide the scientific selection of corrosion monitoring systems,truly discover the corrosion risk of devices,and ensure safe production.
