Equipment Corrosion Monitoring of Refinery Process Units in Maoming Petrochemical Company

As the refinery of Maoming Petrochemical Company mainly processes the high-sulfur crude oils, the corrosion management and online monitoring and testing of the equipment corrosion were strengthened to ensure safe and reliable operation of the refinery process units. The corrosion monitoring probe was installed at each location subject to corrosion, the thickness of the elbows of the pipes was measured at the predefined location and prefixed time and corresponding corrosion profiles were produced. Over 500 storage tanks were inspected for corrosion and corrosion files were established. In addition, the automatic pH control system was installed at the overhead of the distillation unit and automatic chemical dosing system was provided in cooling water plant.
