Corrosion Risk Analysis and Control Suggestions of Atmospheric and Vacuum Distillation Unit

The change of processing load of atmospheric and vacuum distillation unit, the corrosivity of processing raw materials, and the control of electric desalination were analyzed. The corrosion control situation and corrosion risk of the low temperature system and high temperature part of the tower top of the device were systematically analyzed, and the corrosion control measures and suggestions were put forward.
