NACE 34103

The objective of this report is to provide a document to help predict corrosion rates and point out areas of vulnerability in the distillation equipment associated with hydroprocessing units. It is intended for use by corrosion engineers and fixed-equipment inspectors. The report summarizes recent corrosion rate and materials of construction data collected from operating hydroprocessing units and compares them to previously developed corrosion rate curves, based on data from numerous refinery units.
