Crude Oil Distillation (CDU/VDU)

Crude oil distillation unit (both atmospheric and vacuum parts) is one of the key refinery process units. Increasing sulfur and acid content in processed crude slates necessitates a distillation unit that is adaptable and flexible enough to accommodate a wide array of feedstocks. This, however, may amplify certain corrosion damage mechanisms like sulfidation or naphthenic acid corrosion to levels considered unacceptable. The upcoming chapter provides a comprehensive overview of the crude distillation process emphasizing areas and types of corrosion damage mechanisms. Additionally, it includes links to detailed information, diagrams, and practical calculation tools.
