Corrosion Control in Crude Units

This Petrogenium course can be tailored for awareness/inexperienced staff, for intermediate and for experienced personnel. Furthermore the course can be customized for a specific refinery, plant or unit. The option for post-course consultancy/help-desk support is also available.

Participants may include: operators, inspectors, integrity-, process- and project engineers and service company reps; engineers & managers responsible for the reliable and safe design and operation of crude units. Non-refinery personnel, e.g., service providers, chemical vendors and engineering contractors. Those involved in the design of crude units or equipment for crude units may also benefit.

The challenges of overhead corrosion, high temperature corrosion and fouling; Crucial process steps as desalting, caustic injection and overhead protection are treated in depth; some pitfalls of opportunity crudes; to operate a crude unit safer, more reliably and more sustainably.

1st & 2nd half day

• Atmospheric and Vacuum Distillation units.
• Feedstock: types and contaminants.
• Threats to integrity. Corrosion, cracking, fouling
• High temperature sulfidic corrosion and naphthenic acid corrosion. Interaction, operational effects.
• Aqueous corrosion in the column top and overhead system corrosion.
• Materials, protections, barriers and verifications.

3rd & 4th half day

• Desalters and desalter operation. Desalter types, grids, operating variables, efficiencies
• Caustic addition to crude: Why, What and How
• Overhead protection by injection of water, ammonia , inhibitors, amines: Why or why not; how?
• Fouling: causes, effects and remedies.
