Summary of the lecture
This course provides an in-depth study of corrosion mechanisms and alloy performance in wet-process phosphoric acid systems. Drawing on the Nickel Institute’s technical guidelines, it explores the influence of chemical contaminants, temperature, and process variables on the corrosion behavior of stainless steels and nickel-based alloys. Students will learn to evaluate material compatibility, identify corrosion risks, and select optimal alloys for equipment design, handling, storage, and transport within phosphoric acid production facilities. Case studies from industrial applications support a practical understanding of alloy behavior in complex environments.
What you will learn:
- Explain the principles of corrosion and passivation in pure and contaminated phosphoric acid environments.
- Differentiate between the corrosion resistance of austenitic, duplex, and nickel-based alloys under various process conditions.
- Analyze the effects of impurities such as chlorides, fluorides, and oxidizing ions on alloy degradation.
- Evaluate the performance of candidate materials for components including reactors, pumps, valves, and evaporators.
- Select appropriate alloys and protective linings based on process variables, mechanical requirements, and cost-effectiveness.
- Apply Nickel Institute guidelines to improve material reliability and minimize corrosion-related maintenance in phosphoric acid plants.
