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.
