Summary of the lecture
This technical guide offers an overview of the corrosion behavior of organic acids and provides guidance on selecting suitable stainless steels and nickel-containing alloys for their production, handling, and storage. It examines how variables such as temperature, pH, contaminants, and redox conditions influence corrosion performance in systems involving formic, acetic, propionic, butyric, fatty, and naphthenic acids. The document also outlines recommended alloys for different operational environments and highlights key considerations for preventing intergranular corrosion, pitting, crevice corrosion, and chloride stress-corrosion cracking.
What you will learn:
-
- Identify the main organic acids used in industry and describe their corrosive behavior under different conditions.
- Explain the factors that influence corrosion in organic acid environments, including contaminants, temperature, and redox potential.
- Differentiate between stainless steels and nickel-containing alloys commonly used in organic acid service.
- Select appropriate alloys for specific organic acid applications based on corrosion resistance and process conditions.
- Evaluate the risks of intergranular corrosion, pitting, crevice corrosion, and chloride stress-corrosion cracking in processing equipment.
- Apply alloy selection principles to real plant environments where mixtures of acids and contaminants may be present.
