The Challenge:
Our client, a North American company, requested Fertilizer Industrial Services to develop a comprehensive guideline for engineering practice related to corrosion and selection of material specifically designed for ammonia plants.
Our Solution
We use international industry knowledge and ammonia plants site specific conditions to develop a comprehensive engineering practice covering topics such as:

- Desulphurization and Air-Compression
- Steam Reforming
- CO Conversion and Methanation
- CO2 Removal
- Syngas Compression
- NH3 Synthesis
- Refrigeration
- NH3 & H2 Recovery
- Steam and Condensate System
- Corrosion Mechanism
- Uniform Corrosion
- Selective (localized) Corrosion
- Crevice Corrosion
- Intergranular corrosion
- Stress Corrosion Cracking (SCC)
- Galvanic Corrosion
- Corrosion Fatigue
- Erosion
- Hydrogen
- High Temperature Hydrogen Attack (HTHA)
- Hydrogen Induced Cracking (HIC)
- Hydrogen Induced Stress Cracking (HISC)
- Sulphide Stress Corrosion
