Overview

This webinar will review and discuss all hypothetical and real world CCS corrosion modes.

This Webinar includes:

1. Corrosion due to strong acids, sulfuric acid and nitric acid
   - Potentially reactive species that can lead to creation of strong acids: SOx, NOx, H₂S, COS, CS₂, CO, O₂ and others
   - Carbon steel and CRA vulnerability to strong acids
2. Corrosion due to free water
   - Chemical reactions that can increase water content in a CCS network
   - Risks during commissioning and other operating modes
3. Corrosion due to induced aqueous phases
   - Corrosive aqueous phases induced by TEG, MEG, methanol, ethanol & propanol
   - Corrosion risk in dense phase pipelines
4. Erosion due to solids
   - Chemical reactions that can crease solids in a CCS network

Real world examples of corrosion and corrosion risk:

• As experienced on the Gorgon CCS project
• As experienced in Decatur, Illinois
• Chemical reactions and strong acids as demonstrated in laboratory conditions
• Corrosion risk as identified during design of CCS networks

Design solutions and mitigations:

• Setting a CO₂ quality specification
• Limits of existing models
