3589 Good plant design for CO2 stream impurity measurement

Overview:

As carbon capture and storage (CCS) moves from concept to large-scale deployment, ensuring the safe, efficient, and commercially viable operation of CO₂ transport and storage networks is critical. One of the key challenges facing this emerging sector is the accurate measurement of impurities in captured CO₂ streams—an essential step to safeguard infrastructure, meet regulatory standards, and support commercial agreements.

This Good Practice Guide provides a comprehensive reference for developers, operators, and regulators. It outlines practical guidance on available and emerging technologies for measuring impurities—both on-line (real-time) and off-line (lab-based)—as well as insights into equipment selection, calibration standards, and the use of certified reference materials.

This guideline covers:

• Overview of key impurities and their operational and chemical impacts
• Measurement ranges and performance requirements
• State-of-the-art analysis of available and near-future technologies
• Practical considerations for equipment validation and system design
• A prioritized roadmap for closing current gaps in measurement capability
