Revised Guidelines for CO2 Pipeline Transport: Addressing Impurities and Safety

The current revision of DNV-RP-F104 (2021) 1 provides guidance on typical carbon dioxide compositions to be expected within the context of CC(U)S, depending on the source from which the carbon dioxide is captured/extracted. The recommended practice (RP) provides guidance on what different impurity components (impurities) contained in the CO2 that may affect pipeline transport, considering safety, integrity and operability of onshore and offshore pipelines. Through a new joint industry project (JIP) established by DNV in 2023, it with was decided to revise the current recommendations for the CO2 specification based on the most recent knowledge and experience for CO2 transport to facilitate pipeline designers/operators in the process of setting up a CO2 specification. This work presents a guideline approach for setting up a project specific CO2 specification
