New experimental data to boost CO2 pipeline design

First-of-its-kind data relating to the depressurisation of CO2 pipelines is being made freely available through industry cooperation. This will help fill knowledge gaps associated with the safe and reliable pipeline transport of CO2 and result in cost efficiencies through a significantly improved design basis for CO2 pipelines.

The DNV GL-led CO2PIPETRANS joint industry project (JIP), which is now releasing new data, focuses on the transportation component of Carbon Capture Utilisation and Storage (CCUS) projects. “This new data is one step in the right direction. It builds on the success of previous experimental data released by DNV GL and can be used by the CCS industry and designers to validate computer simulations used in CO2 pipeline design, thus optimising the design process”, says Project Manager Jock Brown, DNV GL – Oil & Gas.

The datasets contain the results of depressurisation tests on a CO2 pipeline collected at the DNV GL Spadeadam test site in the UK as part of the second phase of the CO2PIPETRANS JIP started in 2011. In addition to making datasets for model validation publicly available, the JIP also involves work to improve the understanding of CO2 pipeline propagating cracks and corrosion rates with various CO2 stream impurities.
