CO2PIPETRANS Work Package 1: CO2 Model Validation Data Collection and Public Sharing
Hamish Holt - DNV KEMA
WP1 of the CO2PIPETRANS JIP has the goal of collecting and making available in the public domain
suitable data that can be used for CO2 release model development and validation. The presentation
will provide an overview of the work that has been undertaken at the Spadeadam test site to collect
and share release and dispersion data from liquid and supercritical CO2 releases up to 150 bar and
150°C through orifices up to a diameter of 25 mm. The presentation will also present details of pipe
depressurisation tests that are due to be completed in November and much larger dispersion releases
that are being planned for early next year.
Using the CO2PIPETRANS Data: Phast Validation for CO2 Releases
Henk Witlox - DNV Software
This presentation will present and discuss the validation of discharge and subsequent atmospheric
dispersion for pressurised CO2 releases using the consequence modelling package Phast based on
experimental data shared by the CO2PIPETRANS JIP.
CO2PIPETRANS Work Package 2: CO2 Pipeline Fracture Arrest Experiments
Sigbjørn Røneid - DNV Maritime and Oil & Gas
DNV, through WP2 of the CO2PIPETRANS JIP is managing test site work that is undertaking
propagating crack experiments to collect crack propagation data for CO2 pipelines. This presentation
will provide an overview of the propagating crack experiments undertaken in Norway and will also
give details of the further large scale work planned for next year.
CO2PIPETRANS Work Package 3: CO2 Corrosion Experiments
Sigbjørn Røneid - DNV Maritime and Oil & Gas
The objective of WP3 of the CO2PIPETRANS JIP is to determine the corrosion mechanism and the
corrosion rate of carbon steel in liquid and supercritical phase CO2 with various amounts of impurities
like O2, H2, SOx, NOx, and H2S with water present at 50 and 500 ppmv. A large number of autoclave
experiments have been performed with various combinations of impurities and the results will help
determine a safe operating window for CCS projects. The presentation will provide an update on
progress of this work.
CO2PipeHaz: Materials and Safety Considerations for CO2 Pipeline Transportation
Haroun Mahgerefteh - University College London
Pipelines are considered as the most reliable and cost effective way of transporting large amounts of
CO2 over long distances for Carbon Capture and Sequestration (CCS). Given that CO2 is an asphyxiant
at high concentrations the safety of CO2 pipelines is central to the public acceptability of CCS as a
viable means of combating the impact of global warming. Factors affecting the accurate hazard and
risk assessment of CO2 pipelines include corrosion, hydrate formation and propensity to fast running
ductile and brittle factures. Special consideration is given to the impact of impurities in the CO2 stream
captured using various technologies on the above hazards. Some recent progress concerning the
knowledge gaps in the modelling of outflow and subsequent dispersion of CO2 following the
accidental rupture of pressurised CO2 pipelines will be presented.
