Solomon Brown received a Masters degree in Mathematics from King’s College London 2007. He went on to work on modelling the consequences of pipeline failure for which he obtained his PhD in 2011. His main research interest is in the area of computational fluid dynamics applied to safety and loss prevention.

Title: CO2PipeHaz: Quantitative Failure Consequence Hazard Assessment for Next Generation CO2 Pipelines

Supervisor: Prof Haroun Mahgerefteh

It is now generally accepted that the release of CO2 into the atmosphere is a major cause of the growing problem of climate change. The need to reduce the levels of CO2 into the atmosphere from power production is thus ever more pressing. As the reliance on hydrocarbons for the satisfaction of our energy requirements remains extremely high, the development of Carbon, Capture and Storage (CSS) is of extreme importance in emissions reduction.

The transportation of large inventories of CO2 from the capture site to the point of sequestration means that it is inevitable that highly pressurised pipelines will have to be used. Wide experience in the Oil and Gas industry with pressurised pipelines shows that the risk of their failure is not insignificant. Due to the properties of CO2, e.g. it's high Joules Thompson coefficient, modelling the behaviour of such a fluid upon failure of a pressurised pipeline represents a unique set of challenges.

The CO2PipeHaz project (http://www.co2pipehaz.eu) is focused on the assessment of hazards associated with an accidental rupture of a high-pressure pipeline transporting supercritical carbon dioxide (CO2). A number of challenges are faced in this area, ongoing work includes:

  • The accurate modelling of the thermodynamic state of CO2 and CO2 mixtures during depressurisation
  • Modelling of ductile fracture propagation in CO2 pipelines
  • Dispersion of CO2 after release
  • The effect of Emergency Shut Down Valves on the flow following pipeline failure.
