CO2 transport

CO2 transport

CO2 capture and storage (CCS) is one of the most important ways to reduce global CO2 emissions. Since CO2 will usually not be captured and stored at the same place, we will in the near future have to transport large quantities of CO2, mostly by pipeline or ship. Our research shows how CO2 transport can be done in a safe and economical way.

We work within these areas:

  • Accurate measurements of the properties of CO2-rich mixtures (that is, CO2 with impurities)
  • Simulation of dynamic flow, depressurization and pressure-wave propagation in pipes and wells
  • Coupling between thermo and fluid dynamics (robust, accurate and efficient methods)
  • Coupled fluid-structure model to predict running-ductile fracture in CO2-transport pipelines (collaboration with SINTEF Materials and Chemistry)
  • The effect of impurities on the thermophysical properties and the flow
  • Heat transfer through pipes and wells
  • Ship transport of CO2

Method:

We have developed an in-house modelling framework for multiphase flow of CO2 and CO2-rich mixtures in pipes. The method has been developed to capture pressure waves, which is needed to model running fractures. Several different flow models and thermodynamic equations of state have been implemented. We have also developed a highly accurate laboratory set-up to measure phase equilibria for CO2-rich mixtures at conditions relevant for CCS. Such data are needed to develop accurate models for CO2 properties. We are currently designing and constructing two ECCSEL laboratories, one for depressurization of pipes and vessels, and one viscosity and density measurements.
