Abstract

Carbon Capture and Storage (CCS) is widely seen as an effective technique to reduce what are perceived to be excessive concentrations of Carbon Dioxide (CO2) in the atmosphere. In the CCS chain, transportation of CO2 through high-pressure pipelines constitutes an important link. Although CO2 pipelines are generally very safe, an unplanned release of CO2 from a pipeline presents a potential risk to human and animal populations as well as the environment. Therefore, to facilitate the risk assessment, it is necessary to gain a better understanding of CO2 releases from high-pressure pipelines, including the prediction of depressurisation of the pipe flow, the near-field atmospheric expansion and the far-field atmospheric dispersion.
