Modelling the impact of stream impurities on ductile fractures in CO2 pipelines
Pressurised pipelines are considered to be the most practical method for transporting captured CO2 from fossil fuel power plants for subsequent storage. Funded by the EPSRC MATTRAN project, this work for the first time presents the development and validation of a fully coupled fluid-structure model for accurately predicting the material toughness required in order to avoid propagating ductile fractures in CO2 pipelines. The above model has been extensively employed by the authors to assist National Grid to determine the suitability of the current stock of UK natural gas pipelines for transporting CO2 for offshore storage pipelines.
