Fluid-Structure Interaction Analysis of Running Ductile Fractures in CO2 Pipelines With Toroidal Ring Crack Arrestors

Abstract The increasing need for carbon capture, utilization, and storage to mitigate greenhouse gas emissions has heightened interest in the safe transportation of carbon dioxide (CO2) through pipelines. CO2 is preferably transported in its dense phase or supercritical state. However, dense-phase CO2 pipelines are particularly susceptible to running ductile fracture due to the unique decompression characteristics during an accidental release, …
