| Abstract: | Pipeline is the optimal way in transporting large amounts of carbon dioxide (CO2) in CCUS (carbon capture, utilization and storage) technology industrial chain. In this paper, the research progress on decompression and fracture propagation of CO2 pipeline leakage was reviewed from aspects of experiment and computer simulation. The influence of phase state, pipe material and buried condition on crack propagation was analyzed. The influence of equation of state (EOS), impurity factor and theoretical model on experimental and simulation calculation were discussed. The EOS suitable for the establishment of decompression wave prediction model was summarized and the theoretical method and simulation software of fluid-structure coupling research, as well as the technical documentations for the design of CO2 transport pipelines, were mentioned. The scientific problems that need to be studied further in CO2 pipeline leakage decompression and fracture propagation control were summarized. Prospecting the research contents that need to be carried out include: ①establishing the EOS calculation model of multivariate mixture at three phase point and phase line, ②seting up the coupling relationship between the thermal properties of CO2 and crack propagation furtherly, ③establishing the stop criterion of pipeline fracture, and ④developing and optimizing the special crack stop devices to avoid fracture propagation for CO2 transportation pipelines. |
