چکیده انگلیسی
Transportation safety is a key aspect of carbon capture and storage (CCS), which is a major technology used to reduce greenhouse gas emissions. Supercritical CO2 pipelines have been certified as an optimised choice for CO2 transportation. The results of this study show that the Peng-Robinson (PR) equation of state is recommended for analysis of the properties of supercritical CO2. The influence of nonpolar and polar impurities on the two-phase region and the location of the sharp discontinuity in the density are found by analysing the ternary phase equilibrium and physical parameters using the PR equation of state. A transitional area between the supercritical phase and the dense phase, where the density changes abruptly, is defined as the quasi-critical region. This study describes the functional relation between the temperature and the pressure that defines the quasi-critical line by calculating the partial derivative equations and then determines the effect of impurities on the quasi-critical region of transported CO2. Operational recommendations for pipeline transportation of flue CO2 are developed using a pipeline operated by Sinopec as an example, demonstrating the influence of impurities in flue CO2 on saturation pressure for control and prevention of fractures in CO2 pipelines.
