- Abstract:
- [Objective] With the development of carbon capture, utilization and storage (CCUS) technology, research on supercritical CO2 pipeline transportation technology is imperative. Basic research is the prerequisite to ensuring the safe and efficient operation of CO2 pipelines. [Methods] In this paper, the particularity physical properties of impure CO2 and its influence on the flow behavior in pipelines are discussed, the main methods and existing issues in the hydrothermal calculations for supercritical CO2 pipelines are summarized, and the experimental and theoretical research progress about decompression, leakage and diffusion of supercritical CO2 pipelines is elaborated. Finally, the future trends in theoretical and simulation research on supercritical CO2 pipeline transportation are outlined, in an attempt to enhance CO2 pipeline transportation and facilitate the development of CCUS technology in China. [Results] The captured CO2 contains a variety of impurities, which will shift the physical properties of CO2 and make the range of the two-phase zone larger, thus increasing the difficulty of phase control during pipeline transportation, so the impurities should be carefully considered in the simulation. Both the mathematical equations and solving algorithms of conventional oil and gas pipeline simulation technologies have made approximate treatments, which may not guarantee the prediction accuracy for supercritical CO2 pipelines. Therefore, the equations and algorithms should be improved to fit the new requirements according to the engineering data. Although the leakage and pressure reduction processes in supercritical CO2 pipelines are primarily understood, studies on the underlying mechanisms remain inadequate, and simulation methods need to be refined. It’s necessary to unify experimental conditions and propose more accurate physical and mathematical models. [Conclusion] Supercritical CO2 pipeline transportation technology demonstrates good prospects. Deep research on related theories and simulations is of great significance for breaking through the technical bottlenecks of CO2 pipeline transportation and promoting the development of the CCUS industry chain.
