“…The article provided temperature and pressure profiles over time at the first end and second end of the pipeline during the process. Here, we computed the densities and speed of sound for the pairs of pressure and temperature obtained from the graphs of [11] at different time steps of the first end. We conducted the numerical simulations for three compositions using SPUNG and SRK.…”

“…The two articles also provided a literature survey on CPA and SAFT type developments and recent achievements. Here, we used the Extended Corresponding States (ECS) EoS SPUNG for the prediction of thermodynamic properties over a PVTx of two sets of CO2 depressurization experimental data [11], [12]. The results were compared to the cubic EoS SRK, which was chosen because of its popularity in industry and low computational cost.…”

“…This might make the coupling to a flow solver and running a multi-component and multi-phase simulations feasible. In this study only thermodynamics was regarded, and the sets of PT pairs over which the predictions were conducted, were taken at different time steps from real experimental depressurization conditions [11], [12].…”

The proper modeling of CO2 depressurization is very important for the design for safety of a pipeline. One key element of the modeling process is the thermodynamics and transport properties modeling. In this work, an analysis of the error in thermodynamics for modeling CO2 at depressurization conditions was conducted. For the study presented here, the sophisticated equation of state (EoS) SPUNG was used. The results were compared to an EoS of a different level of complexity and, consequently, accuracy. This EoS is the cubic equation Soave-Redlich-Kwong (SRK) with van der Waal's mixing rules. The results show the significance of the thermodynamics modeling at a set of pressures, temperatures and compositions PVTx over time steps complying with two sets of experimental data.

“…The data gathered from this experiment were used to validate simulations of CO 2 release and dispersion [24,30,235,236,238]. From the material integrity viewpoint, it is necessary to have control of the rate of depressurisation, as too fast depressurisation can accelerate the temperature drop rate within the pipeline that can make the steel wall brittle [96,157,239]. …”

Transport of carbon dioxide (CO 2 ) via pipeline from the point of capture to a geologically suitable location for either sequestration or enhanced hydrocarbon recovery is a vital aspect of the carbon capture and storage (CCS) chain. This means of CO 2 transport has a number of advantages over other means of CO 2 transport, such as truck, rail, and ship. Pipelines ensure continuous transport of CO 2 from the capture point to the storage site, which is essential to transport the amount of CO 2 captured from the source facilities, such as fossil fuel power plants, operating in a continuous manner. Furthermore, using pipelines is regarded as more economical than other means of CO 2 transportThe greatest challenges of CO 2 transport via pipelines are related to integrity, flow assurance, capital and operating costs, and health, safety and environmental factors. Deployment of CCS pipeline projects is based either on point-to-point transport, in which case a specific source matches a specific storage point, or through the development of pipeline networks with a backbone CO 2 pipeline. In the latter case, the CO 2 streams, which are characterised by a varying impurity level and handled by the individual operators, are linked to the backbone CO 2 pipeline for further compression and transport. This may pose some additional challenges.This review involves a systematic evaluation of various challenges that delay the deployment of CO 2 pipeline transport and is based on an extensive survey of the literature. It is aimed at confidence-building in the technology and improving economics in the long run. Moreover, the knowledge gaps were identified, including lack of analyses on a holistic assessment of component impurities, corrosion consideration at the conceptual stage, the effect of elevation on CO 2 dense phase characteristics, permissible water levels in liquefied CO 2 , and commercial risks associated with project abandonment or cancellation resulting from high project capital and operating costs.2
