“…Chapoy et al measured and modeled a representative CO 2 -rich flue gas system in the presence of impurities (O 2 , Ar, and N 2 ). This study and other ones , showed that, even in small concentrations, the presence of these impurities changes the phase diagram of the system. In a joint industry project report on the impact of impurities on the CCS chain, Chapoy et al also reported four measurement points of hydrate dissociation of the CO 2 + O 2 mixture (5 mol % of O 2 ).…”

Knowledge of the dissociation conditions of mixed-gas hydrate systems is of great importance for scientific understanding (e.g. Clathrate hydrates in the outer solar system) and engineering applications (e.g. flow assurance, refrigeration and separation processes). In this work, CO 2 +O 2 hydrate dissociation points were measured at different O 2 mole fractions (11%, 32% and 50%) using isochoric pressure search method. The consistency of these new data was verified using the Clausius-Clapeyron relationship. The measurements performed for pressures up to 19 MPa overcome the lack of data for this system, and also allows to evaluate the model predictions from pure CO 2 hydrate to pure O 2 hydrate. To predict gas hydrate stability curves, in this work, the well-established hydrate theory of van der Waals and Platteeuw (vdWP) is combined with an electrolyte CPA-type Equation of State (e-PR-CPA EoS) which has been successfully used to represent with high accuracy the fluid phase equilibria (including gas solubility and water content) of complex systems containing gas, water and salt. The resulting model (e-PR-CPA + vdWP) was applied to the O 2 +H 2 O and CO 2 +H 2 O+(NaCl) systems by comparing with literature data. In the studied temperature range (>270K), the model predicts as expected a hydrate structure of type I for O 2 , CO 2 and their mixtures. An excellent reproduction of the measured data by this complete model was obtained without any additional adjustable parameters.

“…This is a result of an increase in the critical pressure of the mixture with an increase in the impurities content. In the same vein, it is believed that if the CO 2 stream with impurities reaches a two-phase situation along the pipeline, there will be a larger drop in pressure compared to the pure CO 2 stream [39,45,57,93,137] Finally, Cole et al [43] reported that the CO 2 transport pressure ranges between 50 to 100 bar.…”

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

“…Throughout the chain, there will be other components besides CO 2 , which will affect fluid properties and hence the performance of different processes. , Impurities will naturally occur before the CO 2 capture and in geological storage reservoirs. Depending on the process, the impurity level in captured CO 2 products varies significantly.…”

Liquid and Dense Phase Thermal Conductivity Measurements of CO₂ + N₂ and CO₂ + CH₄ Mixtures at Temperatures from 223 K to 308 K and Pressures up to 20 MPa

New data are presented for the thermal conductivity for CO 2 -rich binary mixtures in the liquid and dense phase, for temperatures between 223 and 308 K and pressures up to 20 MPa. Binary mixtures with mole fractions of 5% nitrogen and 5, 10, and 20% methane were investigated. Understanding the fluid properties of CO 2 -rich mixtures at relevant conditions is important for the deployment of efficient and robust systems for carbon dioxide capture and storage (CCS), but except that for water-rich CO 2 + H 2 O mixtures, no thermal conductivity data on liquid or dense phase mixtures including CO 2 are known to be reported prior to this work.
