“…In the experiments in the present work, the temperature and pressure were the independent variables. The equilibrium cell, kept at constant temperature using a thermostatic bath, was filled with both CO 2 and O 2 until both liquid and vapor phases were present. A stirrer was used to mix the content to a stabilization of the temperature and pressure at their equilibrium values.…”

“…It follows Westman et al [1], which investigated the VLE of the CO 2 +N 2 system. The need for new data for these systems and the other mixtures relevant for carbon capture, transport and storage (CCS) has been discussed for instance in the recently reported comprehensive literature studies by [2,3,4,5]. Calculations using existing equations of state (EOS) [3,6] show that even small amounts of impurities in CO 2 -rich mixtures can significantly affect the behavior of the fluid [5,7].…”

Accurate thermophysical data for the CO 2 -rich mixtures relevant for carbon capture, transport and storage (CCS) are essential for the development of the accurate equations of state (EOS) and models needed for the design and operation of the processes within CCS. Vapor-liquid equilibrium measurements for the binary system CO 2 +O 2 are reported at 218, 233, 253, 273, 288 and 298 K, with estimated standard uncertainties of maximum 8 mK in temperature, maximum 3 kPa in pressure, and maximum 0.0031 in the mole fractions of the phases in the mixture critical regions, and 0.0005 in the mole fractions outside the critical regions. These measurements are compared with existing data. Although some data exists, there are little trustworthy literature data around critical conditions, and the measurements in the present work indicate a need to revise the parameters of existing models. The data in the present work has significantly less scatter than most of the literature data, and range from the vapor pressure of pure CO 2 to close to the mixture critical point pressure at all six temperatures. With the measurements in the present work, the data situation for the CO 2 +O 2 system is significantly improved, forming the basis to develop better equations of state for the system. A scaling law model is fitted to the critical region data of each isotherm, and high accuracy estimates for the critical composition and pressure are found. The Peng-Robinson EOS with the alpha correction by Mathias and Copeman, the mixing rules by Wong and Sandler, and the NRTL excess Gibbs energy model is fitted to the data in the present work, with a maximum absolute average deviation of 0.01 in mole fraction.

“…A number of research groups have studied some of these key binaries, such as CO2/N2 (Fandino et al, 2015;Mantovani et al, 2012;Tenorio et al, 2015;Westman et al, 2016b), CO2/Ar (Coquelet et al, 2008;Köpke and Eggers, 2007;Mantovani et al, 2012;Yang et al, 2015a), CO2/H2 (Cipollina et al, 2007;Fandino et al, 2015;Sanchez-Vicente et al, 2013;Tenorio et al, 2015), CO2/O2 (Mantovani et al, 2012;Westman et al, 2016a), CO2/SO2 (Coquelet et al, 2014;Köpke and Eggers, 2007), CO2/CO (Cipollina et al, 2007), CO2/H2S (Chapoy et al, 2013a) and CO2/H2O (Hou et al, 2013;Valtz et al, 2004), which either focused on the binaries with an insufficient amount of data under the conditions relevant to CCS or aimed at reducing experimental uncertainties. A comprehensive data survey of the available thermodynamic properties of binary systems with CO2 can be found in the monograph by Kunz et al (2007) and in the recent reviews by Munkejord et al (2016) and Li. et al (2011).…”

The p-T phase diagrams of two ternary systems (CO2 + Ar + N2 and CO2 + Ar + H2) have been measured at temperatures between 268 and 303 K using a fibre-optic phase equilibrium analyser. CO2, which is the major component, has a mole fraction ranging from 0.90 to 0.98 in both systems. The molar ratio of the two minor components is Ar:N2 = 1:1 and Ar:H2 = 2:3, respectively for the two ternary systems. In addition, the density of a ternary mixture with xAr =

An experimental investigation on pressure response and phase transition of supercritical carbon dioxide releases from a small‐scale pipeline

The prediction of the pressure response and phase transition in the event of an accidental carbon dioxide (CO 2 ) release from a ruptured pipeline is of significant importance for understanding the depressurization behaviour and hence the fracture behaviour. This article presented a small-scale experimental investigation on the pressure response and phase transition of supercritical CO 2 release from a pressurized pipeline with a relief orifice. High-frequency transducers and thermocouples were used to measure the evolution of CO 2 pressures and temperatures at different locations after release. The results indicated that pressures at different locations decreased nearly synchronously after release. No vapour bubble and pressure rebound generated in larger scale release experiments were found in our small-scale release experiments. The depressurization rate was greatly affected by the phase transition. During the release process, the supercritical CO 2 firstly turned into an unstable gas with a very great depressurization rate, then changed into the gas-liquid phase with a lower depressurization rate, and finally changed into gaseous CO 2 . The larger the relief diameter was, the longer the gas-liquid phase state lasted.
