Phase equilibria of (Methylbenzene + Carbon dioxide + Methane) at elevated pressure: Experiment and modelling

Solid-fluid equilibrium measurements of benzene in methane and implications for freeze-out at LNG conditions

“…The relative uncertainty of the benzene mole fraction in the mixture was taken as 1 % for both 199, 700, and 1012 ppm mixtures, as specified by the supplier. As detailed in Al Ghafri and Trusler (2019) [18], the uncertainty associated with the dilution of the methane + benzene mixture with pure methane was calculated by combining in quadrature the uncertainties arising from the syringe pump (ISCO) volume injections, visual cell volume, the fluid density under the pump temperature and pressure conditions, dead volumes of the injection lines, the purity of the chemicals used in this study, and the mole fraction of benzene in the gas mixture. The mixture's density was obtained from the default equation of state (EOS) implemented in the software package REFPROP 10.0 [19].…”

Density and Phase Behavior of the CO2 + Methylbenzene System in Wide Ranges of Temperatures and Pressures

“…The measurements were made out in specialised apparatus and are supported by a detailed assessment of uncertainty. [45][46][47][48] The new experimental data are compared with predictions from the SAFT-γ Mie and PPR-78 equations of state. The data could also be used to optimise binary interaction parameters in either traditional CEOS or the MFHEOS for CO2 + hydrocarbon system.…”

“…Therefore, the present work significantly extends the experimental range of density data for the (CO 2 + methylbenzene) system to include high-temperature and high-pressure states relevant to CO 2 -EOR. The measurements were made out in specialized apparatus and are supported by a detailed assessment of uncertainty. − The new experimental data are compared with predictions from the SAFT-γ Mie and PPR-78 equations of state. The data could also be used to optimize binary interaction parameters in either traditional CEOS or the MFHEOS for CO 2 + hydrocarbon system.…”

Experimental determination and modelling of high-pressure phase behavior for the binary system CO2 + cyclooctane

“…Phase equilibrium data of mixtures containing carbon dioxide are therefore still needed to design and improve industrial operations as well as to estimate the parameters of thermodynamic models [8][9][10].…”
