“…The average u M (ρ) was evaluated as 0.029 kg•m −3 . As proposed in the literature 36 and in our previous work, 37 a tiny change of composition could cause a density variation of the CO 2 −CH 4 binary system, especially in the vicinity of the critical point. The uncertainty resulting from the composition uncertainty can be calculated roughly by eq 9 using the GERG EoS, 49 as suggested in the literature 36,37…”

“…The sinker's volume V(T, P) is related with the reference volume V 0 at the reference temperature T 0 and reference pressure P 0 . 37 The standard deviation, resolution, and uncertainty of the MSB for density measurement were ±30 μg, 8 × 10 −7 g•cm −3 , and ±(0.1% + 4 × 10 −6 g•cm −3 ), respectively.…”

“…The relative deviations for x = 0.0998, 0.2017, and 0.3997 are relatively smaller, approximately below ±2%. Moreover, the experimental data from Liu et al 37 in the vicinity of the critical point of CO 2 in the temperature range 300−308.15 K and the pressure range 2−18 MPa were considered for comparison. The relative deviations for Liu et al 37 and this work are plotted versus density in Figure 6 at different CO 2 mole fractions.…”

“…The PVTx properties of the CO 2 –CH 4 binary system have been studied from experimental measurement and EoS modeling through past decades. The experimental PVTx properties of CO 2 –CH 4 binary mixtures have been measured by predecessors − for decades and were introduced, more or less, by Rivas et al, Yang et al, and Liu et al Figure summarizes the details of the density measurements from the literature. The densities of CO 2 –CH 4 systems have been measured by the isochoric (constant volume) method, Burnett method, vibrating-tube densimeter, magnetic suspension balance, and other methods.…”

Accurate density data and a predictive equation of state (EoS) for the CO2–CH4 system are significantly important for the application of natural gas purification and carbon capture, utilization, and storage (CCUS). In this work, densities of the CO2–CH4 binary system with CO2 mole fractions ranging from 0.0998 to 0.8988 were measured at temperatures of 313–353 K and pressures of 3–18 MPa using a magnetic suspension balance, and the compressibility factors and the relative combined standard uncertainties were also calculated correspondingly. The PC-SAFT EoS was employed for the density modeling, and the PR EoS was used for comparison. The measured density data in this work and experimental density data from the literature were used to optimize the binary interaction parameter k ij in the PC-SAFT EoS and PR EoS. The predicting abilities of PC-SAFT and PR EoS with the optimized k ij were compared to the case without binary interaction (k ij = 0). The PC-SAFT EoS with the optimized k ij had better performance than the PR EoS with optimized k ij , and it could predict the density properties of the CO2–CH4 system accurately, with an average absolute deviation (AAD) of 1.16%. Modelings from PC-SAFT with and without the optimized k ij were then compared with the measured densities obtained in this work. The relative deviations for the calculation from PC-SAFT with the optimized k ij were within the range from −3.93 to 2.94%. Moreover, the CO2–CH4 binary systems with CO2 mole fractions of 0.7985 and 0.8988 in this work can be regarded as CO2-rich fluids, and their density reductions compared with pure CO2 were evaluated for the measured density data and the values calculated from the modified PC-SAFT.
