Measurements of the(p,ρ,T) relation of methane and carbon dioxide in the temperature range 240 K to 520 K at pressures up to 30 MPa using a new accurate single-sinker densimeter

Multiparameter crossover equation of state: Generalized algorithm and application to carbon dioxide

“…2 and 3 show that the rep- [41,42], the representation of the data by MC EOS is similar to SW EOS except in the region of 337 K ≤ T ≤ 344 K, as shown in Fig. 4.…”

Modifying GMA equation of state for description of (P, ρ, T) relation of gas and liquids over an extended pressure range

“…On the other hand, IR EOS gives an excellent fit over the entire density range. Some insight into the possible reason for this behavior can be explained by expanding the van der Waals expression for (Z−1)v 3 to obtain (12) where b and a are the usual van der Waals parameters associated with repulsive and attractive interactions, respectively. We note that a term linear in ρ appears in the equation if the other terms can be neglected.…”

“…Therefore, densities of carbon monoxide, oxygen, methane (which were shown in Figs. [10][11][12] and nitrogen in gas phase are also calculated by GMA EOS and compared with experimental data in Figs. 13 We have also calculated saturated liquid and vapor densities of five components of Table 3 by IR EOS, and the AADs are reported in Table 4.…”

Solubility of carbon dioxide in aqueous solutions of diisopropanolamine and methyldiethanolamine

“…The second and third virial coefficients for CO 2 were regressed from the works of Klimeck et al [7] and of Span and Wagner [8]. The moles of CO 2 absorbed into the liquid phase were determined from Eq.…”
