Vapor-liquid equilibrium in binary and ternary mixtures of nitrogen, argon, and methane

Investigation on Vapor–Liquid Equilibrium of (Argon + Methane) at the Temperature Range of (95 to 135) K

“…Need to explain: PR equation of state combined with four mixing rules was selected to correlate the VLE data of the mixture (Ar (1) + CH 4 (2)), this is because PR equation is the most commonly used equation and can overcome the shortcomings of the SRK equation in calculating the molar volume of liquid phase . MHV1 mixing rule combined with four equations of state was selected to correlate the VLE data of the mixture (Ar (1) + CH 4 (2)), this is because, compared to other mixing rules, MHV1 mixing rule can all attain higher correlation accuracy in predicting phase equilibrium of different types of mixtures in natural gas. ,,- …”

“…In 2)), this is because, compared to other mixing rules, MHV1 mixing rule can all attain higher correlation accuracy in predicting phase equilibrium of different types of mixtures in natural gas. 5,12,[28][29][30][31][32][33][34][35] In order to compare the experimental results and calculated results within the wide temperature range, VLE data of (Ar + CH 4 ) published in other literatures were also added to be correlated with the VLE data in this work together, and the correlated results were shown in Table 3 and Table 4. The pressure deviations and composition deviations of (Ar + CH 4 ) between experimental results and calculated results from different models were shown in Figures 2−5, and the relationship about excess Gibbs free energy and excess enthalpy with composition of (Ar + CH 4 ) were given in Figures 6 and 7.…”

Analysis and optimization of two-column cryogenic process for argon recovery from hydrogen-depleted ammonia purge gas

“…Fig. 2 is that of binary mixture nitrogen-argon at 122.89 K measured by Jin et al (Jin et al, 1993) and Fig. 3 is that of ternary mixture nitrogen-argon-methane at 90.67 K, 122.89 K and 123.4 K measured by Sprow et al (Sprow and Prausnitz, 1966;Gravelle and Lu, 1973;Jin et al, 1993).…”

Development of kinetic Monte Carlo and Bin-Monte Carlo schemes for simulation of mixtures – vapor–liquid equilibria & adsorption

“…We chose three binary vapour-liquid equilibria for study: (i) both components were well below their critical temperature (T c ) (argon-methane at 122.89 K and argon-nitrogen at 112 K); (ii) one component is close to its critical temperature and the other is well below T c (argon-krypton at 148 K) and (iii) one fluid is above T c and the other is well below T c (argon-krypton at 177 K). Experimental data are available in the literature for these binary mixtures at these temperatures in references: Jin et al (1993), Miller et al (1973) and Schouten et al, (1975) respectively. To avoid lengthening the paper unnecessarily, we present briefly the results for the first system in the Appendix and the last two systems in detail, since if the new methodology works for these systems, it follows that it will work for systems under subcritical conditions.…”
