“…In Aspen HYSYS, the equilibrium models SRK (Soave, 1972), PR (Peng and Robinson, 1976) and TST (Twu et al, 2005) are available for systems containing methane, CO2 and water. In the SRK-Twu and PR-Twu models, the original α-function is replaced by a function from Twu et al (1991).…”

“…Traditionally, gas mixtures of methane, CO2 and water are calculated in a process simulation program with standard models like PR (Peng and Robinson, 1976) and SRK (Soave, 1972). It is known that these models simulate the gas phase and the condensation point quite accurately at least below the critical point (46 bar for methane and 74 bar for CO2), but the resulting liquid phase may be questionable.…”

“…For the other systems, the computed BIPs are in agreement with BIPs used in Aspen Plus. Note that BIPs are typically temperature dependent [53][54][55], but Aspen Plus uses a temperature independent BIP for the investigated gas mixtures, which complicates a direct comparison with our results.…”

“…There is a limited number of articles available studying the calculations and models for vapour/liquid equilibrium in the methane/CO2/water-system (Austegard et al, 2006;Privat and Jaubert, 2014;Al Ghafri et al, 2014;Legoix et al, 2017). Austegard et al conclude that a simple equation of state like SRK is satisfactory to describe the vapour phase, but more complex models, e.g., SRK combined with a HV model is necessary to describe the liquid phase (Austegard et al, 2006).…”
