High-pressure vapor-liquid equilibria with cubic equations of state

Mutual solubilities of hydrocarbons and water: III. 1‐hexene; 1‐octene; C10C12 hydrocarbons

“…In addition, the PR EoS with Huron-Vidal mixing rules predicts a somewhat lower three-phase critical end point than it does with the van der Waals mixing rules. This confirms the previous similar observations by Tsonopoulos and Heidman (1986) for the water/ethylbenzene mixture. Many other mixing rules can be found in the literature.…”

Computational aspects of equations of state: Fact and fiction

“…I n our opinion, the perception that industry will only accept cubic equations-or at least algebraically simple models-has hindered progress toward the development of effective models based upon statistical mechanics. An important fact is that the simple cubic equations work very well (Tsonopoulos and Heidman, 1986). Industry will not and should not replace them with more sophisticated but less accurate and less reliable models whose only strength is their link to theory.…”

Characterization of water-containing reservoir oil using an EOS for steam injection processes

“…In this subsection, the significance of Equation (4) is elucidated by comparing predictions made using it with those made with a BIP value of 0.5, which is a representative value from the literature (Heidman et al, 1985;Peng and Robinson, 1976b;Tsonopoulos and Heidman, 1986;Nasrifar and Moshfeghian, 2002;Eubank et al, 1994;Mohebbinia et al, 2013;Søreide and Whitson, 1992). Equation (4) gives a much lower value of 0.242 for water with heavy nalkanes (see Table 1).…”
