A modification of the martin equation of state for calculating vapour-liquid equilibria

A new cubic equation of state and its applications to the modeling of vapor-liquid equilibria and volumetric properties of natural fluids

“…Most of them aimed at the improvement in liquid volumes, such as the equations developed by Fuller (1976), Usdin and McAuliffe (1976), Peng and Robinson (1976), Schmidt and Wenzel (1980), Harmens and Knapp (1980), Heyen (1981), Kubic (1982), Aadachi et al (1983), Lin et al (1983), Yu andLu (1987), Trebble and Bishnoi (1987), Iwai et al(1988), Jan and Tsai (1991), Wang and Guo (1992), Nasrifar and Moshfeghian (2001), Sun (2002), and many others.…”

“…These phenomena result from their temperature dependence of the covolume b. (ii) The Heyen (1981) and Kubic (1982) equations yield very poor prediction of vapor pressures. (iii) The cubic chain-of-rotators equation, CCOR, developed by Lin et al (1983), has a good accuracy of liquid volumes, but it is less accurate than RKS and PR in saturation pressures and vapor volumes.…”

Comparison of the prediction power of 23 generalized equations of state: Part II — Parametric evaluation

“…The studied EOSs in the first part [1] were the RKS (RedlichKwong-Soave) [5], RKTCC (Redlich-Kwong-Twu-CoonCunningham) [15], RKNB (Redlich-Kwong-Nasrifar-Bolland) [16], HK (Harmens-Knapp) [17], PR (Peng-Robinson) [18,19], PRTCC (Peng-Robinson-Twu-Coon-Cunningham) [20], PRGGPR (Peng-Robinson-Gasem-Gao-Pan-Robinson) [9], KM (KubicMartin) [21], NB (Nasrifar-Bolland) [22], NM (NasrifarMoshfeghian) [23], MNM (modified NM) [24], TB (Trebble-Bishnoi) [25], TBS (Salim-Trebble-Bishnoi) [26], PT (Patel-Teja) [27], PTV (Patel-Teja-Valderrama) [28], KS (Kumar-Starling) [29], MKS (Chu-Zuo-Guo) [30], Jiuxun [31], MMM (Mohsennia-Modarres-Mansoori) [32], DPTG (Dashtizadeh-Pazouki-Taghikhani-Ghotbi) [33], LKP (Lee-Kesler-Plöcker et al) [34], BWRSH (Benedict-WebRubin-Starling-Han) [35] and BWRSHN (Benedict-WebRubin-Starling-Han-Nishumi) [36,37]. Details of the aforementioned equations (functional form and parameters) have been summarized in the first part [1] under six more general forms of TB, Martin, KS, Jiuxun, cubic hard-core and truncated Virial which encompass the others.…”

Comparative study of eight cubic equations of state for predicting thermodynamic properties of alkanes

“…In the VPT EOS the third parameter c is introduced in the attraction term and also a critical compressibility factor is employed in a , b and c . Kubic (1982) on the other hand determined the third parameter as function of temperature employing pure component vapour-pressure and second virial coefficient correlation of Tsonopoulos (1974). Yu and Lu (1987) used the deviation contours for several properties of pure alkanes and adjusted the third parameter of their proposed equation.…”
