Vapor–liquid equilibrium of methane and methane+nitrogen and an equimolar hexane+decane mixture under isothermal conditions

High pressure phase equilibrium of ternary and multicomponent alkane mixtures in the temperature range from (283 to 473) K

“…Other studies of ternary mixtures include those of Yang et al [23] for the system methane/n-butane/ n-octane, Uribe-Vargas and Trejo [24] for the system methane/n-hexane/n-decane and Blanco et al [25] who determined dew points of the ternary system methane/ethane/butane. As concerns the study of phase equilibria of multicomponent alkane mixtures, previous results have been published by Daridon et al [26] reporting phase behaviour of multicomponent mixtures composed of methane/n-decane/heavy fraction, the heavy fraction contained n-alkanes ranging from noctadecane to n-triacontane, Gonzalpour et al [27] analysed the vapour-liquid equilibrium of a 5component synthetic gas condensate containing methane/n-propane/n-pentane/n-decane/nhexadecane, Mørch et al [28] determined dew points of five synthetic natural gas (SNG) mixtures containing ethane/propane/i-butane/n-butane/n-pentane, Nourozieh et al [29] reported vapourliquid equilibrium data of the ternary system methane/n-decane/n-octadecane, Pauly et al [30,31] measured the phase equilibrium data of multicomponent systems composed of methane plus a heavy fraction which ranged from n-tridecane to n-docosane, Shariati et al [5,32] + which included alkanes, cycloalkanes, and aromatics, whereas Fenghour et al [33] determined bubble points of the multicomponent mixture composed of methane/n-butane/n-heptane/n-hexadecane.…”

Phase Behavior of the Butane + Decane Binary System

“…Therefore, by performing phase equilibrium measurements on simple mixtures, it is possible to come to a good understanding of the phase behavior of real reservoir fluids. Normal alkanes and normal alkane mixtures are among the most common representative systems that have been studied by a number of researchers. − Reamer et al and Reamer and Sage studied the binary system of butane + decane using a dynamic phase recirculation method for determining the equilibrium compositions.…”

High-pressure (vapor+liquid) equilibria in the (nitrogen+n-heptane) system

“…However, it is difficult to use these equations to predict correctly the complex phase behavior of (N 2 + crude oil) systems due to a lack of experimental phase equilibrium information of (N 2 + hydrocarbon) systems over wide ranges of temperature and pressure. In fact, most of the information on this subject refers to binary (N 2 + hydrocarbon) systems and only a few (N 2 + hydrocarbon) data are reported for ternary [10,15,32,[51][52][53][54][55], quaternary [32,56], and multicomponent [57] systems. Nevertheless, as pointed out by Grausø et al [9], many of the binary (N 2 + hydrocarbon) (vapor + liquid) equilibrium data reported in the literature are generally not internally consistent and mutually conflicting; i.e., there is a great deal of scatter among the experimental points.…”
