“…The data of Elbishlawi and Spencer [14], Stepanova et al [21], Coan and King [12], Legret et al [15], Rijjkers et al [2] and Marteau et al [18] were measured in the same range of y1, p and T as our measurements. Our data are in reasonable agreement with most of these data though we note that the data of Elbishlawi and Spencer [14] and Legret et al [15] tend to deviate postively from our data.…”

New isothermal pTxy data are reported for methane + benzene and methane + methylbenzene (toluene) at pressures up to 13 MPa over the temperature range (188 to 313) K using a custom-built vapor-liquid equilibrium (VLE) apparatus. The aim of this work was to investigate literature data inconsistencies and to extend the measurements to lower temperatures. For methane (1) + benzene (2), measurements were made along six isotherms from (233 to 348) K at pressures to 9.6 MPa. At temperatures below 279 K there was evidence of a solid phase, and thus only vapor phase samples were analyzed at these temperatures. For the methane (1) + methylbenzene (3) system, measurements were made along seven isotherms from (188 to 313) K at pressures up to 13 MPa. Along the 198 K isotherms, a significant change in the data's p,x slope was observed indicating liquid-liquid equilibria at higher pressures. The data were compared with literature data and with calculations made using the Peng-Robinson (PR) equation of state (EOS). For both binary systems our data agree with much of the literature data that also deviate from the EOS in a similar manner. However, the data

“…We will begin our comparative analysis with methane-n-alkane systems, whose practical significance is well known and does not require additional comments. Usually, attempts to model the phase behavior of these systems are made by determining the optimum values for the binary adjustable parameters in the semi-empirical thermodynamic models applied (Marteau et al, 1997;Cebola et al, 2000). Though for equations such as SRK it is rather difficult to get sufficiently accurate results without t h e s e parameters, nevertheless the possibility has been conside r e d (Legret et al, 1984).…”

“…25 The measurements were carried out in the near-infrared range in order to overcome problems caused by strong absorption bands of CO 2 . 26,27 Marteau et al [28][29][30] employed a similar strategy for determining the high-pressure phase diagrams of hydrocarbon mixtures. Recently, Kazarian and his co-workers [31][32][33][34] applied the attenuated total reflection infrared (ATR-IR) method for studying polymer films and ionic liquids under high-pressure CO 2 .…”

A new continuous flow method using attenuated total reflection infrared (ATR-IR) spectroscopy has been developed for monitoring phase transitions in multicomponent fluids at high pressures and temperatures. Our approach uses Fourier transform infrared (FT-IR) and a modified Golden Gate attenuated total reflection (ATR) cell and exploits the fact that the absorbance of a vapor is much lower than that of the corresponding liquid to monitor the phase transition between vapor and liquid. We demonstrate that this method can provide quantitative measurements on both the dew point and the bubble point. We have validated our approach using three single-component systems (EtOH, MeOH, and H(2)O) and a binary system of EtOH + H(2)O, monitoring phase transitions at temperature up to 300 °C and pressure up to 10 MPa.
