“…The lowest isotherm of Lin et al (1979) coincides with our measurements at 423 K. Measurements by Elbishlawi and Spencer (1951) are in the range of the present work, but their data have been cited as possibly inaccurate (Legret et al, 1982). As a result, we decided to perform the measurements reported here.…”

Solubility data are presented for methane in toluene at temperatures of 313.2, 338.7, and 423.2 K at pressures to 8.9 MPa. The data are in reasonable agreement with the measurements of Lin et al. at 423 K but differ significantly from those of Elbishlawi et al. at 338.7 K. Our data can be described with root-mean-square deviations of about 0.0005 in mole fraction by the Soave-Redlich-Kwong and PengRobinson equations of state when a single interaction parameter per isotherm is employed in the equations.

“…The experimentally measured equilibrium liquid and vapor compositions for the mesitylene-methane system are presented in Table I and alted equilibrium ratios for each component in the binary system at each of the three temperatures are also given in Table 1 and are shown in Figure 2. The results of Legret et al ( 1982) in the binary system at their lower pressure region (two pressure points at 10.17 MPa and 14.45 MPa) at 313.2 K , are included in Figures I and 2 for comparison. The results are in reasonably good agreement with those obtained in this work, although there is some discrepancy in the nitrogen content of the liquid phase.…”

“…(1982) on methane and carbon dioxide with rn-xylene, and by Huang and Robinson (1983) on hydrogen sulfide with rn-xylene and with mesitylene. Legret et al (1982) studied the liquid-vapor equilibrium relations in the mesitylene-methane system over a wide range of pressure, up to the critical pressure and to a temperature of 313.2 K . Their results are included in this report for comparison.…”

Vapor and liquid equilibrium phase compositions have been determined at 310.9, 394.3, and 477.6 K for the mesitylene–methane binary system and at 310.9, 338.7, 394.3, and 477.6 K for the mesitylene–carbon dioxide system. At each temperature, the pressure ranged from the vapor pressure of mesitylene to about 15 MPa, although in the case of the mesitylene–carbon dioxide system, pressures were extended to the vicinity of the critical region at about 18 MPa. The data were used to calculate equilibrium ratios for each component in the binary system.

Paper based on a presentation at the 20th International Conference on Chemical Thermodynamics (ICCT 20), 3–8 August 2008, Warsaw, Poland. Other presentations are published in this issue, pp. 1719–1959International audienceIt is of utmost importance to have accurate experimental data available in order to develop accurate modeling for scientific and engineering purposes as it is emphasized through several herein-reported discussions with reknown scientists and engineers. Many methods are used to determine phase equilibria. Classification of the methods is not straight- forward as several basic principles can be mixed in several different ways. In this paper, we have selected some techniques, developed in our laboratory, to illustrate one type of classifi- cation. Several apparatuses are described. The techniques where all phases are analyzed are very often preferred to those relying on partial determinations requiring data treatment through models. The internal analyses by means of spectroscopic or other in situ analysis techniques are not applicable every time. Then, sampling devices are necessary. Sampling de- vices must be reliable and lead to extract sample amounts small enough not to disturb the equilibrium under study. The ROLSITM sampler developed at MINES ParisTech is a very powerful device allowing one to work up to 100 MPa, 850 K, with corrosive components and with samples from 1 μg to some mg. Applications of this sampler are described for funda- mental research (phase equilibrium measurements) and industrial purposes (process control and monitoring)
