Liquid–vapour and solid–fluid equilibria for the system methane + triacontane at high temperature and high pressure

High pressure solid–solid and solid–liquid transition data for long chain alkanes

“…The data presented here complement the few studies existing in the literature [10][11][12][13][14]16,23,24] on the phase behaviour of n-alkanes at high pressures. When compared with published data, the agreement between the data presented here and the published data is almost perfect.…”

“…Again the solid-solid transition peak is followed at higher temperatures by the melting peak. In figure 10 the data measured in this study are compared with the solid-liquid data of Machado et al [24], which was determined using a visual technique. We see, in general, a good agreement with some slight deviations at higher pressures, which can be explained by the difficulty of working at such high pressures.…”

Modelling the phase behavior of alkane mixtures in wide ranges of conditions: New parameterization and predictive correlations of binary interactions for the RKPR EOS

“…(7)(8)(9)(10) together with the constants in Table 3 are graphically condensed in Figs. 6 to 8 show the predicted critical lines, together with available experimental data for the methane, ethane and propane series of binary systems respectively.…”

“…(1995) [7] for C 1 + C 20 , Flöter et al (1997) [8] for C 1 + C 24 , Machado and de Loos (2004) [9] for C 1 + C 30 and Marteau et al (1998) [5] for C 1 + C 36 . Moreover, it is very difficult to find results comparable to those presented in our previous work [1].…”

High pressure phase equilibria in methane+waxy systems

“…A heavy alkane with an odd number of carbon atoms was chosen since mixtures of paraffins crystallise in an orthorhombic structure similar to that presented by pure odd paraffins. A number of binary methane + paraffin systems have been studied previously [8][9][10][11][12][13] but most of them used paraffins with an even number of carbon atoms. Therefore, the investigation of this system was necessary to evaluate the effect of the crystalline structure on the phase diagram before carrying out studies on complex waxes.…”
