“…It also showed that the heavy hydrocarbons had the effect of considerably increasing the saturation pressures. These observations were not really surprising, because they fitted into the logic of the behavior of methane-heavy hydrocarbon binary mixtures investigated experimentally at the University of Delft (van der Kooi, 1981;Glaser, Peters et al, 1985;Flöter, 1999), at IFP (Arnaud et al, 1996;LeRoy et al, 1997) and at the CNRS (Marteau et al, 1998). For example, we found the negative slope of the curve of appearance of a solid phase at high pressure in the (P, T), diagram, as it had been observed on methane rich binary mixtures (Fig.…”

“…Arnaud during his thesis project showed that the scale of the excess volume is significantly greater, raising the problem of its modeling. Volume translation has no influence on the excess volume in a cubic equation of state, but it is possible to introduce a quadratic mixing rule on the covolume to faithfully represent this quantity (Arnaud et al, 1996). Measurements of excess volume thereby provide independent information of the phase equilibria measurements, the former being rather influenced by the covolume mixing rule and the latter by the attractive term of the equation of state.…”
