Global thermodynamic behaviour of supercritical fluids: example of methane and ethane
Laboratoire de Synthèse et de Biocatalyse Organiques, Faculté des Sciences, Département de Chimie, Université Badji Mokhtar, B.P 12, Annaba ( 23200), Algerie
Do to the fluctuations associated with the critical region of fluids. The behavior of thermodynamic properties these can not be predicted by mean field theories. To do so, a global equation of state based on the crossover model has been used. This equation of state is formulated on the basis of comparison of selected measurements of pressure-density-temperature data, isochoric and isobaric heat capacity of fluids.The model can be applied in a wide range of temperatures and densities around the critical point for ethane and methane. It is found that the developed model represents most of the reliable experimental data accurately.
