“…The experimental values of speed of sound obtained for water were compared with those from the reference EoS, and the precision (MRD( u )) obtained was better than 0.06%. The values of MRD( u ) obtained in this work are comparable with those from the literature − determined with pulsed ultrasonic systems operating in most of the cases up to pressures lower than those reached in this work. Using the same technique, Gedanitz et al measured sound velocity in fluids up to 30 MPa in the temperature range between 250 and 350 K, and the deviations observed in their measurements are better than those given above.…”

Quasicontinuous PρT data of CO(2), ethane, propane, and the [CO(2) + ethane] mixture have been determined along subcritical, critical, and supercritical regions. These data have been used to develop the optimal experimental method and to determine the precision of the results obtained when using an Anton Paar DMA HPM vibrating-tube densimeter. A comparison with data from reference EoS and other authors confirm the quality of our experimental setup, its calibration, and testing. For pure compounds, the value of the mean relative deviation is MRD(ρ) = 0.05% for the liquid phase and for the extended critical and supercritical region. For binary mixtures the mean relative deviation is MRD(ρ) = 0.70% in the range up to 20 MPa and MRD(ρ) = 0.20% in the range up to 70 MPa. The number of experimental points measured and their just quality have enable us to determine some derivated properties with satisfactory precision; isothermal compressibilities, κ(T), have been calculated for CO(2) and ethane (MRD(κ(T)) = 1.5%), isobaric expasion coefficients, α(P), and internal pressures, π(i), for CO(2) (MRD(α(P)) = 5% and MRD(π(i)) = 7%) and ethane (MRD(α(P)) = 7.5% and MRD(π(i)) = 8%). An in-depth discussion is presented on the behavior of the properties obtained along subcritical, critical, and supercritical regions. In addition, PuT values have been determined for water and compressed ethane from 273.19 to 463.26 K up to pressures of 190.0 MPa, using a device based on a 5 MHz pulsed ultrasonic system (MRD(u) = 0.1%). With these data we have calibrated the apparatus and have verified the adequacy of the operation with normal liquids as well as with some compressed gases. From density and speed of sound data of ethane, isentropic compressibilities, κ(s), have been obtained, and from these and our values for κ(T) and α(P), isobaric heat capacities, C(p), have been calculated with MRD(C(p)) = 3%, wich is within that of the EoS.

“…In this sense, the knowledge of the behavior of mixture properties as a function of composition, temperature, pressure, and chemical nature of its constituents is a central question in thermodynamic modeling. Among the applications, this knowledge may be employed when using thermophysical properties as process sensors; and has been used traditionally in the characterization of complex mixtures [1], such as petroleum containing mainly non-polar substances like long chain alkane, naphthenic, and aromatic compounds, with a wide range of carbon numbers [2].…”

“…This comparison is given in Figure 5 and Figure 6, and shows that the shale oil samples have relatively low compressibilities. The petroleum fraction was a narrow distillation cut with an average boiling point of about 523 K. 45 The bio-derived jet fuels consisted mostly of linear and branched paraffins (BIO-SPK and Cs-HRJ samples in 46 ). The curves shown in the figures were calculated by fitting polynomials to the experimental data given in the references and then using those polynomials to calculate the compressibility.…”

The temperature and pressure dependence of density was measured experimentally from 293 to 473 K and 0.1 to 12 MPa for a shale oil produced from Kukersite oil shale in Estonia. The shale oil sample was a fuel oil fraction of a whole oil produced in a commercial plant that uses solid heat carrier retorting technology. The fraction had a boiling range of approximately 460 to 780 K and contained significant quantities of polar phenolic compounds (hydroxyl group content of 5.3 wt%). The effect of these compounds on the properties of the oil was investigated by removing most of the phenolic compounds via extraction to create the second sample (dephenolated sample with hydroxyl group content of 1.1 wt%). The dephenolation resulted in a shale oil with a composition being more similar to that of other shale oils from well explored deposits. Based on a review of the literature, this is the first experimental data on the pressure dependence of density for this shale oil, and shale oils generally. Thermal expansion coefficients, isothermal compressibilities and speeds of sound were calculated from the experimental data. Empirical relationships describing the temperature dependence of the heat capacities between 288 and 423 K at atmospheric pressure are also presented here.
