“…In addition, experimental density data are reported for the propane-n-eicosane (C 3 + C 20 to our knowledge have not been previously reported. The results in this study complement our previously published pure-component hydrocarbon density studies at HTHP conditions [8,9].…”

a b s t r a c tBinary mixture density data are reported for propane (C 3 ) with n-decane (C 10 ) and with n-eicosane (C 20 ) at T = (320 to 525) K and pressures to 265 MPa. The (C 3 + C 10 ) mixture density data are in good agreement with available literature data to 70 MPa, which is the maximum reported literature pressure. There are no available binary mixture density data to compare to the (C 3 + C 20 ) mixture density data reported in the present study. The mixture density data are correlated with the Tait equation to facilitate interpolation of the data at different experimental conditions. Equations of state that are suitable for reservoir simulations are used to model the reported data. These models include the Peng-Robinson equation of state (PREoS), a volume-translated PREoS fit to high temperature, high pressure (HTHP) pure component density data, the PC-SAFT EoS, and modifications of the PC-SAFT EoS developed for better representation of HTHP data. The models give superior density predictions for (C 3 + C 10 ) mixtures compared to (C 3 + C 20 ) mixtures.

“…Two slightly different high-pressure view cells are used in this study and have been described in detail elsewhere [8,9,[14][15][16]. The only difference between the cells is that the sapphire window on one cell is sealed with an elastomeric o-ring whereas the other cell uses a window holder that eliminates the need for the o-ring.…”

“…The present study reports experimental high-temperature, high-pressure Krytox ® GPL 102 density to temperatures of 533 K and pressures of 275 MPa. The density data are obtained using a variable-volume, high-pressure cell previously used to obtain density data for n-alkanes from pentane to eicosane [13,14].…”

“…In addition, the PC-SAFT equation provides superior phase equilibrium predictions for mixtures with both associating and non-associating substances [20,21,22]. The PC-SAFT equation has recently been used to accurately predict the pure component densities of toluene, n-pentane, n-octane, isooctane, cyclooctane, n-decane, nhexadecane, n-octadecane, and n-eicosane [13,23]. However, for n-alkanes, PC-SAFT has the tendency to over-predict density values at pressures greater than ~ 55 MPa.…”

“…In this project we derive a new set of pure-component PC-SAFT parameters by fitting the equation to high temperature, high pressure (HTHP) density data present in the literature [13,23,55,65,66] that covers almost the entire pressure and temperature ranges of interest for deep reservoirs. Sub-critical density data are not used to obtain these new parameters.…”

Cover Illustration:The image provides an inside view of the density cell, which is capable of getting density data at 500°F and 35,000 psi. The left side image shows the bubble point of the gas. The tiny bubbles can be seen at the top center of the cell. The middle image shows the liquid-liquid-gas equilibrium phase exhibiting two liquid phases at the bottom and in the middle sections as well as a gas phase at the top. The right side image shows the solid formation as the pressure is increased.
