Measurement of the PVTx properties of n-heptane in supercritical water

pVTx Properties of Hydrothermal Systems

“…Panayiotou (2003) and Panayiotou et al (2007) developed quasi-chemical hydrogen bonding EOS for two supercritical binary aqueous methane and n-pentane mixtures. Excellent agreement was found between the predictions and measured by Abdulagatov et al (1996a) pVTx properties for H 2 O + CH 4 and H 2 O + n-C 5 H 12 (see Figure 2.9).…”

“…Abdulagatov reported density measurement uncertainty around 0.1% in the temperature range 523-673 K and pressures up to 100 MPa (Abdulagatov et al, 1996a) using this type of piezometer. Errors ranging between ±0.2% and ±0.7% were reported by some authors (Shmulovich et al, 1979) at 450-500 MPa using similar apparatuses.…”

“…Experimental molar volumes of supercritical mixtures(Abdulagatov et al, 1996a) as a function of pressure, at different mol fraction of the hydrocarbon, together with values calculated from quasi-chemical hydrogen-bonding model (solid lines) byPan- ayiotou (2003).…”

(p,v,T,x) Measurements of {(1−x)H2O+xC2H5OH} mixtures in the near-critical and supercritical regions

“…Our (p, v, T, x) apparatus has been described in detail previously [38][39][40][41][42][43][44][45][46][47][48][49]. The apparatus previously was used to measure (p, v, T) properties pure methanol [50] and (H 2 O + CH 3 OH) mixtures [39] in the near-critical and supercritical regions.…”
