| Abstract | Solubilities for 13 gases and vapours (CO2, alkanes from ethane to n-octane, benzene, toluene, xylene, dichloromethane, and methanol) in two Alberta bitumens (Athabasca and Wolf Lake) have been measured at several temperatures (30-150-degrees-C), using gas-liquid chromatography (GLC). The GLC method yields accurate solubilities and Henry's law constants for moderately soluble gases, but is not applicable to less soluble gases such as CH4 and H-2. Results have been used for calculations of DELTA-H(o) and DELTA-C(p)o for processes of the type Solute Substance (gas) reversible Solute Substance (in bitumen). Correlations of Henry's law constants and DELTA-H(o) values with carbon number for alkanes have been observed and used for predictions of CH4 solubilities in bitumens. |
