Phase equilibria of supercritical propane Fengcheng bitumen system and the density and viscosity of the liquid phase
Vapour-liquid equilibria of supercritical propane-Fengcheng bitumen system have been determined at 381.15 K, 388.15 K, and 398.15 K and at pressures ranging from 4.4 to 8.6 MPa. The densities of the two phases, the viscosity of the liquid phase, and the average molecular weight of the extracted bitumen components were also determined.
