Effect of drainage height on concentration-dependent propane dispersion in vapex
This article examines the effect of drainage height (i.e. height of saturated porous medium) on concentration-dependent dispersion coefficient of propane in vapour extraction (Vapex) of heavy oil. For this purpose, Vapex experiments are carried out at 21 degrees C using propane as a solvent at 0.689?MPa pressure for three different drainage heights of the heavy oil medium. Subsequently, the concentration-dependent dispersion coefficients of propane are determined. The results show that the dispersion coefficient of propane (at all concentrations) in heavy oil increases with the drainage height. (c) 2011 Canadian Society for Chemical Engineering
