The modified regular solution model was developed to predict onset and amount (yield) of asphaltene precipitation from mixtures of crude oil and solvents. The most recent version of the model inclu...

Abstract Visbroken products from a Western Canadian bitumen were generated at five different reaction conditions (temperature and residence time) in an in-house lab-scale continuous reactor unit. Visbroken products from a second Western Canadian bitumen and an Arabian vacuum bottoms were obtained from other sources. Densities and viscosities were measured for the whole oil, the maltenes, the distillates, the distillation residue, and the SARA (saturates, aromatics, resins and asphaltenes) cuts o...

The Modified Regular Solution (MRS) model is an activity coefficient approach previously developed to predict the onset and amount of asphaltene precipitation from n-paraffin diluted crude oils. The activity coefficients in this model are determined from an enthalpic contribution based on the Regular Solution theory and a Flory-Huggins (configurational) entropic contribution. The inputs are the molar volume and solubility parameter of the crude oil pseudo-components which are defined based on th...

One reason it is challenging to predict oil recovery rates from solvent-based heavy oil recovery methods is that the interplay of the mass transfer and convective flow mechanisms is not well unders...

The kinetics of asphaltene precipitation was investigated for five crude oils diluted with n-heptane at 21oC in air and nitrogen atmospheres. The onset of precipitation, defined as the precipitant (n-heptane) content at which detectable asphaltene particles first appear, was measured in air at different contact times using optical microscopy and a gravimetric method. Asphaltene yields (mass asphaltene / mass oil) were measured in air over time gravimetrically. The data were compared with yields ...
