in this investigation, the mechanical properties of the blends of blown bitumen110/10, heavy vacuum slops (h.v.s), bitumen 60/70 penetration grade and isotactic polypropylene (ipp) were studied for the first time. our results showed that modulus varies non-linearly and at certain asphaltenes contents a peak appears. considering these phenomena it is revealed that in the absence of ipp, interact...

Abstract Carbonate acidization is the process of creating wormholes by injecting acid to increase reservoir permeability and oil production. Nevertheless, some oils are problematic with low asphaltene stability, which affects wormholing process. The interactions between acid, rock, lead acid-asphaltene sludge formation, reduces productivity injectivity. Neglecting this formation leads over pred...

Paraffinic froth treatment (PFT) is an essential step in oilsands extraction. The ability to quantitatively understand and control asphaltene precipitation induced by solvent dilution key technology innovation PFT process. In this work, we investigate the early stage of a model oil system response diffusive addition quasi-2D confinement. Using total internal reflection fluorescence microscope, ...

The aggregation behavior of asphaltene in the toluene-hexane mixture is systematically investigated using experimental techniques such as optical microscopy and Fourier-transform infrared spectroscopy (FTIR) combined with molecular dynamics (MD) simulations. images various concentrations are processed to determine size aggregates. FTIR performed within our work order understand formation aggreg...

In this paper, we present a systematic review of the perturbed-chain statistical associating fluid theory equation state (PC-SAFT) EoS for thermodynamic modeling with application in asphaltene phase behavior simulation. The SAFT and its modified version known as PC-SAFT is briefly introduced. Then, uses tool highlighted. Crude oil characterization methods procedures are described focus on SARA-...
