Medium dependence of asphaltene agglomeration inhibitor efficiency [PDF]
Energy & Fuels vol.22, 2008, pp 1917 - 1922;, 2007 Applying chemical additives (molecule inhibitors or dispersants) is one of the common ways to control asphaltene agglomeration and precipitation. However, it is not clear why at some conditions the synthetic flocculation inhibitors as well as resins not only do not inhibit the asphaltene agglomeration,, they may also promote it, and why the increasing ...

A Numerical Simulation Study on the Kinetics of Asphaltene Particle Flocculation in a Two-dimensional Shear Flow [PDF]
Iranian Journal of Oil & Gas Science and Technology, 2019 In the current study, the kinetics of asphaltene particle flocculation is investigated under a shear flow through numerical simulation. The discrete element method (DEM) is coupled with computational fluid dynamics (CFD) to model the agglomeration and ...

Investigation into mechanisms and kinetics of asphaltene aggregation in toluene/n-hexane mixtures
Petroleum Science, 2019 Determining the rate of asphaltene particle growth is one of the main problems in modeling of asphaltene precipitation and deposition. In this paper, the kinetics of asphaltene aggregation under different precipitant concentrations have been studied. The

Asphaltene aggregation due to waterflooding (A molecular dynamics study) [PDF]
Yaseen, S. and Mansoori, G.A., 2018. Asphaltenes aggregation due
to waterflooding (A molecular dynamics simulation study). Journal of
Petroleum Science and Engineering, 2018 In the present study, we report our findings on various asphaltenes-water interactions at a high reservoir condition (550 K and 200 bar) and the role of water in asphaltene association during the waterflooding process. Molecular dynamics (MD) simulations are performed on oil/water and oil/brine systems. The oil phase is composed of asphaltenes (10 wt%)
