Solvent deasphalting (SDA) of heavy oil generally uses alkanes, from propane to heptane. The solvent power of propane is the weakest, and that of heptane is the strongest. Ethyl ether has slightly str...
This paper introduces a new comprehensive model for description of asphaltene deposition behavior in wellstring. The mechanisms of asphaltene deposition have been investigated experimentally using an ...
The nature of aggregation kinetics of colloidal asphaltene particles in mixture of toluene and heptane was investigated by utilizing a polarizing microscope with appropriate magnification. The concent...
Prediction of the effects of asphaltene deposition on oil reservoir parameters during water flooding was investigated in two scenarios of oil production wells with controlled oil rate and controlled ...
In this study a simple and applicable scaling equation as a function of pressure, molecular weight, dilution ratio (solvent) and weight percent of precipitated asphaltene has been developed. This equ...
Asphaltene precipitation is frequently the cause of increased cost of oil production in the petroleum industry. To avoid or minimize problems due to asphaltene precipitation, a model to predict the a...
(HDS) of atmospheric residue (AR) over Ni-Co-Mo catalysts supported on γ-alumina was carried out to examine the effect of alumina pore size on HDS activity, hydrodemetallization (HDM) activity and ini...
The effect of asphaltene (ASP) decomposition on catalyst deactivation under deep desulfurization conditions was investigated by reduction of sulfur from 0.3 to 0.1 mass% in a treated atmospheric resi...
