Investigation of Asphaltene Stability in the Iranian Crude Oils
The influence of different factors on the asphaltene stability in three iranian crude oils was evaluated. Compositional studies ...
متن کاملAsphaltene nanoparticle aggregation in mixtures of incompatible crude oils.
We study the structure and phase behavior of asphaltenes comprised of large polyaromatic molecules in blends of naturally occurring crude oils using small angle neutron scattering (SANS). When two compatible oils are blended together, the asphaltenes remain dispersed as colloidal nanoparticles; however, when two incompatible oils are blended together, these asphaltene nanoparticles can aggregat...
متن کاملAsphaltene Precipitation in Crude Oils: Theory and Experiments
The precipitation of asphaltenes in two Mexican crude oils was measured using a combination of high-pressure isothermal expansion and atmospheric titration with nalkanes. Experiments were carried out from the liveand tank-oil type of samples of the same crude oils. For the oils investigated, compositional data, precipitation phase diagrams, and bubble point pressures are reported. A theoretical...
متن کاملFouling of Some Canadian Crude Oils
A thermal fouling study was undertaken using three sour Canadian crude oils. Experiments were carried out in a recirculation fouling loop, equipped with an annular (HTRI) electrically heated probe. Fluids at pressures of about 10001340 kPa under a nitrogen atmosphere were re-circulated at a velocity of 0.75 m/s for periods of 48 hours, and the decline in heat transfer coefficient followed under...
متن کاملInfluence of Asphaltene Aggregation and Pressure on Crude Oil Emulsion Stability
My supervisor introduced me to the field of surface and colloid chemistry in 1997, while studying physical chemistry as an undergraduate student at the University of Bergen. Little did I then know that the work would lead me into the petroleum industry, and a struggle with "the good and the bad asphaltenes". As an experimentalist, the work in the laboratory has, more often than not, provided re...
