Asphaltene Precipitation in Crude Oils : Theory and Experiments

  title={Asphaltene Precipitation in Crude Oils : Theory and Experiments},
  author={Eduardo Buenrostro-Gonzalez and Carlos Lira-Galeana and Alejandro Gil-Villegas and Jianzhong Wu},
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 study for these systems was performed using the statistical association fluid theory for potentials… CONTINUE READING
