Abstract
|
Chemical
control of asphaltene precipitation using dispersants and inhibitors of
precipitation or solvents of asphaltene is common. While asphaltene in crude
oil is stable under specific conditions, there is no assurance that the
system will be stable and asphaltenes could be remaining in suspension state.
Researchers studiued the kinetic effects of three dispersants on
stabilization of asphaltene aggregates using the turbidity measurement
method.
Turbidity measurement showed as the dispersant strength rises, the turbidity of unstable sample containing dispersant less declines versus time. In order to carry out further studies on dispersants, the effect of dispersant on asphaltene particle size distribution was investigated. The results of asphaltene particle size distribution measurements showed that adding dispersant cause to decrease the volume percent of particles with medium diameter. |
