Abstract
Aggregation of asphaltenes over time in the presence of dispersant S5A has been studied using photon correlation spectroscopy. The addition of the dispersant to toluene solutions of asphaltenes decreases the size of the aggregates, stabilizes their growth, and reduces the rate of aggregation for a considerably long time. The growth stabilization is achieved at the asphaltenes to dispersant ratio of 0.2–4.
