Abstract: Asphalt-resin-paraffin accumulations are one of the most important problems of oil industry. Therefore prevention of asphalten deposition and effective control of accumulations require the analysis of their phase behavior. Current studies show that entropy interactions are of great importance in the process of asphalten aggregation. The depletion potential is one of the attracting forces of entropy nature. The work considers the concept of asphalten aggregation mechanism. The potential of depletion between asphalten nano-aggregates is evaluated.
