REVIEW OF INFLUENCING FACTORS OF DILUTION-INDUCED ASPHALTENE PRECIPITATION

Abstract

Abstract: Dilution-induced asphaltene precipitation can significantly reduce the viscosity of crude oil and improve the liquidity. This article reviewed the current research status of asphaltene and explained the influencing factors of asphaltene precipitation theoretically by Smoluchowski’s aggregation model. The results showed that asphaltene precipitation was affected by both thermodynamics and hydrodynamics factors. In addition, the new microfluidic technology was introduced, and on this basis, further research on the kinetics of dilution-induced asphaltene precipitation was prospected.

Key words: asphaltene precipitation, Smoluchowski’s aggregation model, microfluidic technology
