稀释诱导沥青质沉淀影响因素的研究进展

REVIEW OF INFLUENCING FACTORS OF DILUTION-INDUCED ASPHALTENE PRECIPITATION

稀释诱导沥青质沉淀能显著降低原油黏度,提升原油流动性。综述了有关沥青质研究的现状,并结合Smoluchowski聚集模型,对沥青质沉淀的影响因素进行了理论分析,结果表明沥青质沉淀受热力学因素和混合条件的影响。另外,介绍了微流体新技术,在此基础上,对进一步探究稀释诱导沥青质沉淀动力学进行了展望。

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.
