Advances in molecular mechanisms,characterization,theoretical calculation and applications on asphaltenes aggregation
摘要
Abstract
The phenomenon of asphaltene association and aggregation in petroleum has an important impact on the exploitation,upgrading,storage and transportation of petroleum(especially unconventional petroleum ores such as heavy oil or tight oil reservoirs).The aggregation of asphaltene molecules directly determines the physical and interfacial properties of crude oil,which is the main cause of adsorption and deposition of petroleum components on the surface of minerals or pipeline walls,emulsification of oil and water(solid),and high viscosity of crude oil.This article systematically reviews the phenomenon and theoretical development of intermolecular association of asphaltene,explores the mechanism of asphaltene molecular association and aggregation from the perspective of non covalent interactions between molecules,and elaborates on the decisive influence of non covalent interactions dominated by electrostatic and dispersion on asphaltene association and aggregation.On this basis,the current status and development direction of the application of theoretical computation and interfacial characterization techniques on the study of asphaltene interfacial phenomena are summarized.Finally,based on the theory and phenomenon of asphaltene molecular association,the application of asphaltene association in the fields of solid surface adsorption and desorption,precipitation and dispersion,emulsion breaking technology development and viscosity reduction technology development has been discussed.关键词
