Review of Analytical Research of Influencing Factors of the Stability of Oil-in-water Emulsions
Pipeline transportation is one of the important ways of oil transportation,so the stability of heavy oil emulsion during transportation plays a decisive role in transportation efficiency.Different types of surfactants,interfacial tension,oil-water ratio,emulsification temperature,dispersed phase particle size,chemical additives,interfacial charge,etc.have different effects on the stability of heavy oil emulsion,and the main factors affecting the stability of oil-in-water emulsion are the size of the dispersible particle size,interfacial tension and the nature of oil-water interface film of heavy oil emulsion.In this paper,the effect of average particle size,interfacial tension and oil-water interface film properties on the stability of oil-in-water heavy oil emulsion was analyzed,the mechanism of stabilization was investigated as well as the factors affecting average particle size,interfacial tension and oil-water interface film properties,and the development prospect of oil-in-water emulsion stability research was analyzed.
