摘要

Heavy crude oil is a kind of complex fluid, which possesses a similar density with water and extremely viscous, can cause a variety of difficulties during oil production, separation, transportation and refining [1,2].The viscosity of heavy oils at room temperature varies from 100 mPa·s to over 1000 Pa·s. Generally, only crude oil with viscosity lower than 400 mPa·s is suitable for pipeline transportation [3,4,5]. Therefore, various methods are tried to reduce the viscosity of heavy oils for pipeline transportation. For instance, dilution with lighter crudes or alcohols, heating, and the use of surfactants to stabilize emulsions are some of those common methods. However, the principle drawback of pipelines heating method is the high capital and operational costs [6]. Until now, light oil is becoming increasingly scarce. Moreover, chemicals as diluents such as kerosene and naphtha are expensive, so the emulsification of heavy oil is a desirable and necessary method for oil transportation.
