The Effects of Ultrasound on Heavy Oil Emulsion

Ultrasound would make change component of heavy oil,a certain degree of viscosity reduction of the role of heavy oil.In the absence of emulsifier present conditions,ultrasonic can make high water-cut W/O emulsion form O/W emulsion.The emulsion formed comparison adding emulsifiers transfer phase formation O/W emulsion,the stability was rather poor.Droplet size distribution broadens,but the main distribution range of the main narrow and droplet dispersion was better.While the power-law rheological fluid to follow the law,it was weakened by non-Newtonian behavior.From the micro-observation analysis,within the scope of this experimental study,after ultrasonic treatment,the high water-cut W/O emulsion formed O/W emulsion was not a strict sense of the emulsion.
