Mechanisms of Stabilization of Water-in-Crude Oil Emulsions
TL;DR: In this paper, the radial distribution function and the pair potential of water-in-crude oil emulsions have been measured using optical imaging technique, showing that non-DLVO forces such as attractive depletion and repulsive structural forces exist between the droplets.
Study of crude oil emulsion breaking via ultrasound
TL;DR: In this article, the influence of some controllable factors (ultrasonic intensity, treating time, sedimentation time, demulsifier amount and temperature) on crude oil emulsion breaking via ultrasound was discussed Mathematical models were set up by dimensional analysis method.
