About this document
Asphaltenes in Water-Crude Oil Emulsions by Daniel Felipe is a document available to read on EtoBox.
This document summarizes research into the role of asphaltenes in stabilizing water-in-crude oil emulsions. While asphaltenes were widely believed to be the main stabilizing agent, experiments showed they are only weakly surface active on their own. Studies found that there is a critical solvent-to-bitumen ratio above which emulsions flocculate and below which they are stable. Microinterferometric experiments demonstrated that thin oil films separating water droplets stopped draining at a thickness of aroun
