The Influence of Process Parameters on Stability Of Water-In-Crude Oil Emulsion Stabilized by Span 80

There is a wide range of scientific literature related to emulsion stability, most of them dealt with water-in-oil (W/O) or oil-in-water (O/W) type. The present work is aimed to investigate the stability mechanisms of water-in-crude oil emulsion stabilized by a non-ionic emulsifier (Span 80). The bl...
