Affect of Viscosity and Droplet Diameter on water-in-oil (w/o) Emulsions: An Experimental Study
The influence of viscosity on droplet diameter for
water-in-crude oil (w/o) emulsion with two different ratios; 20-80 %
and 50-50 % w/o emulsion was examined in the Brookfield
Rotational Digital Rheometer. The emulsion was prepared with
sorbitan sesquiolate (Span 83) act as emulsifier at varied temperature
and stirring speed in rotation per minute (rpm). Results showed that
the viscosity of w/o emulsion was strongly augmented by increasing
volume of water and decreased the temperature. The changing of
viscosity also altered the droplet size distribution. Changing of
droplet diameter was depends on the viscosity and the behavior of
emulsion either Newtonian or non-Newtonian.
