Abstract
Stable
concentrated oil-in-water (O/W) emulsions were prepared and their application
for heavy oil pipeline transportation was investigated using very viscous
Malaysian heavy crude oil. Two Malaysian heavy crude oil samples, Tapis and a
blend of Tapis and Masilla, were used to produce heavy crude oil-in-water
emulsions. The diverse factors affecting the properties and stability of
emulsions were investigated.
The study revealed that the stability of the oil-in-water emulsion
stabilized by Triton X-100 increases as the surfactant concentration increases,
with a subsequent decrease in the crude oil-water interfacial tension (IFT).
Increasing the oil content, the speed and duration of mixing, the salt
concentration and the pH of the aqueous phase of the emulsion; resulted in
increased emulsion stability, while increases in the temperature of the
homogenization process substantially reduced the viscosity of the prepared
emulsions.
