Oil-in-water emulsion technique enhancement for viscous crude oil flow in pipelines

The production of heavy crude oil is limited due to its high viscosity. It is expected to increase in the future as low viscosity crudes are depleted. The high viscosity lead to the increasing of pump energy as it creates high pressure drop. In order to reduce the viscosity of the heavy crude, it is...

O/W emulsions with three different ratios (50 - 50% and 65 - 35% and 80 - 20%) were prepared at a mixing speed of 2000 rpm with the concentrations of (1.0 wt%, 1.5 wt% and 2.0 wt%) of each emulsifier.
