What is the viscosity of heavy oil?
Although variously defined, the upper limit for heavy oil is 22° API gravity with a viscosity of 100 cp (centipoise).
What is the viscosity of emulsion?
The viscosity of an emulsion depends on the initial viscosity of the bulk phase, η 0 and the volume fraction of the drops, φ. Many equations are used to describe this dependence and three are shown here. The Einstein equation obviously is the standard for solid particles.
What increases the viscosity of emulsion?
The viscosity of the continuous phase is increased by solution of stabilizers in the continuous phase of oil-in-water (o/w) emulsions. Mobility of the droplets and their collision frequency decreases. Thus, stabilizers can improve the stability of emulsions by hydrodynamic effects.
What are heavy oils used for?
It is used for the large ship engines of cargo vessels, bulk carriers of industrial or mining products like iron ore, cruise ships, and even the engine fuel for large oil tankers (though the oil that large oil tankers carry is called Crude Oil that has not yet been refined and is lighter than Heavy Fuel Oil).
How can the viscosity of emulsion be reduced?
Heavy oil emulsified viscosity reduction is to mix a certain concentration of surfactant solution with heavy oil at a certain temperature, making the high viscosity heavy oil is dispersed in the active water as oil droplets to form low viscosity O/W emulsion.
How does viscosity affect emulsion?
The results shows that viscosities of the light oil and its emulsions decrease as temperature increases because at higher temperature, oil and emulsion molecules obtain higher energy from heat thus making them less viscous and oil can flow easily [7].
How can you reduce emulsion?
The simplest way to prevent the formation of an emulsion is to gently swirl instead of shake the separatory funnel. By swirling the separatory funnel the agitation that can cause the emulsion to form is reduced, but the surface area of contact between the two phases is maintained to allow for extraction to occur.
Which of the following is heavy oil?
Petroleum geologists categorize bitumen from oil sands as ‘extra-heavy oil’ due to its density of less than 10° API. Bitumen is the heaviest, thickest form of petroleum.
