Reduced viscosity heavy hydrocarbon composition in form of multiple emulsion and its production

摘要

Composition comprising heavy hydrocarbons and water, having a viscosity much lower than that of the hydrocarbons it contains. It is constituted by a multiple emulsion, the internal phase of which comprises a primary emulsion of water in the hydrocarbons and the external phase comprises water containing at least one surfactant, in which this primary emulsion is dispersed, thus forming a secondary emulsion which is self-stable or is stabilized by the addition of stabilizing agents to its external phase.
