Abstract
The method for forming a stable emulsion of a viscous crude hydrocarbon in an aqueous buffer solution, includes the steps of: providing a viscous crude hydrocarbon containing an inactive natural surfactant and having a salt content by weight of less than or equal to about 1.0% and having a total acid number of greater than or equal to about 1, preferably greater than or equal to about 2.5; forming a solution of a buffer additive in an aqueous solution to provide a basic aqueous buffer solution, the buffer additive being operative to extract and activate the inactive natural surfactant from the viscous crude hydrocarbon; and mixing the viscous crude hydrocarbon with the aqueous buffer solution at a rate sufficient to provide an emulsion of the viscous crude hydrocarbon in the aqueous buffer solution, whereby the buffer additive extracts the inactive natural surfactant from the viscous crude hydrocarbon and activates the inactive natural surfactant so as to stabilize the emulsion. The inactive natural surfactants are preferably carboxylic acids. The buffer additive is preferably selected from the group consisting of (a) sodium hydroxide in combination with sodium bicarbonate and (b) sodium silicate. A method for transporting the emulsion is also disclosed.
