The invention relates to a process and a product for the preparation of viscous hydrocarbon emulsions in water; it extends to these emulsions. The problem to be solved consists in favoring the use of viscous hydrocarbons. The process is characterized in that a first hydrocarbon-in-water emulsion 12, 14, 16, 18 is formed using an emulsifier, this emulsion 20 is degassed, the difference in phase density is adjusted, and The emulsion 22 is flocculated, the separated hydrocarbon-based material is recovered, it is re-emulsified 24 and it is packaged for final use 26, 28. The invention is applicable in particular for the combustion of emulsions. |
