METHOD FOR HANDLING VISCOUS LIQUID CRUDE HYDROCARBONS |
摘要 |
A method for handling viscous liquid crude hydrocarbons is disclosed. The method involves (a) obtaining an emulsion comprising an aqueous fraction and a liquid crude hydrocarbon fraction, wherein the liquid crude hydrocarbon fraction has a first viscosity and contains an oil-soluble compound that reversibly converts to a surfactant under basic conditions, and further wherein the emulsion has a second viscosity that is less than the first viscosity of the liquid crude hydrocarbon fraction; and (b) breaking the emulsion by contacting the emulsion with a carbon dioxide-containing material to convert at least a portion of the surfactant to the oil-soluble compound. |
