METHOD FOR TREATING WATER-IN-OIL EMULSION

PROBLEM TO BE SOLVED: To provide a method for treating a water-in-oil emulsion, in which an oil phase is separated effectively from a water phase and simultaneously energy consumption is made low. SOLUTION: The method for treating the water-in-oil (W/O) emulsion comprises a step of adding, under hea...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for treating a water-in-oil emulsion, in which an oil phase is separated effectively from a water phase and simultaneously energy consumption is made low. SOLUTION: The method for treating the water-in-oil (W/O) emulsion comprises a step of adding, under heating, an ionic liquid to the W/O emulsion, which contains water of 0.5-85 vol.% as a disperse phase, to the extent that the concentration of the ionic liquid in the W/O emulsion becomes within 0.01-100 μL/g. The ionic liquid to be used is the salt which is in a liquid state at the temperature of
