Demulsifying water-in-oil emulsions

摘要

A method for continuously demulsifying a viscous, stable water-in-oil emulsion, which emulsion comprises from 50 to 80% water as the dispersed phase, comprises passing the emulsion from tank 4 and a chemical demulsifier from tank 8 through a mixing device 7 having at least one flow restriction 1 and recycling part of the mixture leaving the mixing device back to the device at or upstream of the restriction.
