Abstract
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 and a chemical demulsifier through a mixing device having at least one flow restriction and recycling part of the mixture leaving the mixing device back to the device at or upstream of the restriction.
