Abstract
A method of demulsifying an emulsion of oil and water whereby palm oil fuel ash, which is a low cost waster product obtained from oil palm processing, is added to the emulsion and the resulting mixture is agitated, thereby breaking the emulsion into an aqueous phase and an oil phase. Solid particles of palm oil fuel ash settle to the bottom of the aqueous phase, allowing easy separation of the oil phase, the aqueous phase, and the settled solid particles of palm oil fuel ash.
