The formulation of emulsions in biodiesel production : emulsion stability and demulsification via micromave heating

In production of biodiesel, emulsions resulted from washing process is important as a method to remove sediment contaminant or by-product. Ironically, there have been a few cases when oil becomes a stable emulsion during water washing process. These situations normally cause by an aggressive washing...

Demulsification by using microwave is primarily due to heat temperature; therefore as the rate power output of microwave oven is increase, the temperature will increase and this lead to fast separation of water from emulsions.
