The Potential of Microwave Heating in Separating Water-in-Oil (w/o) Emulsions

With the increasing energy crisis and the drive to reduce CO2 emissions, the mechanism of microwave heating is essentially that of dielectric heating. In this study, microwave demulsification method was investigated in a 50-50% and 20-80% water-in-oil emulsions with microwave exposure time varied fr...
