Demulsification of water-in-crude oil emulsions via microwave heating technology

The traditional ways of breaking emulsions using heat and chemicals are disadvantageous from both economic and environmental perspectives. In this study, an alternative and cost effective technology for high frequency energy separation of oil emulsions has developed. The potentials of microwave tech...
