Optimization of separation of oil from oil-in-water emulsion by demulsification using different demulsifiers

Separation of oil from oil-in-water emulsion is a major challenge in petroleum industries during the producing and refining process. The authors investigated characterization of oil-in-water emulsion and subsequently separation of oil from emulsion using different chemical dimulsifiers. The effect of settling time, pH, temperature, and demulsifier dosage on oil separation efficiency has been studied. It was observed that as time, temperature,...
