The emulsions are formed during the production of crude oil, which is often accompanied by water. These emulsions are undesirable and should treat to remove the dispersed water and accompanying inorganic salts. so, many researchers have over the years focused to probe of the appropriate demulsification techniques in the petroleum sector in order to meet production and transportation requirements, and to reduce corrosion and catalyst poisoning and to maximize the overall profitability of the crude oil production. Therefore, this study presents an overview of the emulsions, formation, classification, Stability, and properties. practical demulsification techniques in the petroleum sector, including chemical, microwave irradiation, biological, thermal, membrane, electrical, and ultrasonic techniques for both oilfield and synthetic emulsions. Amongst these techniques, chemical demulsification has been the most widely applied and reported in the literature. Moreover, a more effective demulsification process could be attained by leveraging synergistic effects by combining one or more of these techniques

In this study, the Sany-glass test was used to evaluate the performance of a new surfactant prepared from corn
oil as a demulsifier for crude oil emulsions. Central composite design (CCD), based on the response surface methodology
(RSM), was used to investigate the effect of four variables, including demulsifier dosage, water content, temperature, and
pH, on the efficiency of water removal from the emulsion. As well, analysis of variance was applied to examine the
precision of the CCD mathematical model. The results indicate that demulsifier dose and emulsion pH are two significant
parameters determining demulsification. The maximum separation efficiency of 96% was attained at an alkaline pH and
with 3500 ppm demulsifier. According to the RSM analysis, the optimal values for the input variables are 40% water
content, 3500 ppm demulsifier, 60 °C, and pH 8.
