“…The time dependent water droplet diameters are summarized in Table 2 . It clearly indicates that water droplets coalesce and their diameters expand about 14.0% to 32.0% within 20 min, consistent with the literatures [23] , [24] . After ultrasonic irradiation time of 60 min, tiny water droplets coalesced would reach a maximum expansion of 87%.…”

“…The droplets of different particle sizes vibrate at different velocities, increasing the probability of their collision and coalescence, thus facilitating oil–water separation [78] . Acoustic cavitation results in secondary emulsification, which reduces the demulsification efficiency [69] . However, Antes et al [71] showed that mechanical effects of acoustic cavitation can break the barrier between droplets and facilitate their coalescence.…”

“…The effect of parameters such as the irradiation input power, irradiation time, temperature, and injected water on the demulsification efficiency was investigated by Check and Mowla [144]. The interaction between the parameters resulted in the highest demulsification efficiency (99.8%) at an optimum input power of 57.7 W, irradiation time of 6.2 min, and temperature of 100 • C. A further investigation [145] focused on the effects of two ultrasonic irradiations, namely, primary and secondary, for the demulsification of crude oil emulsion. The findings showed that the settling time decreased at an irradiation power of 75 W for primary irradiation and 50 W for secondary irradiation at an irradiation time of 45 s. There is a growing interest in the application of low-frequency ultrasound for the demulsification of crude oil emulsions.…”

The processing of crude oil often requires the extraction of a large amount of water. Frequently, crude oil is mixed with water to form water-in-crude oil emulsions as the result of factors such as high shear at the production wellhead and surface-active substances that are naturally present in crude oil. These emulsions are undesirable and require demulsification to remove the dispersed water and associated inorganic salts in order to meet production and transportation specifications. Additionally, the demulsification of these crude oil emulsions mitigates corrosion and catalyst poisoning and invariably maximizes the overall profitability of crude oil production. Recently, there has been growing research interest in developing workable solutions to the difficulties associated with transporting and refining crude oil emulsions and the restrictions on produced water discharge. Therefore, this paper reviews the recent research efforts on state-of-the-art demulsification techniques. First, an overview of crude oil emulsion types, formation, and stability is presented. Then, the parameters and mechanisms of emulsification formation and different demulsification techniques are extensively examined. It is worth noting that the efficiency of each of these techniques is dependent on the operating parameters and their interplay. Moreover, a more effective demulsification process could be attained by leveraging synergistic effects by combining one or more of these techniques. Finally, this literature review then culminates with propositions for future research. Therefore, the findings of this study can help for a better understanding of the formation and mechanisms of the various demulsification methods of crude oil to work on the development of green demulsifiers by different sources.
