“…However, there is a need to develop new and cost-effective technologies because some of the previously mentioned methods do not have good perdurability, they are expensive, or environmentally harmful (Escojido et al, 1991;Jamaluddin et al, 1996). In this order, and due to its exceptional properties, nanoparticles have taken particular interest in the oil industry in stages such as exploration, drilling, EOR methods, refinery processes, water treatment, and crude oil transportation, among others (Ali et al, 2015;Bennetzen and Mogensen, 2014;Betancur et al, 2014;Franco et al, 2013aFranco et al, , 2014Franco et al, , 2016Giraldo et al, 2013a;Guo et al, 2015;Hashemi et al, 2014;Riaza et al, 2014). Nanoparticles have different morphologies such as spherical, tubular, or irregular shape and are characterized by having a small size between 1 and 100 nm with a high ratio of surface area/volume, high dispersibility, and selectivity to capture high molecular weight compounds such as crude oil asphaltenes (Franco et al, 2013b;Lo¨vestam et al, 2010).…”

The main objective of this work is to synthesize and evaluate magnetite (Fe 3 O 4) nanoparticlebased ferrofluids for reducing the viscosity of an extra heavy crude oil. The carrier fluid of the nanoparticles was synthesized using an engine lubricant recycled from the automotive industry and hexadecyltrimethylammonium bromide as a surfactant. Fe 3 O 4 nanoparticles were synthesized by coprecipitation method. The effect of the concentration of nanoparticles in the viscosity reduction degree was determined for dosages between 0 and 50,000 mg/L. Different dosages of carrier fluid were evaluated between 0 and 10% v/v. The effects of the amount of brine emulsified, temperature, time, and shear rate were assessed. Overall, the results showed that viscosity and shear stress of extra heavy crude oil could be reduced up to 81 and 78% in the presence of ferrofluid, respectively. The rheological behavior of extra heavy crude oil in the presence and absence of ferrofluid was assessed by Cross, Ostwald-de Waele, and Herschel-Bulkley models.

“…In other words, the siloxane hydrophobes differ considerably from the traditional block organic polymers due to their weak intermolecular attractive forces. Structurally, they are characterized by (Abdel‐Raouf et al, ) SiOSi bond angles that are larger than COC bond angles (Adilbekova et al, ), SiO bond lengths that are longer than COC or CC bonds, (Ali et al, ) a greater freedom of rotation around the SiO bond compared to the CC bond, and (Ali et al, ) freely rotating methyl groups that can orient toward interfaces and also result in “free” volume for the siloxane hydrophobic chains (Eduok et al, ; Liu, ; Somasundaran et al, ). Therefore, all these characteristics give siloxane hydrophobes their comb‐like shape for diffusing easily in the crude oil.…”

The principle focus of this work is to address the issues associated with the existence of water in crude oil, especially corrosion, scaling, viscosity, and catalyst suppression problems. This work aims to prepare star polymer nonionic surfactants based on (2Z,2′Z,2″Z)‐4,4′,4″‐((nitrilotris(ethane‐2,1‐diyl))tris(oxy))tris(4‐oxobut‐2‐enoic acid) to be used as demulsifiers. To achieve this aim, maleic anhydride was reacted with triethanolamine followed by esterification with the polyethylene oxide polypropylene oxide copolymer (PPO‐PEO 5000) and silicone polyether (ABIL B 8843). The chemical structure of the prepared compounds was assessed using gel permeation chromatography (GPC), Fourier transform infrared (FT‐IR), and 1H NMR. Demulsifier performance was determined by quantifying surface tension (ST), dynamic interfacial tension and interfacial rheology, partition coefficient (PC), and relative solubility number (RSN). The efficacy of the prepared emulsion breakers on asphaltenic crude oil emulsion was examined using the bottle test. The research results demonstrated that the prepared breaker based on the silicone polymer was more efficient in breaking the asphaltenic crude oil emulsion than a block copolymer and EO/PO‐based copolymers at 1500 ppm and after 120 min.

“…Several techniques for crude oil demulsification have been reported in the literature [23][24][25], and they can be grouped into three broad categories, namely, chemical, physical (mechanical, thermal or microwave, electrical, ultrasonic, and membrane), and biological [19]. Amongst these techniques, chemical demulsification has been the most widely applied and reported in the literature, which involves the addition of demulsifier to crude oil emulsions [26][27][28]. The main function of the chemical additives is to destabilize the emulsifying agents [5].…”

An Overview of Recent Advances in State-of-the-Art Techniques in 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.
