“…Furthermore, the results obtained in this study indicated a novel application potential of ILs as emulsifiers. However, not all ILs seem to be great emulsifier candidates, , despite having great surfactant ability. Considering the systems here studied, the right choice of IL precursor seems to play an important role in the emulsion formation and stabilization.…”

“…Otherwise, the emulsifier potential of ILs can be seen for imidazolium- and phosphonium-based ILs with long alkyl chain length that were used in emulsion systems to enhance lipase activity, which resulted in positive effects by improving emulsion stability . Recently, the emulsifier and demulsifier potential of imidazolium-based ILs for the petroleum industry have been reported, and commercial interest in such promising applications is increasing. On the other hand, the application of ILs in the agri-food industry is still scarce and mainly focused on extraction processes and analysis of bioactive compounds. , One of the main reasons is the divergence in literature regarding the toxicity of most common ILs, such as imidazolium-, phosphonium-, and pyridinium-based ILs .…”

We present a strategy to obtain highly stable emulsions with improved shelf life using ionic liquid (IL) technology, as exemplified by ILs obtained from fatty acids and choline. ILs presented high emulsifier ability affording emulsions with kinetic stability between 4 and 12 months. ILs also presented antimicrobial effectiveness against fungal and bacterial strains, while acting as emulsifiers at low concentrations. Through this approach, ILs derived from suitable compounds obtained from natural sources may have synergetic application potential as emulsifiers and antimicrobial preservatives, envisioning sustainable emulsion-based products and processes for the agri-food, cosmetic, and pharmaceutical industries.

“…Adewunmi and Kamal (39) presented studies of demulsifiers based on phosphonium-type ionic liquids with anionic components (including chloride, decanoate, and dicyanamide ions). In addition, imidazole-based ionic liquids (40), quaternary ammonium compound salts (Nalkyltriethylammonium bromide), and others can be used as demulsifiers (41). Among biodemulsifiers, such substances as ethyl cellulose, ethoxylated cocoamine, and α-amylase are considered (33).…”

Oil-water emulsion causes a wide range of problems, one of which is the emergence of significant decreases in pressure in flow lines resulting in higher pumping and transportation costs. The most widely developed trend among oil/water separation technologies is using demulsifiers based on magnetic nanoparticles (MNPs). MNPs have specific chemical and mechanical properties, providing unique opportunities to solve oil production issues. The key features of such magnetic nanoparticles for their sustainable application are their reusability and stability; the opportunity of remote manipulation using external magnetic fields gives them a singular benefit in transport operations. The main objective of the study is the systematization of MNPs researches for effective oil and water emulsion separation. This review provides MNP demulsifier characteristics, Oil-water emulsions (OWE) separation mechanism, and factors influencing oil-water emulsions efficiency disruption by MNP demulsifier. The relevance of this study is that oil-water emulsions are often encountered in practice during field development. To solve this problem, the use of demulsifiers based on magnetic nanoparticles is proposed. The novelty of the work lies in the fact that the work collects several factors affecting demulsification at once and describes the impact of each factor. Among these factors, the most influential are: emulsion characteristics, water salinity, pH, reservoir temperature, addition of chemical surfactants, time and magnetic field. The mechanism of formation of oil-water emulsions of various types is also described, and negative consequences of emulsion formation are discussed. The results showed that the magnetic nanoparticles need a protective layer and the demulsifier should have good wettability by the continuous phase of the emulsion.

“…Among these methods, chemical demulsification is widely applied owing to the tunable structure of demulsifier, high efficiency, and convenient operation [ 21 ]. Various chemical demulsifiers have been developed in last few decades, such as block copolymer [ 22 ], polysiloxane [ 23 ], hyperbranched polymer [ 24 ], dendrimer [ 25 ], and ionic liquids [ 26 ]. Chemical demulsifiers are widely used to break water-in-oil emulsions during the early stage of oilfield development.…”

Various nanoparticles have been applied as chemical demulsifiers to separate the crude-oil-in-water emulsion in the petroleum industry, including graphene oxide (GO). In this study, the Janus amphiphilic graphene oxide (JGO) was prepared by asymmetrical chemical modification on one side of the GO surface with n-octylamine. The JGO structure was verified by Fourier-transform infrared spectra (FTIR), transmission electron microscopy (TEM), and contact angle measurements. Compared with GO, JGO showed a superior ability to break the heavy oil-in-water emulsion with a demulsification efficiency reaching up to 98.25% at the optimal concentration (40 mg/L). The effects of pH and temperature on the JGO’s demulsification efficiency were also investigated. Based on the results of interfacial dilatational rheology measurement and molecular dynamic simulation, it was speculated that the intensive interaction between JGO and asphaltenes should be responsible for the excellent demulsification performance of JGO. This work not only provided a potential high-performance demulsifier for the separation of crude-oil-in-water emulsion, but also proposed novel insights to the mechanism of GO-based demulsifiers.
