A critical review of the development and demulsification processes applied for oil recovery from oil in water emulsions

Wamda Faisal et al.

Summary: This review introduces the application of chemical demulsifiers in the recovery of oil from water and water from oil. Different types of surfactants involved in emulsion formation and stability enhancement are discussed, and promising demulsifiers such as nanoparticles, hyperbranched polymers, and ionic liquids are explored. Functionalized magnetic nanoparticles and hyperbranched polymers achieve high oil recovery rates, while ionic liquids have limitations due to their high cost. Nanoparticles show excellent oil recovery behavior at low concentrations and ambient temperature.

Application of magnetic nanoparticles in demulsification: A review on synthesis, performance, recyclability, and challenges

Ahmad A. Adewunmi et al.

Summary: The use of magnetic nanoparticles (MNPs) as demulsifiers is growing rapidly due to their recyclability and high surface area. Factors such as dosage, pH, salinity, hydrophilicity, and shape play crucial roles in designing a successful demulsifier using MNPs. Regeneration and recyclability of MNPs after demulsification, as well as challenges and recommendations for their use in emulsions, are highlighted in this review.

Magnetically Recyclable Graphene Oxide Demulsifier Adapting Wide pH Conditions on Detachment of Oil in the Crude Oil-in-Water Emulsion

Haiyan Xu et al.

Summary: An amphiphilic and magnetically recyclable graphene oxide demulsifier was synthesized by grafting magnetic nanoparticles and ethylenediamine onto the GO surface, exhibiting favorable demulsification performance for crude oil-in-water emulsions under various pH conditions. The MR-GO can be reused multiple times with consistent high demulsification efficiency. Through a combination of interfacial adsorption interactions, electrostatic attraction, and external mechanical forces, the demulsifier disrupts and stabilizes the emulsion interface, facilitating the rapid gathering of oil droplets to accomplish demulsification.
