“…One method of using FeSO 4 ·7H 2 O from TiO 2 production is to obtain magnetite useful in steelmaking. Synthesis methods can be co-precipitation, obtaining microemulsions, sol-gel syntheses, and hydrothermal or solvothermal reactions [ 87 , 88 , 89 , 90 , 91 ]. The cheapest and easiest method of obtaining it is the co-precipitation of Fe 2+ /Fe 3+ ions (molar ratio 1:2) with sodium hydroxide or ammonia solution [ 92 , 93 , 94 ], followed by magnetic separation of the formed product [ 95 ].…”

Ferrous waste by-products from the metallurgical industry have a high potential for valorization in the context of the circular economy, and can be converted to value-added products used in environmental remediation. This research reviews the latest data available in the literature with a focus on: (i) sources from which these types of iron-based wastes originate; (ii) the types of ferrous compounds that result from different industries; (iii) the different methods (with respect to the circular economy) used to convert them into products applied in water and wastewater decontamination; (iv) the harmful effects ferrous wastes can have on the environment and human health; and (v) the future perspectives for these types of waste.

“…The existing demulsification methods include thermal convection, mechanical demulsification, biological technology, membrane demulsification, and chemical demulsification . However, due to issues such as technical operation, high cost, and low efficiency, these methods have obvious shortcomings, and chemical demulsification is currently the most widely used technology. , This method obtains the required interfacial activity by adjusting and controlling the performance of the demulsifier, in order to achieve the demulsification effect .…”

Demulsification of crude oil emulsion is an obvious problem in the whole of petroleum engineering, which needs to be dealt with urgently. In this paper, a supramolecular material Cucurbit[7]uril-SiO 2 (CB-SiO 2 ) synthesized with excellent demulsification efficiency (DE) on O/W emulsion was synthesized by a simple thermal synthesis method. The microscopic morphology and structure were investigated through modern characterization techniques. Furthermore, its stability, dynamic interfacial tension (IFT), and wettability (three-phase contact angle (CA)) were systematically investigated, and the demulsification efficiency of different conditions on crude oil emulsion was also investigated. Reassuringly, these results showed that when the temperature was 70 °C, the demulsification dosage was close to 600 mg/L and remained unchanged for 90 min; the demulsification efficiency is 2.2 times compared with the unmodified material, up to 93.63%. In addition, a plausible demulsification mechanism was proposed, which is that CB-SiO 2 can adsorb and disrupt the oil−water interface, leading to oil− water separation and promoting demulsification. It is a promising demulsification material for the oil industry demulsification.

“…Even though the energy resource revolution has become more common these days, the use of crude oil, as a well-known energy resource, ranks as one of the most significant. The formation of water-in-crude oil (W/O) emulsion resulting from well-production is one of the major obstacles in the petroleum industry 1 , 2 . Crude oil involving water as an impurity surrounded by indigenous oil surfactants, especially asphaltene (ASP) molecule, takes its toll on transportation, corrosion 3 , storage, and catalyst poisoning 4 .…”

The water droplets surrounded by a rigid interfacial asphaltene (ASP) film is one of the major setbacks in the petroleum industry. In this study, the properties of the interfacial ASP films around water droplets exposed to ionic surfactants as demulsifier were investigated. According to molecular dynamics (MD) simulation, the anionic surfactants are more effective than the cationic surfactant in the demulsification process since the anionic surfactants have the exact desire to localize not only near the ASP molecules but also near the water molecules. It has been found that it is likely to cause film changes and ruptures. Also, the MD simulation results for the desired surfactant, anionic surfactant, demonstrated that an increase in the surfactant concentration had an adverse effect on the system by hindering the change in the interfacial film. The increase in the temperature along with the enhancement in the adsorption rate of the surfactant results in the better performance of the demulsifier. Taking the MD and quantum results into account, the film deformation is a decisive factor in demulsification. The quantum computation has indicated that the electrostatic interactions play a significant role in selecting the attraction position and adsorption energy of the surfactant molecules.
