“…The presence of CH 3 groups connected to the quaternary ammonium [-(CH 3 ) 2 -N-(CH 2 ) 12 -N-(CH 3 ) 2 -] was evident from a singlet peak at δ 3.27 ppm [5]. The most intense peak at δ 3.65 ppm was attributed to the presence of the ethylene oxide chain (-O-CH 2 -CH 2 -O-CH 2 -CH 2 -) [31]. The singlet peak that appeared at δ 4.03 ppm was coupled 31.8 ppm related to the CH3 and CH2 groups constituting hydrophobic tail.…”

“…In addition, characteristic signals at δ 62.1 ppm and δ 64.5 ppm correspond to the two CH2 groups at the quaternary ammonium [-CH2-N-(CH3)2-CH2-(CH2)10-CH2-(CH3)2-N-CH2-] [38]. The most intense peak at δ 70.4 ppm was attributed to the presence of the ethylene oxide chain (-O-CH2-CH2-O-CH2-CH2-) [31]. Characteristic signals at δ 170.8 ppm could be attributed to the carbon of the amide group [-CH2-C=O-NH-CH2-].…”

Synthesis of Novel Ethoxylated Quaternary Ammonium Gemini Surfactants for Enhanced Oil Recovery Application

Two aspects are always considered in the design and development of new surfactants for oilfield application. One of them is that surfactant must be sufficiently stable at reservoir temperature and the other is the solubility of the surfactant in the injection water (usually seawater) and the formation brine. Most industrially applied surfactants undergo hydrolysis at elevated temperature and the presence of reservoir ions causes surfactant precipitation. In relevance to this, a novel series of quaternary ammonium gemini surfactants with different length of spacer group (C8, C10, and C12) was synthesized and characterized using FT-IR, 13C NMR, 1H NMR, and MALDI-TOF MS. The gemini surfactants were prepared by solvent-free amidation of glycolic acid ethoxylate lauryl ether with 3-(dimethylamino)-1-propylamine followed by reaction with dibromoalkane to obtain quaternary ammonium gemini surfactants. The gemini surfactants were examined by means of surface properties and thermal stabilities. The synthesized gemini surfactants showed excellent solubility in the formation brine, seawater, and deionized water without any precipitation for up to three months at 90 °C. Thermal gravimetric data revealed that all the gemini surfactants were decomposed above 227 °C, which is higher than the oilfield temperature (≥90 °C). The decrease in critical micelle concentration (CMC) and surface tension at CMC (γcmc) was detected by enhancing spacer length in the order C8 ˃ C10 ˃ C12 which suggested that the larger the spacer, the better the surface properties. Moreover, a further decrease in CMC and γcmc was noticed by enhancing temperature (30 °C ˃ 60 °C) and salinity (deionized water ˃ seawater). The current study provides a comprehensive investigation of quaternary ammonium gemini surfactants that can be further extended potentially to use as a suitable material for oilfield application.

“…Among these techniques, chemical means of separation have become one of the most common methods, where different polymers and copolymers are used to absorb, disperse or collect the spilled oil [ 5 , 6 , 7 ]. In addition to polymers, some ionic liquids, poly (ionic liquids) and surfactants have also been tested in recent years [ 8 , 9 , 10 , 11 ]. The removal of spilled oils by employing chemical collectors has become one of the most acceptable techniques because of its high efficiency and ability to reuse the chemicals as compared with other methods such as oil spill sorbents [ 9 , 12 , 13 ].…”

Green Synthesis of Hydrophobic Magnetite Nanoparticles Coated with Plant Extract and Their Application as Petroleum Oil Spill Collectors

et al. 2018

In this study, an easy, rapid and eco-friendly method was used successfully to synthesize the magnetite nanoparticles (MNPs). In order to fine-tune the synthesized MNPs for the collection of heavy crude oil spills, the particles’ surface was modified with green hydrophobic biocomponents that were extracted from Anthemis pseudocotula (AP). The surface modified reaction carried with that of the MNPs in the presence of n-hexane extract (APH) resulted in the formation of APH-MNPs, while in the presence of chloroform extract (APC), resulted in APC-MNPs formation. The as-formed MNPs were thoroughly characterized using transmittance electron microscopy, X-ray powder diffraction, vibrating sample magnetometer and thermogravimetric analysis. The efficiency of the surface-modified MNPs for the collection of oil spills in the presence of an external magnetic field was evaluated by taking different ratios of MNPs:crude oil. From the analysis of the results, we found that the APH-MNPs particles have higher efficiency in the collection of heavy crude oil than the corresponding APC-MNPs.

“…Recent investigations have found that hydrophobic surface-active ionic liquids can be used for effective demulsification of W/O emulsions in the oil and gas industries [ 24 , 93 ]. A research conducted by Hazrati et al [ 101 ] indicated that hydrophobic ionic liquids (e.g., C n mim PF 6 ) demulsified emulsions better than hydrophilic ionic liquids (e.g., C n mim Cl) [ 101 ].…”

“…They are associated with unique characteristics such as thermal stability, non-flammability, recyclability, and low vapor pressure [ 21 , 22 , 23 ]. These properties make ionic liquids a suitable substitute for organic solvents and commercial demulsifiers [ 23 , 24 ]. Ionic liquids have been used by different researchers to evaluate their efficiency in demulsification processes, mostly at the laboratory scales.…”

In recent years, ionic liquids have received increasing interests as an effective demulsifier due to their characteristics of non-flammability, thermal stability, recyclability, and low vapor pressure. In this study, emulsion formation and types, chemical demulsification system, the application of ionic liquids as a chemical demulsifier, and key factors affecting their performance were comprehensively reviewed. Future challenges and opportunities of ionic liquids application for chemical demulsification were also discussed. The review indicted that the demulsification performance was affected by the type, molecular weight, and concentration of ionic liquids. Moreover, other factors, including the salinity of aqueous phase, temperature, and oil types, could affect the demulsification process. It can be concluded that ionic liquids can be used as a suitable substitute for commercial demulsifiers, but future efforts should be required to develop non-toxic and less expensive ionic liquids with low viscosity, and the demulsification efficiency could be improved through the application of ionic liquids with other methods such as organic solvents.
