“…Among the technologies used in EOR, the use of operations to reduce interfacial tension by surfactants is implemented worldwide (Austad and Taugbøl 1995;Al-Wahaibi et al 2014;Nabipour et al 2017;Marhaendrajana et al 2018), because its ability to reduce the interfacial tension between water and oil allows the oil trapped in the pores of the reservoir by capillary forces to be recovered (Van Dyke et al 1991;Pornsunthorntawee et al 2008;Li et al 2012;Guo et al 2015;Zhang et al 2015;Kumar and Mandal 2017). However, to achieve a satisfactory result, high concentrations of surfactants are required (Sabatini et al 2000;Fernandes et al 2016), which ultimately depends upon high costs for the use of chemical surfactants.…”

In this study, the biosurfactant produced by Pseudomonas aeruginosa was evaluated in view of its ability to be used in Microbial-Enhanced Oil Recovery (MEOR). This microorganism was isolated from a soil artificially contaminated with crude oil and used to produce rhamnolipid using glycerol as the carbon source. The biosurfactant efficiently reduced water surface tension from 72 to 35.26 mN/m at its critical micelle concentration of 127 mg/L and emulsification rate (E 24) of 69% for the crude oil. Furthermore, it was demonstrated that the rhamnolipid can recover oil, even 2 months after its production, which shows that its biodegradability is not a disadvantage to the application in MEOR. The best result, for a biosurfactant concentration of 100% above the Critical Micelle Concentration (CMC) and petroleum with API gravity of 21.90, showed that the total recovery factor was 50.45 ± 0.79%, of which 11.91 ± 0.39% corresponds to MEOR.

“…[1][2][3][4] However, most of the commercial synthetic surfactants have signicant detrimental effects on the environment, which has driven researchers to synthesize natural surfactants from renewable resources. [5][6][7] The focus on an eco-friendly environment concerns the use of surfactants and creates interest to develop a natural surfactant against commercial non-biodegradable surfactant.…”

“…According to the report, the presence of cations (e.g., Ca 2+ and Na + ) may shield the negative charges of surfactant movements, thus decreasing the repulsive force between drops [40]. At the same time, NaCl was beneficial to promote surface movements to transfer from the bulk solution to oil-water interface, compress the electrical double layer, and form a compact surfactant molecule arrangement on the interfacial layer [42]. Because of the interaction of the two effects, the interfacial tension increased first and then decreased with the increase of salt concentration.…”

“…The particle sizes in the KCl emulsion were the largest among the various salt emulsions (5 to 10 µm), with the majority of droplets having a size of approximately 8 µm. The effect of salt on the droplet size is attributed to the effect of charge screening [48] and cationic gelling agent [42]. The larger the viscosity of the continuous phase in the emulsion, the smaller the droplet agglomeration tendency, and the smaller the particle size, the more evenly dispersed it is in the emulsion network structure [45], which means that the stability of the emulsion is stronger.…”

The xylitol ester of hydrogenated rosin (XEHR) was obtained for the first time from biomass-based hydrogenated rosin and xylitol using an environmentally friendly, high-pressure CO2 catalytic synthesis. This compound is intended for use as an emulsifier for food. Analyses by ICP-AES showed the absence of heavy metal residues in the product, such that it met food standards. Fourier transform infrared and nuclear magnetic resonance spectroscopies together with gel permeation chromatography confirmed the successful esterification and the formation of a monoester and diester with molar masses of 427 and 772 g/mol. The emulsification of water/soybean oil mixtures by adding the XEHR was assessed at pH values of 4, 6.86, and 10 and in the presence of NaCl, KCl, MgCl2, and CaCl2. The XEHR was found to act as an emulsifier by reducing the interfacial tension of such mixtures to less than 2 mN/m under all conditions. The highest emulsifying activity index (9.52 m2/g) and emulsifying stability index (94.53%) were obtained after adding MgCl2 (100 mM). Particle size and confocal microscopy showed that the presence of salts gave a more uniform droplet size and a finer emulsion structure. The high viscosities of the emulsions containing salts also suggested a more cohesive oil droplet network.
