“…For solutions with NaCl and Na 2 SO 4 , the acidic strength of the anions is the controlling parameter for IFT reduction, where the higher the acidic strength of anions the higher the IFT values. This is the reason for having lower IFT values with NaCl rather than Na 2 SO 4 [23][24][25][26]. Figure 6 displays the IFT values between crude oil and various solutions that were prepared using the AS surfactant's CMC value and optimum value of alkaline.…”

In this investigation, a unique approach using a green surfactant extracted from the Avena sativa (AS) plant in conjunction with three different salts, including Na2CO3, NaCl, and Na2SO4, was examined for enhanced oil recovery. In addition, the efficiency of NaOH as a supplementary chemical in the process was investigated. Based on the results of the interfacial tension (IFT), the optimum value of NaOH was found to be 2,000 ppm, while the green surfactant had a CMC value of 4,000 ppm. The IFT value at the CMC point of NaOH was 2.34 mN/m, when the FB was used, and the IFT value was 2.78 mN/m, when deionized water was used. In addition, in terms of IFT reduction, wettability modification, and oil recovery factor enhancement, Na2CO3 was the most suitable salt with the AS surfactant at the CMC point (4,000 ppm), followed by NaCl and then Na2SO4. The IFT values at the optimum salinity point (10,000 ppm) of Na2SO4, NaCl, and Na2CO3 were 3.18, 3.05, and 2.87 mN/m, respectively. Moreover, the contact angles at the optimum salinity point of 10,000 ppm after 150 hr and at the reservoir temperature (80°C) were 36.58°, 40.76°, and 44.18° with Na2CO3, NaCl, and Na2SO4, respectively. Furthermore, the addition of NaOH improved the efficiency of the green surfactant in terms of maximizing the recovery factor by decreasing the IFT values and changing the wettability of the rock toward a more water-wet state. The final recovery factors of 88.45%, 80.87%, and 7.98% were attained using Na2CO3, NaCl, and Na2SO4, respectively, when 1 PV of NaOH was injected as the preflush, followed by 4 PVs of natural AS surfactant.

“…Among some of these methods, the adsorption method is a method that is widely used for the removal of dyes because the process is cheap, simple, e ective, and environmentally friendly (Muslim et al, 2021) . Several adsorbents have been studied and used for the removal of dyes, such as bio-adsorbents (Goyal et al, 2021;Akköz et al, 2019;Panchu et al, 2022), zeolites (Youssef et al, 2021Domenzain-Gonzalez et al, 2021;Abdelrahman, 2018), bentonite (Shirazi et al, 2020;Saja et al, 2020;Fabryanty et al, 2017), metal-organic frameworks (MOFs) (Sriram et al, 2021;Feng et al, 2022;Kiwaan et al, 2021), graphite (Yin et al, 2021;Verma et al, 2020;Tian et al, 2021), and layered double hydroxide (Rashed et al, 2022;Wijaya et al, 2021;Siregar et al, 2021).…”

Modification of Mg/Al-LDH intercalated metal oxide (Mg/Al-Ni) was successfully formed by the coprecipitation method at pH 10, which is indicated by the XRD diffraction, FTIR spectrum, and BET analysis. Mg/Al-LDH increased surface area after intercalated Ni from 8.621 m2/g to 9.821 m2/g and improved performance in process regeneration which can be used in the three cycles. Mg/Al-LDH after intercalated metal oxide (Ni) increases adsorption capacity of is 69.930 mg/g to 71.429 mg/g for methyl orange (MO) and 77.519 mg/g to 98.039 mg/g for methyl red (MR). Equilibrium time on the adsorption process occurred at 90 minutes with adsorption kinetics followed pseudo-second-order (PSO). Thermodynamic parameters indicate that the adsorption process is spontaneous and endothermic with the physical adsorption process.
