“…Numerical investigation conducted by Peraki et al (2018) reported an increase in oil recovery when electric current is combined with waterflooding. The improved recoveries observed in these studies were attributed to electrical double layer expansion of oil-brinerock interface, movement of charged ions from the anode to the cathode, drag-force transfer of water molecules associated with charged ion movement, disintegration of water molecules into constituent gaseous and ionic phases, movement of colloid particles, viscosity reduction and thermal mobility of reservoir fluid (Ghazanfari et al 2012;Haroun et al 2009;Peraki et al 2018;Wittle et al 2011). Some factors affecting the efficiency of EEOR in oil reservoirs include brine salinity, hydrocarbon composition (presence of polar components as found in asphaltenes), rock mineral composition and the amount of direct current passed through the reservoir.…”

Environmentally sustainable methods of extracting hydrocarbons from the reservoir are increasingly becoming an important area of research. Several methods are being applied to mitigate condensate banking effect which occurs in gas condensate reservoirs; some of which have significant impact on the environment (subsurface and surface). Electrokinetic enhanced oil recovery (EEOR) increases oil displacement efficiency in conventional oil reservoirs while retaining beneficial properties to the environment. To successfully apply this technology on gas condensate reservoirs, the behavior of condensate droplets immersed in brine under the influence of electric current need to be understood. A laboratory experiment was designed to capture the effect of electrical current on interfacial tension and droplet movement. Pendant drop tensiometry was used to obtain the interfacial tension, while force analysis was used to analyze the effect of the electrical current on droplet trajectory. Salinity (0–23 ppt) and electric voltage (0–46.5 V) were the main variables during the entire experiment. Results from the experiment reveal an increase in IFT as the voltage is increased, while the droplet trajectory was significantly altered with an increase in voltage. This study concludes that the interfacial tension increases progressively with an increase in DC current, until its effect counteracts the benefit obtained from the preferential movement of condensate droplet.

“…According to the patent, the device functions 'by creating a reducing environment where electrons are supplied to the food during its preparation', reducing oxidative damage on the food. Although the exact physic-chemist mechanism has yet to be discovered, in fields such as chromatography and crude oil extraction and refining, electric currents have been used to modify chemical reaction rates, break emulsions and partition polar compounds from complex matrices (Wang et al, 1998;Eow et al, 2001;Wittle et al, 2011). Infrared spectroscopy in combination with chemometrics has the ability to provide information about the different functional groups present in complex matrices (Guillen & Cabo, 1997;Bosque-Sendra et al, 2012), providing a valuable tool for evaluating the complexity of chemical reactions during the oxidation of edible oils.…”

Producing quality fried snacks involves monitoring the chemical processes that occur during frying to control oil degradation. Our objective was to evaluate the effects of a Novel Induction Food-Processing Device (NIFPD) on the quality indices of frying oil. Under standard frying conditions, vegetable oil samples (corn and canola) were collected during a standardised frying cycle to test oxidative stability. Fourier transform infrared spectroscopy was used to evaluate and classify samples during the frying time, and standard reference methods used to monitor the oil stability included p-anisidine value, free fatty acid content and CIELAB colour. The induction technology decreased the rate of free fatty acid and aldehyde formation. Tests also showed a marked effect on total colour difference between control and treatment (NIFPD), reducing colour degradation. Overall, our results showed that a patented induction device slows the rate of lipid degradation, resulting 7-20% reduction in formation rate of key quality parameters and significantly longer utilisation of frying oil.

“…This theory has been applied as a field of dewatering process in geotechnical engineering and environmental engineering. Ambah and Chilin gar performed convergence research that combined the studies of enhanced oil recovery, which was from oil development and recovery field, with the geotechnical engineering field [3,9,10,11].Especially, for the use of electrical enhanced oil recovery, various experiments were performed by constructing a low-power mechanism, and each characteristic was analyzed [9,10,11].In addition, Pamukcu suggested a restoration method for the industrial area contaminated with oil, studied the electrokinetic removal of hydrocarbons from clayey soil, and evaluated the removal efficiency of hydrocarbons [4,5].Theenhanced oil recovery method using electrokinetic remediation can recover oil at a low cost since it does not require additional subsidiary facilities, and was one of the important techniques that can remove ionic materials from a medium with low hydraulic conductivity (e.g., clay).This technique consumes less water compared to the existing oil recovery method which was used along with a steam injector, and also does not require additional water injection. The enhanced oil recovery method using electrokinetic remediation can minimize equipment on the ground surface, and does not require subsidiary facilities such as steam generator, compressor, fluid pump, and harmful material storage tank.…”

In this study, a gas reinjection type electrokinetic remediation treatment process (GREK) was proposed as the method for the restoration and stabilization of contaminated soil. The proposed electrokinetic remediation was a new technique, where treatment was performed by reinjecting the surplus gas, which was produced from an anode chamber, into soil, in order to remove the heavy metals and moisture that exist in clayey soil or clayey-sandy soil with low hydraulic conductivity. The manufactured samples were completed through the compression process, in which pressure was gradually increased to a final pressure of 2.11 kgf/cm 2 (30 psi) during a total of 7 days. Before the compression, the samples were taken, and the heavy metal concentration and water content were measured. For the gas reinjection type electrokinetic remediation treatment process (GREK) and non-injection type treatment method, continuous treatment processes were performed for 24 hours at a voltage gradient of 2 V/cm. The results of the water content indicated that the gas reinjection type electrokinetic remediation treatment process (GREK) was about 3% higher than that for non-injection type treatment method. The removal efficiency of chromium (Cr)indicated that the gas reinjection type electrokinetic remediation treatment process (GREK) was about 15% higher than that for non-injection type treatment method. The removal efficiency of cadmium (Cd) indicated that the gas reinjection type electrokinetic remediation treatment process (GREK) was about 22% higher than that for non-injection type treatment method. It is expected that the proposed gas reinjection type treatment method would contribute to convergence electrokinetic treatment processes in the future.
