“…The oxidation potential of O 3 is 2.07 V and has relatively higher disinfection potential than chlorine of oxidation potential 1.36 V and other oxidizing species [11,12,13]. The O 2 breaks down into two radical O then reacts with O 2 to form O 3 [14,15,16]. A remarkable progress has been made in the production and applications of atmospheric pressure cold plasma DBD for O 3 formation [17].…”

“…A remarkable progress has been made in the production and applications of atmospheric pressure cold plasma DBD for O 3 formation [17]. The main role of electrons produced in electrical discharge is to excite and dissociate O 2 molecules [7,14]. The purpose of this work is to determine the effect of the air flow rate, applied voltage, geometry of the central electrodes and discharge time on the generation of O 3 by CCDBD in cylindrical glass tube reactor which has designed according to DBD technique with air as a working gas.…”

In this research work, co-axial cylindrical dielectric barrier discharge (CCDBD) system has been used as a ozone generator for ozone production with air as a working gas. The breakdown of air was generated inside the reactor by using low line frequency of 50 Hz and high AC voltage power supply system. The variation of air flow rate (Q) was taken from 10 to 16 l/min in this experiment. The O3 concentration denoted by C(O3) decreases with increasing the rate of flow of air at fixed discharge time and applied voltage. When discharge time (t) increases, C(O3) increases at fixed applied voltage. C(O3) also increases with increasing applied voltage (V) for constant discharge time. If the gap space between the electrodes increases then C(O3) increases. We have used glass tube reactor for this work having internal diameter of 18 mm and copper, brass and iron electrodes of diameter 8 mm. It was estimated that C(O3) found higher for copper electrode than both brass and iron electrode for certain discharge time, applied voltage and reactor diameter.

“…Plasma is an ionized gas that represents the fourth state of matter after solid, liquid, and gas (Figure ). Plasma technology has been widely employed in various fields, including surface treatment, ozone production, gas cleaning, treatment of textiles, volatile organic compound (VOC) reduction, wastewater remediation, modern medicine, control of pathogenic micro-organisms, heavy oil upgrading, and so on. Plasma is classified into thermal and nonthermal.…”

To meet the requirements of sulfur standards, the desulfurization of liquid fuels is crucial. Oxidative desulfurization (ODS) has been widely employed to desulfurize liquid fuels. Various techniques can be combined with ODS to increase its efficiency. The present study surveys recent advances in the techniques of ultrasound-assisted oxidative desulfurization, plasma oxidative desulfurization, microwave-assisted oxidative desulfurization, hydrodynamic cavitation-assisted oxidative desulfurization, photocatalytic oxidative desulfurization, electrochemical oxidative desulfurization, magnetic field-assisted oxidative desulfurization, and bio-oxidative desulfurization. The advantages, drawbacks, and prospects of each method to desulfurize liquid fuels have been reviewed. All of these methods are in the research and development phases and often are at the laboratory stage. However, ultrasoundassisted ODS has been extensively investigated and its usage in industrial plants has been reported. The industrial applications of ODS and techniques assisted with ODS require more investigation.

“…It can be seen that the concentration of ozone formed becomes smaller with increasing flow rate. This is because the oxygen residence time in the reactor is getting shorter, so the amount of oxygen ionized, recombined and dissociated is smaller [28], [29], [30], [31]. Meanwhile, the ozone dose obtained increased from a flow rate of 0.1 L/minute to 0.7 L/minute.…”

Oil is one of the most popular media for the ozonation process compared to other media such as water or saline methods or direct exposure to blood. Ozonated oil has an advantage over other ozone therapy methods because ozonated oil has an antiseptic activity that is several hundred times higher than ozonated saline. Sumbawa oil is one of the local wisdom products of the Sumbawa tribal community, which is generally used as medicine or massage therapy to heal injuries such as broken bones, tendonitis, bruises, back pain and treatment of various skin wounds. An ozonation process can be carried out to increase the ability of Sumbawa oil to regenerate skin and repair tissue. Ozonation uses a Double Dielectric Barrier Discharge (DDBD) plasma reactor. The DDBD Plasma Reactor is a reactor that can produce ozone gas with very high purity. Pure ozone gas is very well applied in the medical world. This research aims to increase the peroxide levels in Sumbawa oil by ozonation using a Double Dielectric Barrier Discharge (DDBD) Plasma reactor. The flow rates used were 0.1 L/minute, 0.4 L/minute and 0.7 L/minute for 1 hour, 3 hours and 5 hours. The results showed that the peroxide value increased with increasing oxygen flow rate and ozonation time. The highest peroxide value was obtained at a flow rate of 0.7 L/minute for 5 hours, namely 332.03 mg Eq/kg Sumbawa oil. Increased by 282.71 mg Eq/kg; the peroxide figure for Sumbawa oil without ozonation was 49.32 mg Eq/kg.
