Download or read book Plasma Discharges in Produced Water and Its Applications to Large Scale Flow written by HyoungSup Kim and published by . This book was released on 2016 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural gas from shale is a relatively clean energy source and is widely viewed as a key asset for economic growth in the U.S. Extraction of shale gas and oil through horizontal drilling and hydraulic fracturing is expected to continue to grow. Likewise, volumes of produced water, which is wastewater from oil and gas production, are also expected increase in the future. Currently, a number of different methods are used to treat produced water for surface discharge, reuse in the shale formation, and other beneficial use. The objective of the present study was to utilize plasma discharges to treat a large volume of produced water for the purpose of recycling it for subsequent fracking. To recycle produced water, both bacterial inactivation and water softening are required, which are the two main objectives of the present plasma water treatment study. The present study consists of two parts: (1) a bacterial inactivation study using both gliding arc discharge (GAD) and high frequency spark discharge and (2) the study of a spark-assisted self-cleaning (SASC) filtration technology in produced water. Note that the SASC filtration technology is a key component for plasma-assisted water softening. Microorganisms, particularly acid-producing bacteria (APB) and sulfate-reducing bacteria (SRB) in produced water, cause microbiologically influenced corrosion such as pipeline corrosion, reservoir souring, and biofouling, which are persistent problems in oil and gas production. E-coli contaminated water was used for the bacterial inactivation study, and the effects of H2O2 and low pH generated by GAD on the inactivation of E-coli bacteria were investigated at a range of water injection rates and air flow rates within GAD system. Furthermore, it was shown that the magnitude of bacterial inactivation and its energy efficiency in a large volume of water could be increased by the use of a microbubble generator to re-inject plasma byproducts in gas form to plasma-treated water enabling the residual effects of plasma water treatment to be captured and used. A new co-axial electrode system was developed for the generation of spark discharges in high-conductivity produced water. This new technology was used in both the biodecontamination and water softening parts of the present research. In static batch tests (no flow), 10-min treatment of semi-transparent produced water by spark plasma showed a 3-log reduction of APB and 2-log reduction of SRB based on the most probable number method in cfu/mL units. In once-through flow tests at water flow rate between 1 and 5 gpm, 2-log reduction of APB was observed in the case of semi-transparent produced water, whereas 1-log to 1.5-log reductions were observed in dark produced water. The energy efficiency (D-value) for APB inactivation in once-through flow tests of dark produced water was 1.7 kJ/L per 1-log reduction. The validation study for the SASC filtration technology was conducted using 10-in cartridge filters having 3- and 5-micron pores in synthetic (high conductivity) produced water and actual produced water. Tests of SASC filtration were performed at different levels of total dissolved solids (TDS) and total suspended solids (TSS) and at a range of flow rates. The present study demonstrated the validity of the SASC filtration concept with water samples having TDS levels 9́Þ 50,000 mg/L and TSS levels 9́Þ 2,500 mg/L. Pressure drops across the filter cartridges obtained with spark discharges were significantly less than baseline pressure drops (i.e., without spark discharges). Pressure drops increased consistently over time in baseline tests resulting in pump failure due to excessive pressure buildup. In summary, the present study demonstrated the feasibility of plasma treatment of wastewater from shale-oil and shale-gas exploration. In particular, the present study validated that the plasma water treatment could be done in an energy-efficient manner in a large enough scale that can be utilized by the wastewater treatment industry.

Download or read book Acidity of Plasma Activated Water from Non Equilibrium Plasma Discharges and Identification of Superoxide and Ozonide as the Conjugate Bases of Metastable Plasma Acid written by Ryan D. Robinson and published by . This book was released on 2018 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: When liquid water is treated with a non-thermal plasma discharge, a solution of reactive species is generated, also referred to as plasma activated water (PAW). For some time now, interest in non-thermal plasma treatment of liquids has been increasing in the biomedical, environmental, and agricultural fields as well as food processing. PAW solutions are sought after as advanced oxidative procedures for their oxidizing potential, ease of implementation, and wide range of reactive species produced (e.g., 8́9OH, 8́9O, H2O2, NO3-, ONOO-). These discharges can be applied near room temperature and atmospheric pressure with a variety of gases including atmospheric air. However, applying non-equilibrium discharges in oxygen or oxygen/noble gas mixtures has been shown to produce acidic solutions. The resulting acidic water solution, sometimes referred as "plasma acid", was shown to have strong but temporary oxidizing properties. The conjugate base of this oxygen plasma-produced acid remained unidentified, while existence of strong temporal water-based oxidizer offers a number of exciting potential applications. At the same time, the applicability of chemical processes observed in treatments with low power discharges used in laboratory setting non-equilibrium plasmas to higher powered discharges for upscaling to industrial needs is still not fully understood. The occurrence of acidic solutions produced from discharges in both air and oxygen environments as well the temperature dependence on the production of reactive nitrogen and oxygen species (RONS) in water were investigated in this study. The results obtained for the water treated with oxygen plasmas suggest that "plasma acid" contains unstable O2- and O3- as possible sources of the "plasma acid" anion which explains the nature and the temporary oxidizing properties of "plasma acid". Production of PAW from a gliding arc plasmatron (GAP) and with nanosecond-pulsed dielectric barrier discharge (DBD) batch treatments are used to investigate the viability of increasing power for the upscaling from laboratory to industrial settings. GAP was a source of "warm" plasma for continuous production useful to an industrial setting, while DBD was a source of cold plasma typically used in laboratory settings and direct biomedical applications. The GAP was shown to produce comparable PAW solution compositions to DBD (specifically HNO3, HNO2, H2O2, and pH), despite the increased power and elevated gas temperatures, largely attributed to the rapid cooling of the solution post treatment.

Download or read book A Novel Wastewater Treatment Method Using Electrical Pulsed Discharge Plasma Over a Water Surface written by Katsuyuki Takahashi and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical pulsed discharge plasma produces various powerful oxidizing agents, such as hydroxyl radicals and ozone, which have high oxidation potential. These species play an important role in the decomposition of persistent organic compounds in wastewater. Because highly concentrated oxidants are directly produced inside the plasma, plasma realizes high-speed wastewater treatment without pretreatment of samples, such as pH adjustment. The pulsed discharge plasma generated over the water surface and inside bubbles is highlighted as a highly efficient method for plasma generation and radical supply into wastewater. In this paper, the physical and chemical properties of the discharge plasma generated over a water surface are described. The decomposition of persistent organic compounds dissolved in wastewater, such as 1,4-dioxane, formic acid, and dichloromethane, by plasma discharge is demonstrated, and their mechanisms are discussed. These persistent compounds, which have strong toxicity and stability, can be efficiently decomposed and removed quickly from solutions by plasma treatment. Furthermore, the treatment of nutrient solutions used in hydroponic systems for plant cultivation is also introduced as a novel application of plasma, and the effects of bacterial inactivation, decomposition of allelochemicals, and improvement in plant growth by plasma are demonstrated.

Download or read book Plasma Catalysis written by Annemie Bogaerts and published by MDPI. This book was released on 2019-04-02 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasma catalysis is gaining increasing interest for various gas conversion applications, such as CO2 conversion into value-added chemicals and fuels, N2 fixation for the synthesis of NH3 or NOx, methane conversion into higher hydrocarbons or oxygenates. It is also widely used for air pollution control (e.g., VOC remediation). Plasma catalysis allows thermodynamically difficult reactions to proceed at ambient pressure and temperature, due to activation of the gas molecules by energetic electrons created in the plasma. However, plasma is very reactive but not selective, and thus a catalyst is needed to improve the selectivity. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood. Indeed, plasma catalysis is quite complicated, as the plasma will affect the catalyst and vice versa. Moreover, due to the reactive plasma environment, the most suitable catalysts will probably be different from thermal catalysts. More research is needed to better understand the plasma–catalyst interactions, in order to further improve the applications.
