Summary: A model for mercury transformations in a flue gas treatment process was established in this study. Concentrations, mass flow rates, and emission factors of mercury, NOX, PM, and SO2 were investigated in a coal-fired power plant. The mercury removal efficiency of different units, such as the SCR unit, ESP, and WFGD, were also analyzed. The proposed flue gas treatment process model is considered a feasible approach for quantitative evaluation of multi-pollutants emissions at plant level.

Summary: Field testing at a 300 MW coal-fired power station showed that selective catalytic reduction (SCR) can effectively reduce mercury content in flue gas. Commercial testing demonstrated that SCR catalyst breakage resulted in an increase in total mercury concentration at the electrostatic precipitator (ESP) inlet and outlet. Laboratory experiments confirmed the Hg0 oxidation capability of the commercial SCR catalyst.

Summary: India is a major emitter of mercury, primarily from coal combustion in power plants. Mercury content in coal samples from the SECL region in India was positively correlated with ash and sulfur. In a coal-fired power plant, 65% of the mercury in the feed coal was emitted through the stack, while the remaining portion was associated with fly ash, bottom ash, and mill rejects. The concentration of mercury in the stack gas varied, with Hg0 being higher than Hg2+. The estimated mercury emission factor was higher due to the use of high ash coal and the lack of flue gas desulphurisation system.

Summary: This study investigated the mercury emissions from coal-fired and lignite-fired power plants in India. The majority of mercury was found to be released to air through stack gas, with a significant portion captured in fly ash, especially in the case of circulating fluidised bed boilers burning lignite. The mercury emission factor ranged from 4.7 to 15.7 mg/GJ.

Summary: The study found that the main type of mercury emitted in coal-fired flue gas is gaseous mercury, and the mercury emissions from all units meet the standard requirements. SCR denitration facilities have a significant impact on mercury type, promoting the oxidation of elemental mercury into oxidized mercury that can be easily removed downstream. Particulate mercury and oxidized mercury are synergistically removed in dust removal and wet desulfurization facilities, respectively.

Summary: This study indicates that emissions from coal-fired power plants have a noticeable impact on ambient GEM and agricultural soil THg levels in the vicinity, with approximately 3.9% of the discharged mercury accumulating in nearby soils. The low retention rate of total emitted mercury by soils is attributed to the high proportion of Hg-0 in stack gas emissions and the potential loss of Hg through reemission from soil surfaces.

Summary: This study investigates the emissions of filterable particulate matter (FPM) and condensable particulate matter (CPM) from a coal-fired power plant. The results show that the concentration of CPM increases when coal is mixed with sludge. Most air pollutant control devices have a positive effect on the removal of FPM and CPM, except for the selective catalytic reduction (SCR) denitration device. The low-low temperature electrostatic precipitator has the highest removal efficiency for both FPM and CPM. The organic fraction in CPM is mainly composed of hydrocarbons and organosilicon.

Summary: This study systematically investigates the effects of adsorption temperature and flue gas components on the removal of As2O3 using Fe2O3, CaO, and gamma-Al2O3 as adsorbents. Fe2O3 demonstrates the highest removal capacity for As2O3 and shows potential as a strong arsenic removal adsorbent. Low concentration SO2 competes with As2O3 for adsorption, while the presence of NO inhibits the removal of As2O3.

Summary: This study characterizes and analyzes the effects of coal-fired flue gas components on the removal of Hg0 using a promising mercury removal adsorbent. The results show that mechanochemical S-modified petroleum coke with a theoretical sulfur content of 21% exhibits the best performance for mercury removal. O2, CO2, and NO promote the removal of Hg0, but also inhibit its adsorption. The presence of SO2 inhibits the oxidation and adsorption of Hg0, resulting in reduced removal performance.

Summary: In this study, the effects of carbon-based adsorbents on the removal of gaseous As2O3 emitted from the coal-fired power plant were investigated. It was found that BC showed the best removal ability, with the highest effectiveness at 150 degrees Celsius. Increasing the adsorption temperature facilitated the oxidation of As3+ and chemisorption mainly occurred through oxygen-containing functional groups and As2O3. The arsenic removal ability of the carbon-based adsorbents increased initially and then decreased with increasing adsorption temperature, and the change was mainly attributed to physical adsorption.

Summary: The elimination of hydrogen chloride (HCl) is crucial for coal-fired power plants to manage wastewater and ensure equipment safety. A novel ethanol-hydrated CaO adsorbent has been developed with superior HCl removal efficiency compared to traditional dechlorinators. However, the presence of SO2 in flue gas poses challenges to HCl adsorption due to competition on the alkaline adsorbent. Experiments and density functional theory (DFT) calculations were carried out to investigate the influence of SO2 on HCl adsorption and the underlying mechanisms. The results reveal that SO2 consumption of active Ca sites, reduced alkalinity, and surface activity hinder HCl removal. Moreover, DFT calculations indicate that the high adsorption energy of SO2 affects the active sites for HCl removal, leading to apparent activity shielding on the adsorbent surface.

Summary: The low-temperature deNOx performance of various zFe-CexMny catalysts was evaluated in this study. The 4FeMn7Ce3 catalyst with 4 wt% Fe based on Mn7Ce3 showed the best deNOx performance, achieving over 90% deNOx efficiency at temperatures of 120-220 degrees C. Fe doping resulted in uniform distribution of the oxide on the catalyst's surface, promoting the valence cycle and producing more Mn4+ and Ce3+ species for optimal low-temperature deNOx. The presence of Lewis acid sites on the catalyst's surface enhanced the formation of amide species, facilitating the deNOx reaction. Both E-R and L-H mechanisms were observed in the deNOx process of zFe-CexMny catalysts. These findings are valuable for the development of high-performance low-temperature deNOx catalysts.

The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
