Abstract:

The essence of the research was to develop a correlation dependence between the degree of limestone grinding and the efficiency of boiler flue gas desulfurization. The design of the Installation of Flue Gas Desulfurization (FGD) in the slurry of ground limestone begins with the assumption (based on literature data or experience gained from previously completed and operated installations) of a certain pH value of this slurry in the reactor tank. The reagent is not yet indicated, its extraction location, its chemical composition, grain size and reactivity are not determined. Application practice and economics of these processes have shown that calcium reagents are the most advantageous in application because of the general availability of limestone, its large mining resources, existing infrastructure for its extraction, the network of suppliers and the purchase cost acceptable by the recipients. On a global scale, more than 90% of the flue gas desulfurization plant is treated with limestone [1]. The effectiveness of the desulfurization process is high, and some believe that the decisive influence is on the degree of limestone fragmentation dissolution rate of CaCO3 in the absorption slurry, its reactivity to absorbed SO2, the pH of the absorption slurry.

Abstract:

This paper studies the preparation of baking-free brick using the tailings of flue gas desulfurization of pyrolusite slurry, aiming to explore the optimal technological conditions. Experimental results show that the particle size of the tailings of flue gas desulfurization of pyrolusite slurry with the concentration up to 95% is below 80μm, which are the appropriate material for the preparation of baking-free bricks. "Byproduct tailings of flue gas desulfurization of pyrolusite slurry - cement cementitious materials - water" system is a relatively good ingredient program. The test results indicate that the flexural and compressive strength of the baking-free brick sample increases with the rise of forming pressure. Appropriately adding the dosage of binder could improve the flexural and compressive strength of the baking-free brick sample, but when it is added to a certain degree, the strength will decrease instead. To sum up, the optimal parameters of the baking-free brick product are shown as follows: desulfurization tailings: cementitious materials = 5:1, the forming pressure is 20 MPa, the moisture content is 10% and the natural curing time is controlled in the range of 7-28 days.

Abstract:

The wet flue gas desulfurization has been the most widely used in the coal-fired power plants because of high SO2removal efficiency, reliability and low utility consumption. A mathematical model of limestone/gypsum wet flue gas desulfurization (WFGD) system was developed based on the two-film theory of mass-transfer. In the one-dimensional two-film theory , the concentration of SO2in the bulk of the liquid(cAs) is difficult to accurately determine. The authors derive the accurate calculation of the value of cAs on the basis of the one-dimensional mass transfer model, making the model in line with the actual process. The model predictions were verified by experimental data. Experimental investigations of the effects of different operating variables on the SO2removal showed the reasonable process parameters such as the pH value of the liquid phase, droplet size of the spray and the flow rates of liquid and gas. Keep the slurry flow in a 50 ml/min, adjust the flue gas flow changes. Keep the flue gas flow in 5 l/min, adjust the flow slurry changes. The experimental results reveal that the model can describe the processes in this absorber well. Some experimental parameters (temperature, flue gas velocity) are difficult to accurately control, the model can give them fluence on the desulfurization efficiency.

Abstract:

Background & Objective: The Manganous Dithionate (MnS2O6, MD) was formed during the flue gas desulfurization process over manganese ore slurry, which impeded the following valuable using of the desulfurized lixivium. In this study, the MD formation and restraint in the desulfurization process using manganese was carefully investigated. Methods & Results: Different type of manganese oxides/carbonate was used for the flue gas desulfurization, and the MD formation with the process was detected to obtain the basic information of the MD formation and restraint. The MD was directly formed by the uncompleted oxidation of SO2 with MnO2. The increased MD formation by Mn2O3, Mn3O4 and MnCO3 was due to their influence on the pH of slurry. Processability study showed that an increase in the acidity of slurry, the gaseous oxygen content and reaction temperature could inhibit the MD formation effectively. The optimum operating conditions to restrain the MD formation were temperature higher than 60°C, 10% or more oxygen and slurry pH lower than 3. The formed MD content was different with the different manganese compounds, which cloud be controlled by the ore-proportioning in industrial application. Conclusion: Using anolyte to prepare the manganese slurry for desulfurization could perform a good MD formation restraint, which provided valuable technical support for the cleaner production of electrolytic manganese industry.

Abstract:

Secondary atmospheric pollutions may result from wet flue gas desulfurization (WFGD) systems caused by the reduction of Hg2+to Hg0and lead to a damping of the cobenefit mercury removal efficiency by WFGD systems. The experiment on Hg0reemission from limestone-gypsum WFGD slurry was carried out by changing the operating conditions such as the pH, temperature, Cl−concentrations, and oxygen concentrations. The partitioning behavior of mercury in the solid and liquid byproducts was also discussed. The experimental results indicated that the Hg0reemission rate from WFGD slurry increased as the operational temperatures and pH values increased. The Hg0reemission rates decreased as the O2concentration of flue gas and Cl−concentration of WFGD slurry increased. The concentrations of O2in flue gas have an evident effect on the mercury retention in the solid byproducts. The temperature and Cl−concentration have a slight effect on the mercury partitioning in the byproducts. No evident relation was found between mercury retention in the solid byproducts and the pH. The present findings could be valuable for industrial application of characterizing and optimizing mercury control in wet FGD systems.

Abstract:

The removal of SO2 from flue gases is necessary for eliminating haze and controlling acid rain. However, developing the traditional wet and dry flue-gas desulfurization (FGD) is challenging due to the disposal issue of several byproducts. Manganese (Mn) orebased wet FGD possesses many advantages, including good desulfurization property, low cost, and high economic benefit. The environment friendliness and reusability of MnSO4 provide new ideas and methods in the future research direction of FGD. This review summarizes the background information of Mn ore slurry desulfurization, the desulfurization mechanism, the technological process, and the desulfurization devices. The role of operating parameters, such as temperature, liquid/solid ratio, pH, SO2 concentration, and particle size, in the desulfurization efficiency and manganese leaching rate are also discussed. The temperature (20°C-80°C) has exerted little effect on the desulfurization efficiency, whereas a low pH value is beneficial for SO2 removal. Moreover, a low inlet SO2 concentration and small particle size are beneficial for SO2 removal. The control and digestion techniques related to the byproduct (manganese dithionate) are also presented, along with the future development direction of Mn ore-based wet FGD in different industries.

Abstract:

The paper presents data concerning the influence of ammonia on wet flue gas desulfurization (WFGD) absorber. Paper presents preliminary results of an industrial scale study on WFGD absorber, that collects flue gases from four boilers with total flue gas flow capacity of the WFGD equal to 1 500 000 Nm3/h. Each boiler is equipped with selective non-catalytic reduction (SNCR) with urea injection. It was shown, that ammonia present in the flue gas upstream the WFGD increases the pH of absorption slurry, impacting the desulphurization process. In addition, analysis of particulate matter upstream and downstream the absorber shows an increase of the concentration of ammonium species in the particulate matter about 14 times, as average. Moreover, a non-optimized denitrification process can cause a high NH4+ concentration in the absorption slurry (up to 768 mg/L) and raw wastewater (up to 891 mg/L).

Abstract:

Aimed at cost saving and pollution reduction, a novel desulfurization wastewater evaporation treatment system (DWETS) for handling wet flue gas desulfurization (WFGD) wastewater of a coal-fired power plant was studied. The system's advantages include simple process, and less investment and space. The feasibility of this system has been proven and the appropriate position and number of nozzles, the spray droplet size and flue gas temperature limitation have been obtained by computational fluid dynamics (CFD) simulation. The simulation results show that a longer duct, smaller diameter and higher flue gas temperature could help to increase the evaporation rate. The optimal DWETS design of Shangdu plant is 100 μm droplet sprayed by two nozzles located at the long duct when the flue gas temperature is 130 °C. Field tests were carried out based on the simulation results. The effects of running DWETS on the downstream devices have been studied. The results show that DWETS has a positive impact on ash removal efficiency and does not have any negative impact on the electrostatic precipitator (ESP), flue gas heat exchanger and WFGD. The pH values of the slurry of WFGD slightly increase when the DWETS is running. The simulation and field test of the DWETS show that it is a feasible future technology for desulfurization wastewater treatment.

Abstract:

The study regards the issues of increasing the thermodynamic efficiency of a typical condensing thermal power plant using coal-water and organic coal-water fuels as the main source. The attention is paid to the use of the phase transition heat of the water vapor of the flue gas. We have shown that it is possible to increase the power plant efficiency by about 3.7% (gross) relative to the base value (in the case of using pulverized coal). We propose to use the flue-gas desulfurization technology for creating fuel slurries in which a liquid incombustible base will be replaced, for example, with aqueous solutions of Ca(OH)2. This will create a closed water cycle, improve the efficiency of Sox flue gas purification and improve the performance of scrubbers.

Abstract:

In limestone-gypsum wet flue gas desulfurization process, the change process of pH value of slurry in absorption tower is a typical nonlinear system with time delay and various uncertainties, so it is difficult to establish an accurate mathematical model of slurry pH control process. According to the pH control process of the slurry of wet flue gas desulfurization process, a model-free adaptive control algorithm based on compact form dynamic linearization (CFDL-MFAC) is designed to realize the tracking control of the pH value of the slurry. Due to various interference factors in the pH control process of slurry in absorption tower, it is easy to cause jump change of control system parameters and even structure. Therefore, a model-free adaptive control algorithm based on switching strategy is proposed in this paper. According to different working conditions, several model-free adaptive controllers are established. The stability of the algorithm is analyzed for the two cases of fixed system parameters and jumping system parameters. It was found that the model-free adaptive controller based on the switching strategy can switch multiple controllers under the condition of system parameter jump, so as to realize the fast tracking control of the slurry pH value of the system absorption tower under different working conditions. Through this method, the overshoot can be reduced and the control quality can be improved.

Abstract:

This paper focus on the analysis of the slurry foam of the sinter band plant Wet Flue Gas Desulfurization (WFGD) process, and put forward suggestions according to the actual conditions of the Steel Works. The experimenter compared the actual operating parameters of slurry and system design parameter. Then found out the main incentive to form foam on top of the absorber’s slurry tank. This paper analyzed the major constituents of overflow foaming of WFGD system. Analysis results indicated that it is the same composition of byproducts gypsum of WFGD. So the experiment focus on the research of slurry constituents of the absorber. The result of basic data analysis shows that the slurry density of absorber is 1.25Kg/L which exceeds the maximum design value i.e.1.15Kg/L, and the Chloride concentration is 80000mg/L which exceeds the maximum design value i.e. 15000mg/L. The supernatant of slurry is formed of colloidal solution and the solid percentage of supernatant slurry is 10.64% (Weight percentage). Meanwhile the supernatant slurry shows Tyndall phenomenon significantly, and the remaining solution indicators are much higher than the design value. For identification purpose, the experimenter had an experiment about desulfurization slurry and found the relationship among solid content, supernatant concentration, foaming ability and foaming stability. Experimental results show that the foaming ability get strong first and then get weak with the increase of the solid content and the foaming ability get weak gradually with the decrease of the concentration of Mg2+and Cl-. The slurry almost has no foaming when the solid content is less than 10% and the concentration of Mg2+ less than 1000mg/L and the concentration of Cl- less than 20000mg/L.

Abstract:

Abstract The wet-flue-gas desulfurization (FGD) process plays an important role in removing water-soluble flue-gas components such as sulphur dioxide (SO2) and oxidized mercury compounds. Under the reducing environment of the FGD, there is the possibility of re-emission of the already absorbed mercury (Hg) to the gas phase, which may be diminished by the utilization of specific additives. In this study, the effect of two different additives on Hg re-emission from the aqueous phase and Hg partitioning in gypsum and filtrate of a lab-scale wet-limestone FGD is investigated. Furthermore, the behaviour of additives in the presence of different halides is studied. The studied additives are TMT 15® as a sulphidic precipitating agent, which forms non-soluble mercury compounds, and activated lignite (AL) as a carbon-based sorbent, which adsorbs Hg compounds from the aqueous phase. TMT 15® has no significant effect on SO2 absorption; on the other hand, addition of AL improves the SO2-removal efficiency by up to 30%. Using both additives, Hg re-emission is suppressed in all the experimented cases except for AL in the absence of halides, in which Hg re-emission shows no change. Thus, the need to form nucleophilic oxidized mercury compounds in the slurry for the adsorption of oxidized mercury on AL can be concluded. Usage of both additives improves Hg retention in the slurry to different extents. It is shown that, for the additive-free slurries, the Hg-adsorption capacity of the solid fraction of the slurry is the limiting parameter. Moreover, the utilization of both additives results in a significant increase in the Hg concentration of solid fraction. The correlation between redox potential and partitioning of Hg in the slurry is presented by comparing the change in the redox potential of slurries when additives are used.

Abstract:

The paper studies on wet flue gas desulfurization process and the factors of affecting the desulfurization efficiency, and analyses the control system of the absorber slurry pH value. The conventional PID control is difficult to achieve satisfactory control effect, so it puts forward the predictive control scheme based on Dynamic Matrix Control (DMC) algorithm to identify and control the change of pH value. Simulation results show that under the control of DMC algorithm, the slurry pH value has a good tracking for setting input and its changes , reflecting a high degree of adaptability. The control with low overshoot and good accuracy is better than conventional PID control and meets the requirements of real-time control.

Abstract:

In the limestone/gypsum wet flue gas desulfurization pilot-scale test rig, key parameters such as SO2 absorption rate, mass transfer were experimentally determined．The results show that desulphurizing capacity of gypsum and fly ash is relatively weaker, which is only equivalent to fresh limestone with a content of 0.27% and 1.5% respectively. pH-t curve of slurry with different levels of fly ash could be divided into a sharply increasing stage and a steadily increasing stage. The leaching content of Mn2+ is about 9 times of Fe3+ , Mn2+ can form intermediate complex with HSO3- in the solution, which can induce catalytic reaction and accelerate SO2 absorption. Fly ash in gypsum slurry can obviously promote desulfurization. The pH value of slurry is high at the initial reaction stage, and effect of fly ash on SO2 absorption rate is less than 1.5%. when the pH value is decreased to 5.0, The leaching content of Mn2+ will grow with the decrease of pH value, better catalytic efficiency can be gained, effect of fly ash on SO2 absorption rate can increase 6.0% at most. The reaction is controlled by liquid phase resistance; the ratio of gas phase resistance to overall resistance is less than 38%. Mn2+ concentration of slurry increases with pH value decreasing and fly ash concentration increasing, which has significant effect on catalyzed oxidation of SO32-.

Abstract:

Gaseous oxidized mercury (Hg2+) in the flue gas is soluble in water and can be captured effectively by Wet flue gas desulfurization (WFGD) system. But in some extent Hg0re-emission happens due to the reduction of absorbed Hg2+, and the pH of slurry is an important factor affecting Hg0re-emission. In this study, the theoretical formulas of slurry pH were derived through the conventional solution theory and then were used to evaluate the factors determining the pH of slurry. A series of laboratory experiments were carried out under N2,CO2and O2/N2atmosphere to measure the Hg0re-emission tendency at different pH values. The results show that the higher the pH, the less Hg2+reduced by S(IV), resulting in the decrease of Hg0re-emission. Under N2atmosphere, the Hg0re-emission was mild at pH>4 while it was dramatic at pH<4. Under O2/N2atmosphere, the addition of O2extended the time span of Hg0re-emission at low pH and increased Hg0re-emission unexpectedly in the latter part of the experiments at high pH. CO2atmosphere almost did not affect Hg0re-emission because of its little effect on the slurry pH.

Abstract:

The effects of limestone, Cl-, Fe3+ and Mn2+ in slurry on the characteristics of calcium sulfate dehydrate (DH) in flue gas desulfurization (FGD) process were investigated. The moisture content, particle size distribution, and crystal morphology were considered as end use characteristics of DH. As a result, the number of needle-like DH crystals was increased with increasing total contents of MgCO3, Al2O3 and Fe2O3 in limestone. Cl ions were reported to distort the crystal structure and change the crystals from orthorhombic to irregular. Mn2+ can increase the desulfurization efficiency by catalyzing the oxidation of SO2. Finally, Fe3+ will inhibit crystal growth of all faces, except {011} and {111}.

Abstract:

The flue-gas desulfurization model was studied through computational fluid dynamics software. The oxidation air was asymmetrically pumped into the slurry pond. A rotary jet mixing system was established at the bottom center of the pond to agitate the lime slurry. The Navier–Stokes equation as the control equation, the standard k–ε turbulence model, sliding grids structure, and three-dimensional Eulerian multiphase flow of lime slurry were used for the numerical simulation. The independence of the meshes and the time step was verified. The distribution of the concentration of oxidation air and influents on the velocity of flow was analyzed with five angular velocities (0.01, 0.10, 0.20, 0.50, and 1 rad/s) for the rotary jet mixing. The simulation results showed that the angular velocity has a great influence on the velocity of the slurry and the distribution of the oxidation air.

Abstract:

This paper presents development of a cleaning robot for the sludge in sulfuric acid tank. The sulfuric acid is made during SOx capturing process, well known as flue gas desulfurization, and it has very strong corrosion characteristics. The cloud of micro dust in the flue gas settles as sediment in the acid tank. Because the fume produced by the sulfuric acid is very toxic, the sulfate sludge must be removed not by a worker but by an underwater robot having anti-corrosion capability. For this purpose, an underwater robot is developed with anti corrosion materials for its elements such as robot body, drive shaft, wheel, waterproofing seal, power cable, slurry pumping tube, etc. A series of experiments of sludge cleaning shows that the developed robot works well in the real sulfuric acid tank.

Abstract:

The flue gas desulfurization process in coal-fired power plants is energy and resource-intensive but the eco-efficiency of this process has scarcely been considered. Given the fluctuating unit load and complex desulfurization mechanism, optimizing the desulfurization system based on the traditional mechanistic model poses a great challenge. In this regard, the present study optimized the eco-efficiency from the perspective of operating data analysis. We formulated the issue of eco-efficiency improvement into a many-objective optimization problem. Considering the complexity between the system inputs and outputs and to further reduce the computational cost, we constructed a Kriging model and made a comparison between this model and the response surface methodology based on two accuracy metrics. This surrogate model was then incorporated into the NSGA-III algorithm to obtain the Pareto-optimal front. As this Pareto-optimal front provides multiple alternative operating options, we applied the TOPSIS to select the most appropriate alternative set of operating parameters. This approach was validated using the historical operation data from the desulfurization system at a coal-fired power plant in China with a 600 MW unit. The results indicated that the optimization would cause an improvement in the efficiency of desulfurization and energy efficiency but a slight increase in the consumption of limestone slurry. This study attempted to provide an effective operating strategy to enhance the eco-efficiency performance of desulfurization systems.

Abstract:

Coal is still a major energy source, mostly used in power plants. However, the coal combustion emits harmful SO 2 and fly ash. Wet flue gas desulfurization (WFGD) technology is extensively used to control SO 2 emissions in power plants. However, only limited studies have investigated the synergistic dust removal by the WFGD system. Spray scrubbers and sieve-tray spray scrubbers are often used in WFGD systems to improve the SO 2 removal efficiency. In this study, the synergistic dust removal of WFGD systems for a spray scrubber and a sieve-tray spray scrubber was investigated using the experimental and modelling approaches, respectively. For the spray scrubber, the influence of parameters, including dust particle diameters and inlet concentrations of dust particles, and the flow rates of flue gas and slurry of limestone/gypsum on the dust removal efficiency, was investigated. For the sieve-tray spray scrubber, the influence of parameters such as the pore diameter and porosity of sieve trays on the dust removal efficiency was examined. The study found that the dust removal efficiency in the sieve-tray spray scrubber was approximately 1.1–10.6% higher than that of the spray scrubber for the same experimental conditions. Based on the parameters investigated and geometric parameters of a scrubber, a novel droplets swarm model for dust removal efficiency was developed from the single droplet model. The enhanced dust removal efficiency of sieve tray was expressed by introducing a strength coefficient to an inertial collision model. The dust removal efficiency model for the sieve-tray spray scrubber was developed by combining the droplets swarm model for the spray scrubber with the modified inertial collision model for the sieve tray. The results simulated using both models are consistent with the experimental data obtained.

Abstract:

Circular economy promotes the establishment of recycling-oriented society and recycling-based businesses. Circular economy is characterized by eco-efficiency improvement and materials recycle, furthermore, it also has provided a practical and feasible way for the sustainable development of human society. Materials flow analysis (MFA) has provided a new and simple way to study the development of circular economy. MFA is based on materials inputs and outputs, and then creates materials inputs and outputs account to manage materials flow. The process using pyrolusite for FGD produces manganese, high-purified manganese carbonates and slag used for cement production as byproducts. Electrolytic manganese production process, high-sulfur coal combustion process and cement production process are studied in the research. Materials flows of these processes are studied. The new production patterns are compared with the traditional ones basing on MFA. The results show that these processes are more environment-friendly and resource-saving in the comparison. To evaluate the circular economy efficiency of the complementary system, the evaluation index system of the circular economy construction is created.

Purpose This paper aims to evaluate diethylenetriamine (DETA) as an inhibitor on Q235 (Gr. D) steel in ammonia flue gas desulfurization (AFGD) system. Design/methodology/approach This research was carried out by weight loss, electrochemical measurements, scanning electron microscopy and X-ray photoelectron spectrometry. The effects of DETA on crystallization of ammonium sulfate and its co-crystallization were also investigated by X-ray diffraction and infrared spectroscopy. Findings The inhibition efficiency of DETA reached a maximum value of 98.96 per cent. DETA is postulated to adsorb on Q235 steel surface, resulting in the formation of a protective film by the accumulation of many flat particles, and the thickness of protective film is 8 μm. DETA had no effect on the crystallization of ammonium sulfate product. Originality/value DETA can be used in AFGD system as an inhibitor to protect the equipment well.

Abstract:

Reducing the adverse impacts to environment is a more and more important subject in electrolytic manganese industry. Life cycle assessment (LCA) has been a hot tool to measure the type and size of environmental impact. This paper firstly applied LCA on two different processes of producing electrolytic manganese. One process is the resourceful utilization system of high sulfur coal and low grade pyrolusite (the novel process for short)in which high sulfur coal is burned to generate power and emission SO2, then the SO2 is absorbed as reducing agent to leach the pyrolusite with 30% MnO2 grade. The other process is prevalent interiorly, called traditional process where the power is supplied by standard coal combustion, and sulfur acid leaches the manganese ore with 18% Mn grade. Life cycle software converts the original data to nine different kinds of indexes that are able to indicate types and sizes of environmental impacts. Results show that: among nine environmental impacts, the proportion of abiotic depletion potential (ADP) is biggest in both processes, but the value of the novel process is 23.25% smaller pointing the process saves more resource. All the values of other important impacts including GWP, Waste Solids, AP and RI of the novel process are less than those in traditional process. Especially, the value of acidification (AP) in novel process was -2.10×10-8 < 0, which means the novel process could control the acidification. In addition, through the composite index, using high sulfur coal in the novel process hasn’t bring any more serious impact than using standard coal. Therefore, LCA has provided rational evidence to prove that resourceful utilization system of high sulfur coal and low grade pyrolusite is more efficient and environmentally friendly and pointed which environmental impacts and life cycle links need improving . This paper could provide a reference for further environmental impact assessment of electrolytic manganese industry and an objective basis for decision-making.

Abstract:

White mud is generally known as the residue of soda ash production by ammonia-soda process. The treatment of it has been one problem in soda ash industry due to the large amount of production, strong alkalinity and corrosiveness. In China, the treatment of white mud is stacking currently, which not only occupying land but also causing environment pollution. The main composition of it is the calcium carbonate. If white mud replaces the limestone as the desulfurization agent in wet Flue Gas Desulfurization (W-FGD) system, it can attain the goal of treating the waste with another, achieve the circular economy between enterprises, and reduce the desulfurization cost significantly. In this paper, the research of white mud in 660 MW Unit W-FGD systems was investigated. Study shows that the properties of white mud and limestone are significantly different. Because of smaller particle size and active MgO, the alkaline and reaction activity of white mud are better than that of limestone, results to higher desulfurization rate and lower running cost. However, the purity of white mud is lower because of CaSO4, Cl-, and other impurities, so the dewatering system of gypsum needs to increase output by about 17%; the output of the slurry feed system needs to be increased by about 30%; the discharge capacity of wastewater needs to be increased by about 23 t/h.

The CSAB cement was synthesized by using several types of industrial waste materials such as marble dust waste and flue gas desulfurization gypsum. The raw materials were mixed in designed proportion and calcined at 1,250 °C for 2 hours. The X-ray diffraction patterns suggested the clinker consists of ~58% of ye'elimite and ~35% of belite. The slurry soft Bangkok clay with liquidity index of 1.0, 1.3 and 1.5 was stabilized with ordinary Portland cement and CSAB cement in the range of 5 - 20%.

Abstract:

Fly ash (FA) and flue gas desulphurization gypsum (FGD) were blended in proportion into a new composite binder added with cement, lime and some modifiers. In the paper, the mix proportions of composite binder with low-quality FA and FGD were studied. FA-FGD more than 80% with FA:FGD 3:2 was suggested for mortar, plastering and slurry while FA:FGD 2:1 and FA-FGD 30~40% was recommended for middle-strength concrete. Hydration process of typical mixtures of FA-FGD paste was investigated through SEM and XRD tests. The conclusion could be made that FA showed much improved pozzolana activity especially at early ages due to the existence of FGD as an ideal sulfate activator, which also crystallized later to strengthen the hardened paste. The microstructure of hydrated FA-FGD paste was more excellent than that of neat cement stone or one blended with the same percentage of pure FA.

Abstract:

Sulfite and heavy metals are crucial pollutants in the slurry produced by flue gas desulfurization. In this study, a novel cobalt-based activated carbon fiber (Co-ACFs) catalyst-adsorbent was synthesized using an impregnation method; this bifunctional catalyst-adsorbent was used in wet magnesia desulfurization for the simultaneous catalytic oxidation of magnesium sulfite and uptake of heavy metal (Hg2+, Cd2+, and Ni2+) ions. The morphology and surface chemistry of ACFs before and after cobalt loading were investigated using various characterization methods. The kinetics on catalytic oxidation of magnesium sulfite was investigated, and the effects of operation conditions on the simultaneous adsorption capacity of heavy metals were examined. Relative to a non-catalysis material, the 40% Co-ACFs material increased the oxidation rate of magnesium sulfite by more than five times. The Langmuir model can describe the adsorption behavior of Co-ACFs on Hg2+, Cd2+, and Ni2+, indicating that the simultaneous uptake of heavy metals is a single-layer adsorption process. The maximum adsorption capacities for Hg2+, Cd2+, and Ni2+ are 333.3, 500, and 52.6 mg/g, respectively. A pseudo-second-order model confirmed that the removal of heavy metals is controlled by the chemisorption process.

Abstract:

Chemical agglomeration can reduce the particulates (including PM2.5) concentration emitted from fly ash particulates and the wet flue gas desulfurization (WFGD) system. However, the calcium-based slurries affect the regulation of agglomeration compared to water, in particular, the wettability of the particulates and the viscosity of the calciumbased slurry. The wettability and the viscosity are the important factors affecting agglomeration, conversely. This manuscript studied the two factors affecting the calcium-based slurries. The sessile drop method was used to measure the contact angle. Four kinds of calcium-based slurries (CaCO3, CaSO3, CaSO4, Ca(OH)2) respectively were mixed with five kinds of wetting agents’ wet particles, and the wetting regulation was studied. The viscometer was used to measure the viscosity of the calcium-based slurry with the wetting agents, and the variation of the viscosity was analyzed as well. The results showed that the smaller the particle size was, the more it is difficult to be wet, and the wetting agents could enhance the wettability greatly, but the effect was related to the properties of the calcium-based material and the wetting agents. There were variable viscosities of different calcium-based slurries after adding the wetting agents. Overall, the Compound No. 3 had the optimal qualities in improving particle wettability and maintaining the calcium-based slurry with a high viscosity. Therefore, the Compound No. 3 is considered the optimal in facilitating chemical agglomeration.

Abstract:

Rigorous new regulations in coal-fired pollutants emissions from power plant strengthen the requirements for electrostatic precipitator (ESP) technology. The study was inspired by the requirement to use the new composite collectors as substitutes for typical steel collector to save energy and structural materials. A bench scale and a pilot scale experimental system have been set up to investigate the performance of the novel wet composite collector. Contrastive collection efficiencies of different assembled modes were investigated. The removals of coal-fired pollutants including acid aerosol, ammonia aerosol, slurry droplets and fine particles were performed in new wet ESP, as well as to quantify the key properties of the new wet ESP. The results show that the collection efficiency of the new composite collector was higher than that by typical collectors using a thimbleful of water penetrating the surface via capillary flow. The new wet ESP device acts in synergy with WFGD and SCR systems for controlling coal-fired pollutants emissions and solves the adverse impacts caused by wet flue gas desulfurization (WFGD) and selective catalytic reduction (SCR) systems at the same time.
