Conversion of Calcium Sulfite to Calcium Sulfate. Will Be Able to Work precipitate out so severely in your actual scrub- bing system so there is -- there are soma reasons why it worked out better, And one of the main reasons is in that they get a much more effective conversion of calcium sulfite to calcium sulfate. And there you can actually separate out the excess calcium sulfate quicker and not carry as much in excess. Is it therefore your opinion that scrubbers on low sulfur coal work better than scrubbers on high sulfur coal? It appears that the limestone-lime slurry scrubbers will be able to work better or will be able to work at a greater reliability than a -- on a low sulfur coal than a high sulfur coal. You would be getting into a more problematic operation with the higher sulfur coal. MR, FRAWXIEY: Thank you, that is all, COMMISSIONER DOWNIE: May 1 ask a question? Doctor Vickers, tell me j i I misunderstood you but I understood and I think in refere me to Item Three of your prepared testhciny and 1 may be rrong on that, in your answer you indicated to me I 1 that it w s totally jmpractical to tq to identifl the 4 percentag of pollution emitted by individual industries, paper mil s or power plants or any other.industry? rn WIrnSS: I There are emission studies that have c been done you know, there have been studies of how much, 1 how many ounds have been emitted and there are, ycu can E get pies ike they do on the tax dollars how much cf this 5 type indu try is responsible for and how much power genera- I( tion and 0: forth but these are roughly figure and for any 11 specific rea you really have to have -- the Pollution Ii Control C ,mission 3: understand has done this emission on 12 le emissi In in an article and puts out why but to say where 14 it goes a .d who is responsible for what particular damage 1s once it i done, that becomes a problem of allocating it ?E and then dentifying why your paint on the house has to be 17 redone gu cker instead of five years it has to be done every IE three yea s and who is responsible for it or why.

THE WITNESS: 1 You are -- well, when you get into 1 health a :fects and I think we should strive to do what is 1 best ava lable, best that we can do and even accept some 1 problems on trying to keep the levels low, Now whqt we 1 know abo t sulfur oxides is -- the fate of what happens to I I 1 .ot very clear and it indicates that they could do i emi is 1 ' or would do quite a bit of damage and therefore, it would 1 in my ow philosophy would be that we should take an extra 1 little m asure and try to reduce the amount and what really 2 concerns me more than anything else, is that if we continue 2 to go to tall stacks and law sulfur coal and if we continue 2 t to have great use of power we are giving our grandchildren I 2 I or our c ildren a tremendous headache in twenty yegrs, 2 e won't have a local pollution problem -- that we 2 i Because 3243 1 through the region.

  • Multiphase Oxidation of SO2 by NO2 on Caco3 Particles 2 Defeng Zhao*, Xiaojuan Song*, Tong Zhu, Zefeng Zhang, Yingjun Liu
    1 Multiphase Oxidation of SO2 by NO2 on CaCO3 Particles 2 Defeng Zhao*, Xiaojuan Song*, Tong Zhu, Zefeng Zhang, Yingjun Liu 3 BIC-ESAT and SKL-ESPC, College of Environmental Sciences and Engineering, Peking University, Beijing, 100871, China 4 *These authors contributed equally to this work. 5 Correspondence to: Tong Zhu ([email protected]) 6 Abstract. Heterogeneous/multiphase oxidation of SO2 by NO2 on solid or aqueous particles is thought to be a 7 potentially important source of sulfate in the atmosphere, for example, during heavily polluted episodes (haze), 8 but the reaction mechanism and rate are uncertain. In this study, in order to assess the importance of the direct 9 oxidation of SO2 by NO2 we investigated the heterogeneous/multiphase reaction of SO2 with NO2 on individual 10 CaCO3 particles in N2 using Micro-Raman spectroscopy. In the SO2/NO2/H2O/N2 gas mixture, the CaCO3 solid 11 particle was first converted to the Ca(NO3)2 droplet by the reaction with NO2 and the deliquescence of Ca(NO3)2, 12 and then NO2 oxidized SO2 in the Ca(NO3)2 droplet forming CaSO4, which appeared as needle-shaped crystals. 13 Sulfate was mainly formed after the complete conversion of CaCO3 to Ca(NO3)2, that is, during the multiphase 14 oxidation of SO2 by NO2. The precipitation of CaSO4 from the droplet solution promoted sulfate formation. The -8 15 reactive uptake coefficient of SO2 for sulfate formation is on the order of 10 , and RH enhanced the uptake 16 coefficient. We estimate that the direct multiphase oxidation of SO2 by NO2 is not an important source of sulfate 17 in the ambient atmosphere compared with the SO2 oxidation by OH in the gas phase and is not as important as 18 other aqueous phase pathways, such as the reactions of SO2 with H2O2, O3, and O2, with or without transition 19 metals.

  • Fgd) By-Products
    CHARACTERIZATION OF TRACE ELEMENTS IN DRY FLUE GAS DESULFURIZATION (FGD) BY-PRODUCTS DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Panuwat Taerakul, B.ENG., M.B.A., M.S. ***** The Ohio State University 2005 Dissertation Committee: Approved by Professor Harold Walker, Adviser Professor Linda Weavers Dr. Tarunjit Butalia Adviser Professor Yu-Ping Chin Civil Engineering Graduate Program ABSTRACT This study investigates the amount, distribution, variation and fate of trace elements in FGD by-product. Dry FGD by-product including lime spray dryer (LSD) ash have possible uses in agricultural and construction applications. However, the variability in the chemical properties, especially levels of trace elements, of LSD ash is a concern due to the possible release to the environment. Changes in levels of inorganic constituents in LSD ash collected from the McCracken Power Plant were measured. Variability of elemental composition in leachate and bulk chemical properties (i.e. available lime index (ALI), calcium carbonate equivalent (CCE), and total neutralization potential (TNP)) were also examined. Little variability over different time periods (e.g., daily to yearly) and little variability between samples collected from different particle collection hoppers were observed. Trace elements including As, Se, and Hg in LSD ash and in the leachate did not surpass limits for land application (EPA 503 Rule) or RCRA. Therefore, LSD ash is a consistent material which can be beneficially re-used in an environmentally sound manner. ii Further study of LSD ash samples was conducted to examine the distribution of trace elements in different fractions.

Dick1 1School of Natural Resources, The Ohio State University/The Ohio Agricultural Research and Development Center, Wooster, OH, USA. 2Ag Spectrum Company, Dewitt, IA, USA. 3School of Natural Resources, The Ohio State University, Columbus, OH, USA. KEYWORDS: FGD-sulfite, FGD-sulfate, soil quality, gypsum, coal combustion products ABSTRACT The use of high-sulfur coal for power generation in the United States requires the removal of sulfur dioxide (SO2) produced during burning in order to meet clean air regulations. If SO2 is removed from the flue gas using a wet scrubber without forced air 2- oxidation, much of the S product created will be sulfite (SO3 ). Plants only take up S in 2- 2- the form of sulfate (SO4 ), and SO3 is toxic to plants and may cause damage to plant 2- roots. For agricultural uses, SO3 in flue gas desulfurization (FGD) products must 2- oxidize to SO4 in soils before crops are planted. However, there is little information 2- 2- about the oxidation of SO3 in FGD product to SO4 under field conditions. An FGD- CaSO3 obtained from American Electric Power Company was applied at rates of 0, 1.12 and 3.36 Mg ha-1 to the surface of an agricultural soil (Wooster silt loam, Oxyaquic 2- Fragiudalf). The SO4 in the surface soil (0-10 cm) was analyzed on days 3, 7, 17, 45, 2- and 61.

  • A Great Tool for Flue Gas Desulfurization Solids Analysis
    Thermogravimetry: A Great Tool for Flue Gas Desulfurization Solids Analysis Brad Buecker Kansas City Power & Light Company, La Cygne, KS, USA and Roger Blaine*, Ph.D. TA Instruments, 109 Lukens Drive, New Castle, DE 19720, USA INTRODUCTION Over 50 percent of the electricity generated in the United States comes from coal- fired power plants. Perhaps a hundred or so utility boilers are already equipped with flue gas scrubbers. Anticipated tightening of sulfur dioxide (SO2) emissions regulations will require other existing and new plants to also install scrubbers. A popular design has been and will be the wet-limestone type, where finely ground, slurried limestone is sprayed onto the flue gas to remove SO2. Reliable monitoring of scrubber solids chemistry is critical for proper operation of scrubbing systems. Thermogravimetry is an excellent tool for these analyses. A Brief Overview of Scrubber Chemistry Flue-gas scrubbing is a step-wise chemistry process, where the overall reaction is a classic example of aqueous acid-base chemistry applied on an industrial scale. Alkaline limestone slurry (composed primarily of calcium carbonate, CaCO3) reacts with acidic sulfur dioxide, as represented in Equation 1. + -2 +2 -2 CaCO3 + 2H + SO3 → Ca + SO3 + H2O + CO2↑ (1) In the absence of any other reactants, calcium and sulfite ions will precipitate as a hemihydrate, where water is actually included in the crystal lattice of the scrubber byproduct. +2 -2 Ca + SO3 + ½H2O → CaSO3·½H2O↓ (2) Proper operation of a scrubber is dependent upon the efficiency of the above- listed reactions. Control of pH via reagent feed is very important. Many wet-limestone scrubbers operate at a solution pH of around 5.6 to 5.8.

    The Pennsylvania State University The Graduate School EVALUATING THE USE OF FLUIDIZED BED COMBUSTION FLY ASH AS CONCRETE POZZOLAN A Dissertation in Civil Engineering by Mona Zahedi © 2019 Mona Zahedi Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy December 2019 The dissertation of Mona Zahedi was reviewed and approved* by the following: Farshad Rajabipour Associate Professor of Civil and Environmental Engineering Dissertation Advisor Chair of Committee Shelley M. Stoffels Professor of Civil and Environmental Engineering Tong Qiu Associate Professor of Civil and Environmental Engineering Aly Said Associate Professor of Architectural Engineering Patrick J. Fox Head of the Department of Civil and Environmental Engineering *Signatures are on file in the Graduate School iii ABSTRACT Supplementary cementitious materials (SCM) are a key ingredient of today’s concrete and can vastly improve the durability and sustainability of concrete mixtures. While the demand for fly ash and other suitable pozzolans continues to escalate, the supply of high-quality and economically available fly ash has been shrinking. To maintain and expand the market share of concrete products, it is critical that high-quality, long-lasting and cost-competitive concrete is widely available; this requires a stable and abundant supply of cheap fly ash. Fluidized bed combustion (FBC) fly ash is an alternative source of fly ash that is widely available, but currently not used in concrete. This is due to the lack of guidelines and protocols to evaluate the quality/performance of FBC fly ash and identify necessary beneficiation procedures before it can be incorporated into concrete mixtures. The FBC process is a cheaper and more efficient way of burning waste coal compared to conventional pulverized coal combustion (PCC).
