Flue gas cleaning with ammonia reduces SOP and 9?/032?4 NO, emissions Schulte, W. Proc. Amu. Irlr. Pirtsbq~h Coal Co,& 19%. 13, (I), 14741479. The SO?+NO, removal from power plant off-gases with ammonia is described. The Kruoo Koooers (ammonia absorbs sulfur oxides AMASOX) process for flue gas’desul~~rizat(on is explained in addition to the combined AMASOX and NO, removal technology. The ammonium sulfate solution yielded in the scrubbing process can be supplied to a fertilizer factory for further processing or directly used as a liquid fertilizer. It is possible to process this solution into a granulated, crystallised or compacted form. The equipment components for each option is presented and the costs of three different types of flue gas cleaning processes are compared.

Nelson, S. Jr. Proc. Anm. Inr. Pittsburgh Coal Conf., 1996, 13, (2), 14621467. The level of sulfur dioxide removal can reach 85% with a new duct-injection concept, called Fluesorbent dry scrubbing. It also leads to net particulate reductions and a valuable agricultural by-product instead of wastes. This paper describes the technology and the results from the Burger demonstration project.

Gongye Weisheng Yu Zhiyebing, 1996, 22, (5), 316-318. (In Chinese) Significant dust pollution is produced by the 43 factories that were studied for their control efficiencv. From 1980 to 1989, 68 workshops were completed the control measures, and 92.5% reached the standard.‘Annual monitoring for 3 years indicated that 91.l-95.2% reached the standard.
Hazardous waste stabilization with clean-coal 9?/032?8 technology ash residuals Neufeld, Ronald D. et al. WaterSci. Tech&., 1996, 34 (IO, Water Quality International ‘96, Part 6), 179-185. By-products of clean-coal technology, collected from commercial operations under steady state conditions, are reacted at bench-scale with metalladen hazardous wastes.The reaction conditions are outlined. Of the 15 heavy metals monitored, lead appeared to be the element of greatest concern both from a leaching and a regulatory point of view. Stabilized solid products of reactions were sampled for TCLP evaluations. For samples showing evidence of metal stabilization, further experimentation was conducted evaluating optimum moisture content and development of physical strength over time of curing. Results show that certain hazardous wastes are highly amenable to chemical stabilization, while others are not. The results indicated certain by-products provided superior stabilization, but did not allow for strength generation over timd.
9?/032?9 Heavy metal contamination from open-pit coal mining in Europe’s Black Triangle and possible remediation Tichy, R. and Mejstrik, V. Environ. Rev., 1996, 4, (4). 321-341. This article is concerned with the remediation of environmental pollution from open-pit coal mining of Europe’s Black Triangle demonstrating risks associated with the presence of toxic metals.
97103280 High reactivity sorbents for simultaneous removal of trace heavy metals and SO2 Ghosh-Dastidar, A. Proc. Annu. Int. Pittsburgh Coal Conf., 1996, 13, (2), 1424-1429. The efficient trace element capture of high reactivity calcium-based sorbents are investigated. Additionally, the influence of presence of Sq2 in gas phase on simultaneous capture of trace species and sulfur dioxide IS explored. High SOL concentration and high rate of sulfation and pore blocking/plugging have a profound influence of the heavy metal capture. The independent trace species interaction and simultaneous SO* and trace species interactions with the sorbent are explored at a medium to high temperature conditions and sorbent utilization is determined A simple model for sorbent utilization for simultaneous SO*-heavy metal interaction is also developed. 97103281 Hydrogeochemical reactions in the regions of leachate and groundwater of brown-coal open-pit mining piles Wisotzky, F. Grundwasser 1996,1, (314),129-141. (In German) The author describes changes in the chemical composition of aqueous and solid phases in pyrite oxidation zones of lignite mining dump aquifers. These changes are modelled.

Immobilization of heavy metals from MSW incin97103282 erator ash via use of sore1 cement Macakova. S. et al. Proc. Int. Conf. Solid Waste 7~eclr11ol.Mutruw.. 1905. llth, paper 5Cl 8 pp. A novel method to stabilize electrostatic precipitator fly ash was studied in Autumn 1993, by a research programme. The method is unique in its use of by-products from Mg processing plants to prepare magnesia cement, Sore1 cement, to stabilize municipal solid waste incinerator fly ash. Sore1 cement is a combination of MgO and M,,Cl>, current by-products of Mg processing. This programme treated fly ash prior to its disposal and studied the possibility of using a new ash concrete product. Results demonstrated successful solidification of fly ash treated hy the novel method. Results indicated that municipal waste incinerator fly ash can he used as an aggregate and can be mlxed with Sore1 cement and water to fabricate precast, concrete-like products using conventional concrete technique% Provided physical integrity is maintained, there is no concern of adverse environmental effects due to trace metal leaching when it comes in contact with rain water or groundwater.

BOlDS3/10), 4 Feb 1997, Appl. 951184,558, 21 Jul 1995, 4 pp. (In Japanese) The paper describes the treatment of flue gases containing dioxins from municipal incinerators or ash-melting furnaces. This involve\ passing through bag filters to remove dust, and then contacting with activated cake adsorbents to remove dioxins and other noxious pollutants at down stream. The spent coke adsorbents can be regenerated. screened and then reused. The method reduces lining cost and the consumption of activated coke adsorbent%

In a moving bed of copper oxide, up to 96% of SO? was removed from flue gases. The SO? removal capabilities of the absorbent increases as inlet SO, concentration decreases and absorbent flow rate increases. Up to 04%’ NO, was also removed.
97103286 Ion exchange properties of a western Kentucky low-rank coal Kuhr, .I. H. Enqy Fuels, 1997, l](2), 323-326. An evaluation was carried out on the ion exchange properties of a low-rank coal to explore its viability as an inexpensive material for removing radionuelides and heavy metals from a solution. Cobalt was used as a model metal to investigate the kinetics and thermodynamic of the exchange process and the effect that solution pH has on the exchange capacity. Additional studies with environmentally significant metals and radionuelides demonstrated that cations with higher charge density were preferentially adsorbed.
97103287 Leaching coal combustion byproducts with acidic, basic and neutral liquids Kazonich, G. and Kim, A. G. Proc. Annu. Int. PittSbLlrgh Coal Cotzf.. 1906, 13, (2). 1037-1042. US coal burning power plants will generate about IO0 million tons of combustion by-products in this year alone. When coal combustion hyproducts are placed in inactive surface or underground mines, they may react with naturally occurring fluids such as rain, groundwater. and acid mine drainage. The Pittsburgh Research Center of the United States Department of Energy (DOE) is investigating the reactions of power plant fly ash samples with various lixiviants in a series of column leaching tests. The leachate is analysed for pH, acidity or alkylation. iron, calcium, aluminum, manganese, magnesium and trace metals. Seventeen different fly ash samples have been tested and four samples are in the process of testing. The results of some completed column leaching tests are graphed and analysed. 97103288 Macroscopic to microscopic studies of flue gas desulfurization byproducts for acid mine drainage mitigation Robbins, E.

Flue gas desulfurization (FGD) by-product use to mitigate acid mine drainageis being studied by four US Geology Survey (USGS) projects. With the information from these examinations, the economic poteniial of FGD by-product markets on a national basis can be assessed.
