Flue Gas Purification

The research presented by the authors in this paper focused on understanding the behavior of mercury during coal combustion and flue gas purification operations. The goal was to determine the flue gas temperature on the mercury emissions limits for the combustion of lignites in the energy sector. The authors examined the process of sorption of mercury from flue gases using fine-grained organic materials. The main objectives of this study were to recommend a low-cost organic adsorbent such as coke dust (CD), corn straw char (CS-400), brominated corn straw char (CS-400-Br), rubber char (RC-600) or granulated rubber char (GRC-600) to efficiently substitute expensive dust-sized activated carbon. The study covered combustion of lignite from a Polish field. The experiment was conducted at temperatures reflecting conditions inside a flue gas purification installation. One of the tested sorbents—tire-derived rubber char that was obtained by pyrolysis—exhibited good potential for Hg0 into Hg2+ oxidation, resulting in enhanced mercury removal from the flue. The char characterization increased elevated bromine content (mercury oxidizing agent) in comparison to the other selected adsorbents. This paper presents the results of laboratory tests of mercury sorption from the flue gases at temperatures of 95, 125, 155 and 185 °C. The average mercury content in Polish lignite was 465 μg·kg−1. The concentration of mercury in flue gases emitted into the atmosphere was 17.8 µg·m−3. The study analyzed five low-cost sorbents with the average achieved efficiency of mercury removal from 18.3% to 96.1% for lignite combustion depending on the flue gas temperature.

The existing method for selecting the structure of a power plant for thermally recycling municipal solid waste (MSW) in the Russian Federation does not address the matter of selecting all components of an energy complex operating on MSW, but places focus on determining the best accessible waste thermal neutralization technology. This generates the need to search for new methods and to select criteria of choosing the structure for each particular project. A comparative analysis of various structural schemes of waste-to-energy plants widely used outside of Russia will make it possible to reveal their main advantages and drawbacks, and to determine their application fields. The article describes the statistical indicators characterizing the operation of the flue gas purification system from acid gases, which can be applied in performing a feasibility study, intellectual property assessment, and in carrying out front-end engineering. For waste-to-energy plants constructed in an urban environment and aimed to operate with keeping to a minimum the gross emissions of acid gases into the atmospheric air, the use of a wet reactor system is recommended, which will ensure low emissions of HF, HCl, and SOx. The system with a wet reactor will make it possible to reduce gross emissions of harmful substances during the operation of large capacity waste-to-energy power plants and will be a justified choice in such case. In constructing medium capacity waste-to-energy plants (with a throughput of up to 350 000 t of MSW per annum), semi-dry and dry reactors can be used; for such plants, the technology involving the use of a semi-dry reactor is the most preferred one.
