Abstract:
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.

Abstract:
This study investigated influences of the open/close states of pores and porosity distribution of activated coke on the mechanical strength of common activated coke for the purification of coal-fired flue gas by analyzing pore structure, abrasive resistance, and compression strengths of 9 types of desulfurization and denitration activated cokes. Research conclusions are conducive to disclosing the influences of porosity characteristics of activated coke for the purification of coal-fired flue gas on mechanical strength, decreasing the physical consumption of activated coke in the recycling of flue gas purification systems, and lowering the purification cost of coal-fired flue gas. According to research results, pores in the ranges of 0–2 nm and 2–500 nm of activated coke are further developed after recycling using the coal-fired flue gas purification system, and the average compression strength of activated coke is about 70% of the added fresh activated coke. However, the abrasive resistance of the recycled activated coke which has a smooth surface is higher than that of the fresh activated coke. Open pores are the main cause of reduced compression strength of activated coke. Open pores in the range of 2–500 nm can destroy the compression strength of activated coke the most. The open/close states of pores cause no significant impacts on the abrasive resistance of activated coke, but pores with diameters ranging from 0–2 nm can destroy the abrasive resistance of activated coke most significantly.

Abstract:
The optimal parameters of catalytic purification of flue gases from SO2 and CO2 in trifluoroacetic acid solutions are determined. It is shown that flue gas cleaning from carbon dioxide and sulfur dioxide using trifluoroacetic acid solutions as a catalyst is carried out at room temperature and atmospheric pressure with an efficiency of 100%. The process of gas purification from sulfur dioxide and carbon dioxide is carried out in a non-aggressive medium of trifluoroacetic acid (TFA) solutions. The possibility of increasing the absorption capacity of the reaction medium by pumping the exhaust gases through trifluoroacetic acid solutions has been established. At the same time, polluting waste gases — toxic sulfur and carbon oxides — are converted into higher oligomers (oxides), and then, as a result of their interaction with water, present directly in the reaction medium — TFA aqueous solution, into the corresponding acids. The formation of trifluoroacetic acid esters to a lesser extent leads to an increase in the absorptivity of the reaction medium, a reduction in the number of regeneration stages, a simplified separation of by-products, and, consequently, a simplification of their utilization process due to the absence of the need to purify the latter from these esters.

Abstract:
The results of laboratory studies carried out to identify the possibility and effectiveness of technologies for the complex recycling of components of flue gases and wastewater from thermal power plants and industrial boilers are presented. The following factors were investigated: the degree of saturation of water solutions with carbon dioxide, the efficiency of using these solutions for the regeneration of cation exchangers, the properties of regeneration solutions intended for the regeneration of cation exchange filters prepared using components of flue gases obtained from the combustion of organic fuel in the laboratory by saturating water of various compositions, the degree of saturation of condensate and waste water with components of flue gases, as well as the degree of regeneration of cation exchangers with such regeneration solutions. After research in the laboratory, a laboratory installation was created in an industrial environment to determine the properties of solutions obtained from wastewater and flue gases obtained after production processes at a power plant. The technologies were developed for the complex recycling of flue gases and waste water from thermal power plants with the production of carbon dioxide with a purity of 99.9%, technical nitrogen with a purity of 95%, special solutions for the regeneration of cation exchangers in water purification plants of industrial enterprises. The results obtained make it possible to minimize the volume of emissions into the atmosphere and the volume of waste water from thermal power plants

Abstract:
The problem of reducing emissions of sulfur dioxide from the flue gases of coal-fired TPPs is highly relevant for domestic energy in connection with the annual increase in coal production. This article analyzes statistical data in the field of coal mining, describes the current state in the field of gas purification and ash collection in the mining and metallurgical industry of the Russian Federation. To regulate pollutant emissions by stationary sources in Russia, a system of maximum permissible and temporarily agreed emissions (MPE and ENV) was introduced. The country takes part in international programs aimed at protecting the environment from the harmful effects of human activity. Despite the general dynamics of reducing air pollution in the Russian Federation, emissions from mining and metallurgical enterprises only increase. This is due to deficiencies in the technical condition and operation of dust and gas cleaning equipment at electric power enterprises. The main ones are the moral and physical deterioration of the equipment fleet, the need for reconstruction and modernization of devices. The average degree of flue gas cleaning from ash at Russian TPPs is 95.5 %, which is noticeably less than abroad. Efficiency of the gas treatment plants used does not meet modern environmental requirements. The flue gases at our TPPs are not cleaned from sulfur and nitrogen oxides; there are practically no devices for continuous monitoring of TPP emissions. The article provides the rationale for the transition of enterprises to the best available technologies (BAT) in the field of gas purification. The use of a gas conditioning system allows 30 – 40 % reduction in the amount of funds spent on the construction of electrostatic filters. In recent years, in connection with the advent of new technologies for burning coal, filters for the purification of hot gases made of ceramic materials have been created. We have analyzed the state of gas purification and ash collection in the mining and metallurgical industry of the Russian Federation and its impact on the atmosphere. An assessment of the current state of gas purification equipment at the enterprises was carried out.

Abstract:
Polymers rich in primary amine groups are proposed to be effective adsorbents for the reversible adsorption of CO2 from moderately dilute gas streams (10% CO2) and ultra-dilute gas streams (e.g. ambient air, 400 ppm CO2), with their performance under ultra-dilute conditions being competitive with or exceeding the state-of-the-art adsorbents based on supported poly(ethyleneimine) (PEI). The CO2 adsorption capacity (mmol CO2/g sorbent) and amine efficiency (mmol CO2/mmol amine) of linear poly(allylamine) (PAA), cross-linked poly(allylamine) prepared by post-polymerization crosslinking with epichlorohydrin (PAAEPI), and branched poly(allylamine) prepared by branching of poly(allylamine) with divinylbenzene (PAADVB) are presented here and compared with state-of-the-art adsorbents based on supported PEI, specifically branched and linear, low molecular weight PEI. Silica mesocellular foam, MCF, serves as the support material for impregnation of the amine polymers. In general, branched polymers are found to yield more effective adsorbents materials. Overall, the results of this work show that linear PAA, cross-linked PAAEPI, and branched PAADVB are promising candidates for solid adsorbents with high capacity for CO2.

Abstract:
Coal is now used mainly as fuel for the production of electricity. Worldwide about 28% of commercial energy production depends on coal. In the United States it is about 31% and in some coal rich but oil poor countries such as China, Germany, Poland and the Czech Republic the figures are 73%, 56%, 95% and 86%, respectively (1). Because of the ample supply of available coal, dependence on coal as an energy source will probably remain high for some time to come. However, coal is the most polluting of all fuels; its main pollutants are sulfur dioxide and suspended particulate matter (SPM). Depending on its origin, coal contains between 1 and 2.5% or more sulfur. This sulfur comes in three forms: pyrite (FeS2), organic bound sulfur, and a very small amount of sulfates (2). Upon combustion, about 15% of the total sulfur is retained in the ashes. The rest is emitted with flue gases, mostly as SO2 but also, to a lesser extent, as SO3. This mixture is frequently referred to as SOx (2). The three basic approaches to the control of SOx emission are prepurification of coal before combustion, removal of sulfur during combustion, and purification of flue gases. The first approach, referred to as a benefication process, is based on a difference in specific gravity between coal (sp gr = 1.2–1.5) and pyrite (sp gr = 5). Although the technical arrangements may vary, in essence the procedure involves floating the crushed coal in a liquid of specific gravity between that of pure coal and that of pyrite. Coal is removed from the surface while pyrite and other minerals settle to the bottom. Coal benefication can reduce sulfur content by about 40% (2). Although gravity separation is presently the only procedure in use, research was initiated on microbial purification of coal. A research project conducted by the Institute of Gas Technology, with funding from the U.S. Department of Energy, was aimed at the development of genetically engineered bacteria capable of removing organic sulfur from coal. Inorganic sulfur can be removed by the naturally occurring bacteria Thiobacillus ferrooxidans, Thiobacillus thiooxidans, and Sulfolobus acidocaldarius (3).

Abstract:
This paper presents experimental study of fluidized absorption process for flue gas purification of co-combustion of municipal solid waste (MSW) and coal in a circulating fluidized bed Combustor (CFBC) test rig. The test rig is composed of a CFBC, coal/MSW feeding subsystem, ash cycle subsystem and flue gas purification subsystem. In the circulating fluidized bed, section area of fluidized bed is 230mm × 230mm and the freeboard is 460mm × 395mm. The total height of the test facility is 8m; height of bed and freeboard are 1.5m and 6m respectively. The preheated air enters the bed as primary air passing through distributor and provides oxygen for combustion. Six movable tubes immerged within the bed are used in adjusting the bed temperature. The cyclone separator is fixed up at the exit of chamber. The separated ashes return to chamber through the recycling feeder for decreasing the carbon content in fly ash and promoting the combustion efficiency. The flue gas from the exit of cyclone separator enters the air preheater to preheat the cold air at first, then enters the flue gas purification facility, finally be discharged into air by induced drafted fan passing through the stack. Coal is carried to a positive pressure feeding entrance by screw feeder and enters the bed. Secondary air is injected into a sealed end feeding pipe under MSW feeder, for enhancing the mixture in furnace, providing the oxygen for combustion and preventing from MSW remaining in the feeding pipe. The material of bed is silicon sand. Fluidized absorption facility for flue gas purification in MSW incineration is mainly composed of humidification system, absorption tower, flue gas reheater, fabric filter, slurry making pool, sediment pool and measurement subsystem. The temperature of flue gas from boiler by induced draft fan reduces to 120°C when flue gas enters the humidification region, which can increase the ability of acid gas absorption and prevent the slurry evaporation. When flue gas and limestone slurry enter the absorption tower, the three-phase material of gas, liquid and solid generates intense mixing and forms bubbling layer. The acid gases in flue gas are absorbed by limestone slurry, and a large amount of dusts are collected in reaction tank. Feeding oxidation air into slurry and agitating slurry simultaneously so as to promote the inner circulation of slurry and oxygenization of calcium sulphite. Flue gas passes through undulate demister which has high efficiency and low resistance, then enters fabric filter after reheating, finally be discharged into the stack by induced draft fan. The mixture of slurry and gypsum is emitted into the sediment pool through bottom and clear liquid in sediment pool returns to slurry making pool or absorption tower. The test results are as follows: the combustion efficiency is greater than 95%, the carbon content of fly ash is lower than 8%, and the loss of slag combustion is lower than 5%. When sorbent is limestone slurry, the concentration of slurry is 1%, the circulating ratio is 3, the jet rate is 5∼15m/s. The immerged depth of bubbling pipe under the slurry is 140mm. In the fluidized absorption facility for flue gas purification of MSW incineration, the desulfurization efficiency is >90%, the de-nitrification efficiency is 20∼30%, the de-chlorination efficiency is >80%, the removal efficiency of dust, heavy metal and dioxins are >99%, >98.6% and 99.35% respectively. After passing through fluidized absorption facility for flue gas purification of MSW incineration, when the concentration of O2 is 11%, the emission concentration of every components in flue gas are: SO2 is 20∼50mg/Nm3, NOx is 130∼270 mg/Nm3, HCl is 7∼12 mg/Nm3, HF is ∼8 mg/Nm3, CO2 is7∼8%, dust is 23∼67 mg/Nm3, Cr is 0.2172 mg/Nm3, Cu is 0.0454 mg/Nm3, Pb is 0.2963 mg/Nm3, Zn is 0.2074 mg/Nm3, Fe is 2.834 mg/Nm3, As is 1.112 × 10−3 mg/Nm3, Hg is 2.38 × 10−4 mg/Nm3 and dioxins is 0.1573 ng/Nm3. These emission concentrations are all lower than the Chinese emission standards. Some of them come close to the emission standards of developed country.

Abstract:
This paper presents the process design and the energy analysis for a coal-fired power plant based on pressurised oxycoal combustion and including carbon capture technologies. A combustion technology performing a pressurised combustion of coal in an atmosphere of O2/CO2/H2O and including flue gases recycling has been selected. Combustion and steam production occur in separated equipments and the combustor’s design allows achieving high ash removal efficiency. The Rankine cycle has been chosen as the most viable thermodynamic cycle in a short-term scenario. Oxygen required by the combustion process is supplied by a cryogenic Air Separation Unit (ASU) and a double-reheat ultrasupercritical cycle is employed with main steam conditions of 250bar/605°C and reheat steam temperatures of 605°C/620°C. All choices related to thermal cycle selection and process design have been conducted upon the principle of feasibility and reliability. In order to increase net plant efficiency both sensible and latent heat is recovered from the flue gas stream before entering the purification and compression section. By operating in pressure it becomes possible to recover a larger amount of heat than in the atmospheric case. As a result, all low pressure steam bleedings and the corresponding regenerative heat exchangers can be eliminated. Process simulation is carried out in the paper and the expected efficiency is evaluated, as well as other cycle performance parameters. Since a relevant benefit may arise from the combustion of cheap coals, the impact of burning high-ash content and low ash-fusion-temperature coals is assessed. The impact of energy penalties associated to oxygen production and the benefit arising from high heat-transfer coefficients due to the increased pressure of the flue gas are deeply investigated.
