Environmental and Economic Efficiency of Comprehensive Technology of Sulfur Oxides, Nitrogen Oxides and Mercury Removal from Flue Gases

The article examines the problems associated with the environmental situation in resource-producing regions, the causes of which are associated with air pollution, soil, water bodies, etc. as a result of human activity, waste from industrial, including coal enterprises. To reduce the negative impact on these processes, as well as to control the ecological state, it is necessary to monitor, including from the chemical point of view, the dynamics of changes in the state of the environment, as well as its impact on a person, his life activity and the surrounding social infrastructure. We are talking about the degree of influence of the level of pollution on human health, on the quality of food consumed and industrial production, which ultimately has a significant impact on the quality of life and demographic processes at the regional level. The necessity of constant chemical monitoring of the composition of the atmospheric air of industrial cities, which is affected by human economic activity, is emphasized. This is especially true for the coal industry, depending on its distance from industrial centers, the state of treatment facilities and socio-economic opportunities for the use and application of "green" technologies. The use of scrubbers ("wet") ash collectors, traditional methods of water treatment, including the use of settling tanks and filter treatment facilities at coal mining enterprises, etc. contribute to the use of cleaning products for the reclamation of land disturbed by coal mines as a result of economic activities. Environmental policy should be implemented in accordance with the regional environmental standard adopted in the Kemerovo Region as part of the development strategy until 2035 and aimed at ensuring environmental-oriented and energy-efficient economic growth.

The article investigates the most effective methods of water purification necessary for its application in power generating systems. The need for this is due to the need for water purification, bringing it to a quality state that allows it to be used in industry. The most effective modern method of purification is the method of using of ion-exchange resins, since water purified from the mineral elements contained in it (desalting) is mainly used. One of the effective methods of desalting, from an ecological and economic point of view, is ion exchange, based on the removal of inorganic substances, heavy metal ions and other substances from the water. The essence of this method is the ability, with the help of ion-exchange resins, to sorb unwanted elements and their compounds from water. This technology allows to achieve water quality which corresponds to standards (technical norms) in various spheres of consumption. The authors show the influence of various parameters on the efficiency of the ion exchange process in order to improve the quality of desalination and reduction of wastewater. The stages of desalination of process water are considered in order to determine the state of wastewater at different stages. Proposed alternatives is economically and environmentally beneficial solutions to problem with wastewater and analysed ways of regeneration, as well as advantages and disadvantages of switching from once-through regeneration in countercurrent. In the presented designs, when using filters with different regeneration options, positive characteristics of monodisperse resins necessary for water purification in accordance with the requirements of environmental standards are determined.
