A mathematical model of frequency and power regulation in power systems with large wind power plants (WPPs), hydroelectric power plants (HPPs), and battery energy storage systems (BESSs) was developed. Using this model, we carried out a complex of studies over a wide range of changes in the power of HPPs, BESSs, and their proportions. Options are considered when HPP and BESS work separately. The conditions under which HPPs and BESSs provide a stable operation of the power system, working separately with satisfying the requirements to frequency deviation in the integrated power system of Ukraine and in the ENTSO-E energy system of the European Union are determined. A series of calculations for the joint use of HPPs and BESSs was carried out, and, as a result, recommendations were formulated on the conditions for joint operation of HPPs and BESSs.

To improve the technological features and efficiency of high-temperature processing of the dielectric materials, a reactor design with the electrothermal fluidized bed with a combined heating method was developed at the Institute of Gas of the National Academy of Sciences of Ukraine. The main purpose of this reactor is the process of applying a pyrocarbon coating to quartz sand. The principle-technological scheme of the process is given. Subsequently, quartz sand coated with pyrolytic carbon will be used to produce pure silicon carbide. The authors developed a methodology for calculating the heat balance, which allows estimating the efficiency of the reactor. A method for calculating similarity criteria was chosen for the possibility of comparing the efficiency of heat exchange in a developed reactor with other machines for thermochemical processes. A description of the heat exchange between the fluidized bed and the electrode is proposed. After further experiments, it willbe possible to make final conclusions regarding improving the technological features andincreasing the efficiency of the process of applying a pyrolytic coating to quartz sand, andalso to check the adequacy of the calculation methods. After further experiments, it will bepossible to make final conclusions about improving the technological features and increasing the efficiency of the process of applying a pyrolytic coating to quartz sand. Also, it will allow to check the adequacy of the calculation methods. Bibl. 17, Fig. 2.

The article analyzes modern methods of wastewater treatment from bioresistant pharmaceutical products and biogenic elements. Pharmaceuticals, such as anti-inflammatory drugs, analgesics, antibiotics, narcotic drugs, hormones, drugs that reduce cholesterol,etc., are often get into sewage in small quantities. They are hardly biodegradable and, passing through wastewater treatment plants without any changes, they often end up in water bodies. They have significant negative impact on aquatic ecosystems and human health, while being present in open waters even in small quantities. Among the nutrients that are also present in the wastewater, nitrogen and phosphorus compounds deserve the greatest attention. While getting into water bodies, they cause eutrophication, which isalso dangerous to ecosystems and human beings. It is shown that among modern variety of purification methods, the most suitable for removal of pharmaceutical products and biogenic elements are biochemical methods and photopurification technologies, as well as using membrane bioreactors. Biosorption-membrane methods open the possibility to use modern biotechnologies for efficient removal of bioresistant xenobiotics and reducing their negative impact on natural environment. Using photopurification technologies can help to reduce amount of nutrients discharged in surface water bodies, thus reducing their potential for eutrophication, as well as receiving additional renewable energy sources.

The radical increase in the density of spraying the flue gas stream in wet Venturi scrubbers allows to significantly increase the efficiency of these dust precipitators to the level of compliance with the European requirements for dust emissions. Such a shift in the operating mode significantly affects the nature of the processes of heat and mass transfer and has feature sthat are important to consider when reconstructing and designing wet gas cleaning plants. The mathematical modeling of the process of flue gas cleaning from fly ash particles in wet Venturi scrubbers in the conditions of excess spraying is performed, the dynamics of the main thermophysical parameters of the heterogeneous flow in a medium with variable moisture content and the influence of the droplet diameter on the efficiency of wet scrubbers are investigated. The problem of changing hydrodynamic resistance of a wet scrubber at different gas flow spraying densities has been studied; the effect of the input fly ash particles distribution on the result of dust cleaning is estimated.

Adsorption of synthesized nickel compounds from standardized test solutions of hydrocarbon(naphthenate and nickel acetylacetonate (II)) has been studied in hexane medium.Synthesized nickel compounds are present in heavy oils, oil products and heavy oilsludge. We have studied the possibility for using industrial wastes (iron-ore concentrateand bottom ash) for adsorption concentration of nickel compounds from standardized testsolutions of hydrocarbon. We have also analyzed adsorption isotherm of nickel from standardized hydrocarbon systems based on iron-ore concentrate and bottom ash. We have calculated the degree of nickel adsorption from standardized hydrocarbon systems for studied adsorbents. Study results can be used for development of the technology of thermal-adsorption demetallization of oil products and heavy oil sludge that would contributeto the efficiency of oil refining processes (the increase of refinery yield, reduction of equipment corrosion and reduction in deactivation of cracking catalysts) and improvement of the quality of oil products.

The wide application of gaseous fuels in technology and energy, its high cost, pose the task of improving the quality of its use. The task of automation of technological processes of thermal units heated by natural gas is to increase the safety of operation and the efficiency of their operation. This problem is especially acute in conditions of continuous operation of thermal units, when the state of the environment varies from day to day and from summer to winter. The temperature of the air for combustion, its humidity, the heat of combustion of the gas and the atmospheric pressure fluctuate particularly sharply. In these conditions, when putting into operation the heat unit, it is necessary to set such tinctures that, in the event of unfavorable external conditions, there always was enough oxygen to completelyburn the gas. This can be achieved by increasing the efficiency of the automatic control system of the ratio of the combustion components and the temperature parameters of the unit, according to the optimal regime for each particular technological process. To achieve this goal, we used the results of research into the chemical processes of interaction of combustion products using means for measuring the electrical parameters of a flame based on physical methods of ionization control of the combustion process. The established features and obtained results made it possible to develop a device for monitoring the ionization properties of the combustion process, on their basis, automatic control systems of burners for industrial heat x aggregates.

In operation of gas turbine plants pollution of aerosol deposits of internal elements of gas-air tracks occurs. This leads to a significant consumption of their power, contributes to increasing energy costs, reducing the operational reliability of installations, through the activation of corrosion and erosion processes. The main requirements for the components of the washing composition are: high washing ability and low corrosion activity. The choice of anticorrosive ingredients for technical detergents provides for the absence of an effect on the effectiveness of the washing composition. One of the important characteristics of technical detergents is its corrosive properties. Exactly this indicator is relevant to the evaluation of the service life of the equipment, so it was the interest to study the dependence of the rate of corrosion on surfactants. The modification of the existing TD and the polyfunctional action ingredients introduced into their composition, which promote the inten-sification of complexing and anticorrosion properties has studied.
