Kalinina; E. N. Demina;The purification of industrial and surface wastewater from heavy metal ions (HMI) to requirements for the discharge of treated wastewater into natural waters is one of the most complicated environmental and technological problems. For the deep purification of waste water from the HMI, the use of cheap sorbents obtained from production waste is the most promising. One of the many-tonnage wastes of technology of inorganic substances is the sludge formed in the production of soda by the ammonia Solvay, s method. Currently, sludge is stored in sludge accumulators and is a long-term source of pollution of environmental objects. Scientific developments in the utilization of slimes with the production of building materials, etc., have not found wide practical use, which is due to the heterogeneity of the granulometric and chemical composition of the waste. Carried out X-ray phase analysis and studies of the physicochemical and chemical properties of waste samples showed that its main components are calcium carbonate (calcite) and calcium hydroxide (portlandite). It is known that the natural mineral limestone efficiently extracts HMI from aqueous solutions with the formation of less soluble basic salts, carbonates, and hydroxy carbonates of HM. It has been established that sludge samples have high sorption activity when copper(II) and zinc ions are extracted from low concentrated solutions (sorption capacity for copper ions is 35.0 mg/g, sorption capacity for zinc ions is 40 mg/g). To increase the operational properties, a method has been developed for the production of a modified granular sorbent based on the sludge of soda production, consisting in treating with sodium silicate. The effect of a dose of sodium silicate in the sorbent composition on the mechanical strength and sorption properties of the obtained samples was studied. It has been established that the introduction of 8,6% SiO2 into the sludge leads to an increase in the mechanical strength by 50–80%, and does not have a significant effect on the sorption activity of the material. The kinetic and sorption regularities of extraction of copper(II) ions and zinc on modified sorbents are revealed. Based on the analysis of the adsorption isotherms obtained, the adsorption equilibrium constants and maximum adsorption values (Amax (Cu2+) = 50.8 mg/g; Amax (Zn2+) = 97.1 mg/g) were determined. Obtained sorption materials can be recommended for wastewater treatment from HMI.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article , Other literature type 2019Publisher:Электрические станции The problem of improving the efficiency of thermal power plants over time, not only does not decrease, but increases. Such change caused by many factors. One of the most significant factors is the increase in a share of the capital equipment which service life is approximately equal settlement or exceeds it. Boiler installations, first of all, concern to the capital equipment. Increase of an overall performance of boiler installations now mainly carried out by realization of a reserve of thermal profitability. The design procedure of a degree of use of reserves of thermal profitability, methodical instructions on drawing up of reports of power stations about thermal profitability and a number of other documents are developed a management by calculation of normative values of technical and economic parameters. It is marked, that the reserve of thermal profitability depends on a level of operation and a technical condition of the equipment. And if to agree that the level of operation influences the sizes of a reserve of thermal profitability less, than the technical condition of the equipment, a natural question arises: why the size of deterioration refers to as a reserve. It completely contradicts used in operation to a condition of a reserve. Further, shown, that change of normalized technical and economic parameters practically does not influence change of the specific charge of conditional fuel and efficiency. Moreover, their interrelation can contradict common sense. It is marked, that increase of an overall performance of power units can be reached by transition from aspiration to master a reserve of thermal profitability to an opportunity of comparison of power units, their ranging, definition of weak parts and improvement of professional skill of the personnel. Актуальная проблема повышения эффективности работы тепловых электростанций со временем не только не снижается, она возрастает. Такое изменение обусловлено целым рядом факторов. Одним из наиболее значимых факторов является увеличение доли основного оборудования, срок службы которого примерно равен расчётному или превышает его. К основному оборудованию, прежде всего, относятся котельные установки. Повышение эффективности работы котельных установок в настоящее время преимущественно осуществляется путём реализации резерва тепловой экономичности. Разработаны руководство по расчёту нормативных значений технико-экономических показателей, методика расчёта степени использования резервов тепловой экономичности, методические указания по составлению отчётов электростанций о тепловой экономичности и ряд других документов. Отмечается, что резерв тепловой экономичности зависит от уровня эксплуатации и технического состояния оборудования. А если согласиться с тем, что уровень эксплуатации влияет на размеры резерва тепловой экономичности меньше, чем техническое состояние оборудования, возникает естественный вопрос: почему величина износа называется резервом. Оно полностью противоречит используемому в эксплуатации состоянию резерва. Показано, что изменение нормируемых технико-экономических показателей практически не влияет на изменение удельного расхода условного топлива и коэффициента полезного действия. Более того, их взаимосвязь может противоречить здравому смыслу. Отмечается, что повышение эффективности работы энергоблоков может быть достигнуто переходом от стремления освоить резерв тепловой экономичности к возможности сравнения энергоблоков, их ранжирования, определения слабых звеньев и повышения квалификации персонала. №8(1057) (2019)

Standard constructive solutions of elements now in use of the building are rather well studied and have an application vast experience in housing construction. In the Republic of Bashkortostan the greatest distribution was gained by constructive solutions of elements of the building, classical for mass housing construction, in particular, standard options of overlappings and coverings from monolithic and precast concrete concern to them. Well-known shortcomings of these versions of decisions can be compensated, realizing overlappings from assembly and monolithic the keramzitobetonnykh of blocks, to conforming all requirements for reliability and the heat-shielding allowing to receive the qualitative bearing building element with an optimum level of expenses and time in climatic conditions of the Republic of Bashkortostan. The proposed solutions will allow to reduce costs of 1 sq.m of overlapping to 1,5 2 times, to lose volume weight to 1,5-2 times of rather classical options from monolithic and precast concrete. The given results of the technical and economic analysis of the recommended options of overlappings (coverings) show their high efficiency and availability to projects of housing construction, including to the socially oriented housing financed from budgets of all levels. Современная градостроительная политика ставит перед строительной отраслью достаточно сложные задачи, связанные с одновременным снижением стоимости готовой продукции, ускорением производства работ, совершенствованием проектных решений, а также с повышением качества, надежности и доступности жилья. Используемые в настоящее время типовые конструктивные решения элементов здания достаточно хорошо изучены и имеют богатый опыт применения в жилищном строительстве. В Республике Башкортостан наибольшее распространение получили классические для массового жилищного строительства конструктивные решения элементов здания, в частности, к ним относятся типовые варианты перекрытий и покрытий из монолитного и сборного железобетона. Хорошо известные недостатки этих вариантов решений можно компенсировать, реализуя перекрытия из сборно-монолитных керамзитобетонных блоков, позволяющие получать качественный несущий элемент здания с оптимальным уровнем затрат и времени, соответствующие всем требованиям по надежности и теплозащиты в природно-климатических условиях Республики Башкортостан. Предлагаемые решения позволят сократить затраты на 1 м 2 перекрытия до 1,5 - 2 раз, снизить объемный вес до 1,5-2 раз относительно классических вариантов из монолитного и сборного железобетона. Приведенные результаты технико-экономического анализа рекомендованных вариантов перекрытий (покрытий) показывают их высокую эффективность и доступность для проектов жилищного строительства, в том числе для социально-ориентированного жилья, финансируемого из бюджетов всех уровней.

Подобные изменения, безусловно, можно расценивать как успех. Однако, одновременно с целена-правленным изменением структуры производства и потребления энергии в Германии возникли определенные социально-политические, экономические и юридические проблемы, требующие тщательного изучения. Дискус-сионным является вопрос о соответствии целей и предлагаемых мер их достижения, в частности, в отношении бесперебойности энергообеспечения, расширения электрических сетей, совершенствования подхода к ценооб-разованию, экологических последствий с учетом курса на тотальное расширение производства энергии за счет возобновляемых источников. Актуальными для Германии и затрагивающими энергетическую политику России являются вопросы ускоренного сворачивания ядерной энергетики и легитимности национального курса Герма-нии на продвижение зеленой энергетики в контексте интеграции с Европейским энергетическим рынком. В статье выполнен анализ указанного комплекса проблем и охарактеризована роль национального законода-тельства Германии в их решении. from wind, solar, water and biomass now provides the largest contribution to the total electricity consumption. In this respect, Energiewende can be regarded as an overall success. But in parallel to this scenario, a critical discourse has evolved concerning socio-political, economic and legal issues. The congruence of objectives and measures for example, in regards to ensuring security of supply, expansion of electricity networks, development of electricity price and envi-ronmental consequences in the course of expansion of electricity generation from renewable sources is the main focus of socio-political and economic discussions. Accelerated phase-out of nuclear energy and constitutional disputes regarding the legality of national orientation of the promotional scheme for green electricity in respect to the integration of German electricity sector in the European internal market for energy are in the centre of the debate and have a remarkable impact on the energy policy in Russia as well. Against this background, present article examines the con-tribution of German Energiewende to the resolution of complex challenges of the developed industrial society. №4 (226) (2017)

Рассмотрены классические режимы регулирования СТК, которые направлены на обеспечение нулевого потребления реактивной мощности из питающей сети и на поддержание неизменного уровня напряжения в точке общего подключения СТК и ДСП. Дополнительно в статье представлено описание разработанного режима регулирования СТК, который предназначен для контроля суммарной активной мощности дуг ДСП. Исследование влияния параметров питающей сети и режима регулирования СТК на электрические характеристики ДСП проведено с помощью математической модели электросталеплавильного комплекса «ДСП-120-СТК», разработанной в приложении Simulink математического пакета Matlab. По результатам эксперимента определены основные достоинства и недостатки рассмотренных режимов регулирования СТК, даны общие рекомендации по их применению. The paper deals with the main results of comparative analysis of static var compensator (SVC) control modes, which are used in electric power system of high and ultra-high power electric arc furnaces (EAF). Traditional SVC control modes designed for implementation of zero reactive power consumption of the steel-smelting complex and voltage stabilization at the common connection point of EAF and SVC are considered. In addition, this paper describes the developed mode, which maintains a constant active power of an electric arc furnace. The effects of supply main parameters and SVC control modes on the EAF electrical characteristics are investigated with a mathematical model of the EAF-120 and SVC-100 MVAr steel-smelting complex developed in the Matlab’s Simulink application. Thus, advantages and disadvantages of the discussed SVC control modes are determined and main recommendations for their application are given.

Quantitative estimates of changes in Russian-Chinese merchandise trade by commodity groups (in the HS classification) due to the revaluation of the CNY against the USD were obtained via the regression analysis. In the case of the revaluation of the Yuan to the US dollar the value of Russian exports may increase for such commodity groups as mineral products, chemical industry products, base metals, precious stones and metals, and vehicles. This article shows that the value of Chinese imports will decrease for such merchandise groups as transport vehicles, machinery and equipment, leather industry products, non-precious metals and products from them; in this case, the import of the food industry products, mineral products and optical instruments will decrease insignificantly. The author concludes that the revaluation of the Yuan, contributing to the growth of Russian exports and the reduction in Chinese imports, will not cause a radical change in structure of the Russian-Chinese trade. На основе показателей статистической базы данных CEIC проведена оценка воздействия динамики курса юаня на параметры российско-китайской торговли. С помощью регрессионного анализа получены количественные оценки реакций товарных групп (в классификации HS) российского экспорта в Китай и китайского импорта в Россию в зависимости от вариантов ревальвации юаня по отношению к доллару США. Обнаружено, что в условиях ревальвации юаня к доллару стоимостные объемы российского экспорта минеральных продуктов, продукции химической промышленности, недрагоценных металлов, драгоценных камней и металлов, а также транспортных средств могут возрасти.

Kalinina; E. N. Demina;The purification of industrial and surface wastewater from heavy metal ions (HMI) to requirements for the discharge of treated wastewater into natural waters is one of the most complicated environmental and technological problems. For the deep purification of waste water from the HMI, the use of cheap sorbents obtained from production waste is the most promising. One of the many-tonnage wastes of technology of inorganic substances is the sludge formed in the production of soda by the ammonia Solvay, s method. Currently, sludge is stored in sludge accumulators and is a long-term source of pollution of environmental objects. Scientific developments in the utilization of slimes with the production of building materials, etc., have not found wide practical use, which is due to the heterogeneity of the granulometric and chemical composition of the waste. Carried out X-ray phase analysis and studies of the physicochemical and chemical properties of waste samples showed that its main components are calcium carbonate (calcite) and calcium hydroxide (portlandite). It is known that the natural mineral limestone efficiently extracts HMI from aqueous solutions with the formation of less soluble basic salts, carbonates, and hydroxy carbonates of HM. It has been established that sludge samples have high sorption activity when copper(II) and zinc ions are extracted from low concentrated solutions (sorption capacity for copper ions is 35.0 mg/g, sorption capacity for zinc ions is 40 mg/g). To increase the operational properties, a method has been developed for the production of a modified granular sorbent based on the sludge of soda production, consisting in treating with sodium silicate. The effect of a dose of sodium silicate in the sorbent composition on the mechanical strength and sorption properties of the obtained samples was studied. It has been established that the introduction of 8,6% SiO2 into the sludge leads to an increase in the mechanical strength by 50–80%, and does not have a significant effect on the sorption activity of the material. The kinetic and sorption regularities of extraction of copper(II) ions and zinc on modified sorbents are revealed. Based on the analysis of the adsorption isotherms obtained, the adsorption equilibrium constants and maximum adsorption values (Amax (Cu2+) = 50.8 mg/g; Amax (Zn2+) = 97.1 mg/g) were determined. Obtained sorption materials can be recommended for wastewater treatment from HMI.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article , Other literature type 2019Publisher:Электрические станции The problem of improving the efficiency of thermal power plants over time, not only does not decrease, but increases. Such change caused by many factors. One of the most significant factors is the increase in a share of the capital equipment which service life is approximately equal settlement or exceeds it. Boiler installations, first of all, concern to the capital equipment. Increase of an overall performance of boiler installations now mainly carried out by realization of a reserve of thermal profitability. The design procedure of a degree of use of reserves of thermal profitability, methodical instructions on drawing up of reports of power stations about thermal profitability and a number of other documents are developed a management by calculation of normative values of technical and economic parameters. It is marked, that the reserve of thermal profitability depends on a level of operation and a technical condition of the equipment. And if to agree that the level of operation influences the sizes of a reserve of thermal profitability less, than the technical condition of the equipment, a natural question arises: why the size of deterioration refers to as a reserve. It completely contradicts used in operation to a condition of a reserve. Further, shown, that change of normalized technical and economic parameters practically does not influence change of the specific charge of conditional fuel and efficiency. Moreover, their interrelation can contradict common sense. It is marked, that increase of an overall performance of power units can be reached by transition from aspiration to master a reserve of thermal profitability to an opportunity of comparison of power units, their ranging, definition of weak parts and improvement of professional skill of the personnel. Актуальная проблема повышения эффективности работы тепловых электростанций со временем не только не снижается, она возрастает. Такое изменение обусловлено целым рядом факторов. Одним из наиболее значимых факторов является увеличение доли основного оборудования, срок службы которого примерно равен расчётному или превышает его. К основному оборудованию, прежде всего, относятся котельные установки. Повышение эффективности работы котельных установок в настоящее время преимущественно осуществляется путём реализации резерва тепловой экономичности. Разработаны руководство по расчёту нормативных значений технико-экономических показателей, методика расчёта степени использования резервов тепловой экономичности, методические указания по составлению отчётов электростанций о тепловой экономичности и ряд других документов. Отмечается, что резерв тепловой экономичности зависит от уровня эксплуатации и технического состояния оборудования. А если согласиться с тем, что уровень эксплуатации влияет на размеры резерва тепловой экономичности меньше, чем техническое состояние оборудования, возникает естественный вопрос: почему величина износа называется резервом. Оно полностью противоречит используемому в эксплуатации состоянию резерва. Показано, что изменение нормируемых технико-экономических показателей практически не влияет на изменение удельного расхода условного топлива и коэффициента полезного действия. Более того, их взаимосвязь может противоречить здравому смыслу. Отмечается, что повышение эффективности работы энергоблоков может быть достигнуто переходом от стремления освоить резерв тепловой экономичности к возможности сравнения энергоблоков, их ранжирования, определения слабых звеньев и повышения квалификации персонала. №8(1057) (2019)

Standard constructive solutions of elements now in use of the building are rather well studied and have an application vast experience in housing construction. In the Republic of Bashkortostan the greatest distribution was gained by constructive solutions of elements of the building, classical for mass housing construction, in particular, standard options of overlappings and coverings from monolithic and precast concrete concern to them. Well-known shortcomings of these versions of decisions can be compensated, realizing overlappings from assembly and monolithic the keramzitobetonnykh of blocks, to conforming all requirements for reliability and the heat-shielding allowing to receive the qualitative bearing building element with an optimum level of expenses and time in climatic conditions of the Republic of Bashkortostan. The proposed solutions will allow to reduce costs of 1 sq.m of overlapping to 1,5 2 times, to lose volume weight to 1,5-2 times of rather classical options from monolithic and precast concrete. The given results of the technical and economic analysis of the recommended options of overlappings (coverings) show their high efficiency and availability to projects of housing construction, including to the socially oriented housing financed from budgets of all levels. Современная градостроительная политика ставит перед строительной отраслью достаточно сложные задачи, связанные с одновременным снижением стоимости готовой продукции, ускорением производства работ, совершенствованием проектных решений, а также с повышением качества, надежности и доступности жилья. Используемые в настоящее время типовые конструктивные решения элементов здания достаточно хорошо изучены и имеют богатый опыт применения в жилищном строительстве. В Республике Башкортостан наибольшее распространение получили классические для массового жилищного строительства конструктивные решения элементов здания, в частности, к ним относятся типовые варианты перекрытий и покрытий из монолитного и сборного железобетона. Хорошо известные недостатки этих вариантов решений можно компенсировать, реализуя перекрытия из сборно-монолитных керамзитобетонных блоков, позволяющие получать качественный несущий элемент здания с оптимальным уровнем затрат и времени, соответствующие всем требованиям по надежности и теплозащиты в природно-климатических условиях Республики Башкортостан. Предлагаемые решения позволят сократить затраты на 1 м 2 перекрытия до 1,5 - 2 раз, снизить объемный вес до 1,5-2 раз относительно классических вариантов из монолитного и сборного железобетона. Приведенные результаты технико-экономического анализа рекомендованных вариантов перекрытий (покрытий) показывают их высокую эффективность и доступность для проектов жилищного строительства, в том числе для социально-ориентированного жилья, финансируемого из бюджетов всех уровней.

Подобные изменения, безусловно, можно расценивать как успех. Однако, одновременно с целена-правленным изменением структуры производства и потребления энергии в Германии возникли определенные социально-политические, экономические и юридические проблемы, требующие тщательного изучения. Дискус-сионным является вопрос о соответствии целей и предлагаемых мер их достижения, в частности, в отношении бесперебойности энергообеспечения, расширения электрических сетей, совершенствования подхода к ценооб-разованию, экологических последствий с учетом курса на тотальное расширение производства энергии за счет возобновляемых источников. Актуальными для Германии и затрагивающими энергетическую политику России являются вопросы ускоренного сворачивания ядерной энергетики и легитимности национального курса Герма-нии на продвижение зеленой энергетики в контексте интеграции с Европейским энергетическим рынком. В статье выполнен анализ указанного комплекса проблем и охарактеризована роль национального законода-тельства Германии в их решении. from wind, solar, water and biomass now provides the largest contribution to the total electricity consumption. In this respect, Energiewende can be regarded as an overall success. But in parallel to this scenario, a critical discourse has evolved concerning socio-political, economic and legal issues. The congruence of objectives and measures for example, in regards to ensuring security of supply, expansion of electricity networks, development of electricity price and envi-ronmental consequences in the course of expansion of electricity generation from renewable sources is the main focus of socio-political and economic discussions. Accelerated phase-out of nuclear energy and constitutional disputes regarding the legality of national orientation of the promotional scheme for green electricity in respect to the integration of German electricity sector in the European internal market for energy are in the centre of the debate and have a remarkable impact on the energy policy in Russia as well. Against this background, present article examines the con-tribution of German Energiewende to the resolution of complex challenges of the developed industrial society. №4 (226) (2017)

Рассмотрены классические режимы регулирования СТК, которые направлены на обеспечение нулевого потребления реактивной мощности из питающей сети и на поддержание неизменного уровня напряжения в точке общего подключения СТК и ДСП. Дополнительно в статье представлено описание разработанного режима регулирования СТК, который предназначен для контроля суммарной активной мощности дуг ДСП. Исследование влияния параметров питающей сети и режима регулирования СТК на электрические характеристики ДСП проведено с помощью математической модели электросталеплавильного комплекса «ДСП-120-СТК», разработанной в приложении Simulink математического пакета Matlab. По результатам эксперимента определены основные достоинства и недостатки рассмотренных режимов регулирования СТК, даны общие рекомендации по их применению. The paper deals with the main results of comparative analysis of static var compensator (SVC) control modes, which are used in electric power system of high and ultra-high power electric arc furnaces (EAF). Traditional SVC control modes designed for implementation of zero reactive power consumption of the steel-smelting complex and voltage stabilization at the common connection point of EAF and SVC are considered. In addition, this paper describes the developed mode, which maintains a constant active power of an electric arc furnace. The effects of supply main parameters and SVC control modes on the EAF electrical characteristics are investigated with a mathematical model of the EAF-120 and SVC-100 MVAr steel-smelting complex developed in the Matlab’s Simulink application. Thus, advantages and disadvantages of the discussed SVC control modes are determined and main recommendations for their application are given.

Quantitative estimates of changes in Russian-Chinese merchandise trade by commodity groups (in the HS classification) due to the revaluation of the CNY against the USD were obtained via the regression analysis. In the case of the revaluation of the Yuan to the US dollar the value of Russian exports may increase for such commodity groups as mineral products, chemical industry products, base metals, precious stones and metals, and vehicles. This article shows that the value of Chinese imports will decrease for such merchandise groups as transport vehicles, machinery and equipment, leather industry products, non-precious metals and products from them; in this case, the import of the food industry products, mineral products and optical instruments will decrease insignificantly. The author concludes that the revaluation of the Yuan, contributing to the growth of Russian exports and the reduction in Chinese imports, will not cause a radical change in structure of the Russian-Chinese trade. На основе показателей статистической базы данных CEIC проведена оценка воздействия динамики курса юаня на параметры российско-китайской торговли. С помощью регрессионного анализа получены количественные оценки реакций товарных групп (в классификации HS) российского экспорта в Китай и китайского импорта в Россию в зависимости от вариантов ревальвации юаня по отношению к доллару США. Обнаружено, что в условиях ревальвации юаня к доллару стоимостные объемы российского экспорта минеральных продуктов, продукции химической промышленности, недрагоценных металлов, драгоценных камней и металлов, а также транспортных средств могут возрасти.
