description Publicationkeyboard_double_arrow_right Article , Dataset 2018Publisher:O-Kratkoe Ltd Authors: I. S. Glushankova; E. V. 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.

Актуальность выбранной темы обусловлена тем, что стабильная и безопасная работа энергетического хозяйства является основой для устойчивого функционирования всех отраслей народного хозяйства. Констатируется, что энергетика играет ключевую роль во всех секторах экономики регионов и государства в целом. Утверждается, что поддержание стабильного уровня энергетической безопасности является важным условием обеспечения устойчивости комплексной системы, которая включает в себя социальные, экономические и экологические аспекты. Устойчивость данной системы во многом определяет качество жизни населения регионов и муниципальных образований и одновременно является итоговым показателем эффективности государственного управления, а также успешного экономического развития территорий. Упоминается неблагоприятное воздействие на экологическую среду и человека со стороны энергетического сектора как одной из угроз энергетической безопасности регионов и государства в целом. Подчеркивается, что государство не в силах развивать всю энергетическую сферу только за счет бюджетных средств, а поэтому абсолютно необходимо участие бизнеса в инвестициях, направленных на поддержание и реконструкцию электросетевой отрасли. Отмечается, что органы власти направляют определенные усилия на систематизацию нормативно-правовой базы в области государственно-частного партнерства (ГЧП). Реализация механизмов ГЧП должна обеспечить положительную динамику на стабилизацию энергетической безопасности в регионах. Отмечается, что данные факты свидетельствуют о заинтересованности органов власти в развитии данного механизма как эффективного инструмента реализации государственной энергетической политики для обеспечения долгосрочного развития регионов РФ. Предлагаются конкретные мероприятия, реализация которых будет способствовать решению проблемы надежности электроснабжения в условиях высокой степени износа основных производственных фондов и дефицита необходимых инвестиций для их своевременного обновления. The paper studies the role of energy security as an integral part of any successful economic development of the region. The relevance of the topic chosen due to the fact that the stable and safe operation of the energy sector is the basis for stable functioning of all branches of the national economy. It is stated that energy plays a key role in all sectors of the regional economy and the state as a whole. It is alleged that the maintenance of a stable level of energy security is an essential condition for ensuring the stability of an integrated system, which includes social, economic and environmental aspects. The stability of this system largely determines the quality of life of the population of the regions and municipalities, and at the same time is the final measure of the effectiveness of public administration, as well as the successful economic development of the territories. Mentioned adverse effect on the ecological environment and human from the energy sector, as one of the energy security threat to the region and state as a whole. It is emphasized that the state is not able to develop the entire energy sector only at the expense of budget funds, and therefore absolutely essential part of business investment aimed at the maintenance and reconstruction of the power grid industry. It is noted that the authorities sent some effort to systematize the legal framework in the field of public-private partnership (PPP). Implementation of PPP should ensure that the positive dynamics in the stabilization of energy security in the region. It is noted that these facts testify to the interest of governments in the development of this mechanism as an efficient tool for implementation of the state energy policy to ensure the long-term development of Russian regions. Proposed specific measures, implementation of which will contribute to solving the problem of power supply reliability in a high degree of wear of fixed assets and the deficit of necessary investments for their timely renovation.

States in the Mediterranean region that have already experienced the effects of these changes need to take the climate factor into account when managing water resources. Using the example of the Republic of Cyprus, specific adaptation measures were studied and evaluated on the basis of their effectiveness, sustainability in the face of climate change uncertainty and their sustainability in the environmental, socio-economic sectors, as well as potential barriers and risks associated with the implementation of adaptation. The presented review showed that many of the measures taken, which are considered to address the impact of climate change on water resources, increase the adaptive capacity of the water sector, but its overall vulnerability remains high, as water demand is still not met in certain areas and / or for certain uses during a drought.

Analysis of the material of the petrochemical industry objects due to their long operation is extremely important to assess their safety. In this paper, we analyzed the effect of long-term operation of petrochemical equipment of unalloyed and low-alloyed steel at climatic temperatures in technological environments containing hydrogen sulfide on the degradation of the structure of this equipment. We have carried out calculations of carbon diffusion to the surface during decarburization, indicating a clear possibility of diffusion fluxes of interstitial elements occurring under climatic temperatures and long exposures. The paper presents data on the structure and technological precipitation of equipment components after long-term operation (30 years or more) in oil refineries. We have carried out calculations of carbon diffusion to the surface during decarburization, indicating a clear possibility of diffusion fluxes of interstitial elements occurring under climatic temperatures and long exposures. The reason for decarburization during operation in an environment containing hydrogen sulfide, in this case, should not be attributed to hydrogen corrosion, but to an oxide layer forming due to the presence of condensate and water vapor. Анализ состояния материала объектов нефтехимической промышленности в связи с их длительной эксплуатацией крайне важен для оценки их безопасности и работоспособности. В данной работе анализируется влияние на деградацию структуры нефтехимического оборудования из нелегированных и низколегированных сталей длительной эксплуатации при климатических температурах в технологических средах, содержащих сероводород. Приводятся данные исследования структуры и технологических отложений элементов оборудования после длительной (30 и более лет) эксплуатации на предприятиях нефтепереработки. Выполнены расчеты диффузии углерода к поверхности при обезуглероживании, которые указывают на явную возможность протекания при климатических температурах и длительных выдержках диффузионных потоков элементов внедрения. Причину обезуглероживания при работе в среде, содержащей сероводород, в данном случае следует связывать не с водородной коррозией, а с образованием оксидного слоя вследствие наличия конденсата и паров воды.

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.

Актуальность выбранной темы обусловлена тем, что стабильная и безопасная работа энергетического хозяйства является основой для устойчивого функционирования всех отраслей народного хозяйства. Констатируется, что энергетика играет ключевую роль во всех секторах экономики регионов и государства в целом. Утверждается, что поддержание стабильного уровня энергетической безопасности является важным условием обеспечения устойчивости комплексной системы, которая включает в себя социальные, экономические и экологические аспекты. Устойчивость данной системы во многом определяет качество жизни населения регионов и муниципальных образований и одновременно является итоговым показателем эффективности государственного управления, а также успешного экономического развития территорий. Упоминается неблагоприятное воздействие на экологическую среду и человека со стороны энергетического сектора как одной из угроз энергетической безопасности регионов и государства в целом. Подчеркивается, что государство не в силах развивать всю энергетическую сферу только за счет бюджетных средств, а поэтому абсолютно необходимо участие бизнеса в инвестициях, направленных на поддержание и реконструкцию электросетевой отрасли. Отмечается, что органы власти направляют определенные усилия на систематизацию нормативно-правовой базы в области государственно-частного партнерства (ГЧП). Реализация механизмов ГЧП должна обеспечить положительную динамику на стабилизацию энергетической безопасности в регионах. Отмечается, что данные факты свидетельствуют о заинтересованности органов власти в развитии данного механизма как эффективного инструмента реализации государственной энергетической политики для обеспечения долгосрочного развития регионов РФ. Предлагаются конкретные мероприятия, реализация которых будет способствовать решению проблемы надежности электроснабжения в условиях высокой степени износа основных производственных фондов и дефицита необходимых инвестиций для их своевременного обновления. The paper studies the role of energy security as an integral part of any successful economic development of the region. The relevance of the topic chosen due to the fact that the stable and safe operation of the energy sector is the basis for stable functioning of all branches of the national economy. It is stated that energy plays a key role in all sectors of the regional economy and the state as a whole. It is alleged that the maintenance of a stable level of energy security is an essential condition for ensuring the stability of an integrated system, which includes social, economic and environmental aspects. The stability of this system largely determines the quality of life of the population of the regions and municipalities, and at the same time is the final measure of the effectiveness of public administration, as well as the successful economic development of the territories. Mentioned adverse effect on the ecological environment and human from the energy sector, as one of the energy security threat to the region and state as a whole. It is emphasized that the state is not able to develop the entire energy sector only at the expense of budget funds, and therefore absolutely essential part of business investment aimed at the maintenance and reconstruction of the power grid industry. It is noted that the authorities sent some effort to systematize the legal framework in the field of public-private partnership (PPP). Implementation of PPP should ensure that the positive dynamics in the stabilization of energy security in the region. It is noted that these facts testify to the interest of governments in the development of this mechanism as an efficient tool for implementation of the state energy policy to ensure the long-term development of Russian regions. Proposed specific measures, implementation of which will contribute to solving the problem of power supply reliability in a high degree of wear of fixed assets and the deficit of necessary investments for their timely renovation.

States in the Mediterranean region that have already experienced the effects of these changes need to take the climate factor into account when managing water resources. Using the example of the Republic of Cyprus, specific adaptation measures were studied and evaluated on the basis of their effectiveness, sustainability in the face of climate change uncertainty and their sustainability in the environmental, socio-economic sectors, as well as potential barriers and risks associated with the implementation of adaptation. The presented review showed that many of the measures taken, which are considered to address the impact of climate change on water resources, increase the adaptive capacity of the water sector, but its overall vulnerability remains high, as water demand is still not met in certain areas and / or for certain uses during a drought.

Analysis of the material of the petrochemical industry objects due to their long operation is extremely important to assess their safety. In this paper, we analyzed the effect of long-term operation of petrochemical equipment of unalloyed and low-alloyed steel at climatic temperatures in technological environments containing hydrogen sulfide on the degradation of the structure of this equipment. We have carried out calculations of carbon diffusion to the surface during decarburization, indicating a clear possibility of diffusion fluxes of interstitial elements occurring under climatic temperatures and long exposures. The paper presents data on the structure and technological precipitation of equipment components after long-term operation (30 years or more) in oil refineries. We have carried out calculations of carbon diffusion to the surface during decarburization, indicating a clear possibility of diffusion fluxes of interstitial elements occurring under climatic temperatures and long exposures. The reason for decarburization during operation in an environment containing hydrogen sulfide, in this case, should not be attributed to hydrogen corrosion, but to an oxide layer forming due to the presence of condensate and water vapor. Анализ состояния материала объектов нефтехимической промышленности в связи с их длительной эксплуатацией крайне важен для оценки их безопасности и работоспособности. В данной работе анализируется влияние на деградацию структуры нефтехимического оборудования из нелегированных и низколегированных сталей длительной эксплуатации при климатических температурах в технологических средах, содержащих сероводород. Приводятся данные исследования структуры и технологических отложений элементов оборудования после длительной (30 и более лет) эксплуатации на предприятиях нефтепереработки. Выполнены расчеты диффузии углерода к поверхности при обезуглероживании, которые указывают на явную возможность протекания при климатических температурах и длительных выдержках диффузионных потоков элементов внедрения. Причину обезуглероживания при работе в среде, содержащей сероводород, в данном случае следует связывать не с водородной коррозией, а с образованием оксидного слоя вследствие наличия конденсата и паров воды.
