Full textThesis for granting the Degree of Candidate of Technical sciences in Specialty 05.17.08 – "Processes and equipment of chemical technology". – National Technical University "Kharkiv Polytechnic Institute". Ministry of Education and Science of Ukraine, Kharkiv, 2018. The work is focused on solving the actual scientific and applied problem of the heat transfer intensification in plate heat exchangers of welded design for special applications, namely the heat recovery of flowsheets in refineries and chemical plants. The work suggests the new approaches towards estimation of heat and hydraulic behavior inside channels of plate heat exchangers with welded sealing. The proposed approach is based on the heat and momentum transfer analogy, and is applicable for corrugated plates of square and round shape. The semi-empirical correlation determining the heat transfer in the channel of plate heat exchangers, which enables to take into account the influence of the Prandtl number, is developed. A physical-and-mathematical model of fouling deposition during the time in welded plate heat exchangers is proposed based on the "threshold" fouling model concept, which allow the thermal resistance caused by fouling deposition to be predicted in time for different velocities of the flow and temperatures of eat carriers. The possible application conditions for crude oil pre-heat train are considered and welded plate heat exchangers of two types with minimal heat transfer surface area were designed for each operation position. The modification of shell-and-plate heat exchangers was proposed, applying the plates with different cross-section area of cold and hot channels, which can be used for the conditions when the flow rates for the heat carriers differs significantly. The case study of the waste heat utilization from refinery is considered. The utilization of the waste low-grade heat for the district heating and hot tap water supply is proposed, with the design of twenty individual heat sub-stations for each household using the welded plate heat exchangers.

Full textДиссертация посвящена изучению трещиноватости пород-коллекторов и определению ее влияния на характер нефтегазоносности локальных структур месторождений Долинского нефтепромышленного района. В диссертации теоретически и экспериментально установлено, что в продуктивных горизонтах месторождений нефтепромышленного района на глубинах (2,5-3 км.) имеются эффективные открытые трещины с раскрытием порядка 1000 мкм. Уточнено структурно - тектоническое строение Долинского месторождения в результате графических построении установлено ряд тектонических нарушений. Путем анализа характеристик начальных параметров продуктивности скважин и гидропроводности пластов установлено, что зоны максимальной трещиноватости пространственно связаны из зонами развития тектонических нарушений. Соответственно скважины, которые пробурены в пределах выделенных зон- высокопроизводительные. Дебиты которых в 3 - 4 раза превышают дебиты скважин, которые пробурены за пределами выделенных зон. Установлено, что наличие порово-трещинного коллектора предонродпляет преобладающую концентрацию запасов углеводородов на участках, которые размещены вдоль тектонических нарушений и в особенности их взаимопересекаемости, зон максимального развития тектонической трещиноватости. Установлено, что высокая производительность скважин и соответственно значительная интегральная добыча нефти - следствие закономерного распределения трещиноватости пород-коллекторов и распространением порово-трещинного коллектора. На этих особенностях базируются предложения относительно удержания от строительства нагнетательных скважин в зонах повышенной трещиноватости продуктивных горизонтов и бурения сетки добывающих скважин на участках которые предопределяют превосходящую концентрацию запасов углеводородов и непосредственно прилегают к тектоническим нарушениям, а также сгибов продуктивных горизонтов в сводчатых частях складок. Полученные результаты в комплексе с анализом мероприятий по повышению нефтеизвлечения, которые проводилось на месторождениях в процессе их разработки, следует положить в основу проектов доразработки па поздней стадии эксплуатации.В диссертации проведены исследования влияния геодинамических напряжении на формирование коллекторских свойств пород-коллекторов, установлены особенности влияния трещиноватости на характер притоков флюидов в скважинах при этом зоны трещиноватости локальных структур необходимо рассматривать, как один из главных показателей дифференциации характеристик коллекторских свойств пород и соответственно их нефтегазоносности, который безусловно необходимо учи ть ван. при проведении поисково-разведочных работ.

Full textДиссертация посвящена разработке новых и усовершенствованию традиционных технологий увеличения степени извлечения и текущей добычи газа, нефти и конденсата из истощенных месторождений природных углеводородов. В работе охарактеризованы особенности и проблемы завершающей стадии разработки месторождений газа и нефти, остаточные запасы углеводородов в истощенных месторождениях и известные технологии заключительной стадии разработки месторождений природных углеводородов. Обоснованы направления научных исследований актуальной проблемы повышения газонефтеконденсатоотдачи и интенсификации добычи газа, нефти и конденсата из истощенных месторождений природных углеводородов. По результатам теоретических исследований получена аналитическая зависимость текущего пластового давления в газовом месторождении с газовым режимом разработки от характеристик призабойной зоны пласта и технологических параметров работы скважин и системы сбора газа. Предложена математическая модель процесса взаимодействия в газовом месторождении с макронеоднородными коллекторами участков пласта различной проницаемости и степени дренирования с перетоками газа между ними. Сформулирована и решена в оптимизационной постановке обратная задача теории разработки газовых месторождений, которая позволяющая оценить забалансовые запасы газа в некондиционных коллекторах. Экспериментально на моделях пласта установлены основные закономерности извлечения защемленного газа с обводненных газовых месторождений с макронеоднородными коллекторами. Предложена технология повышения газоотдачи обводненных газовых месторождений снижением в них давления путем совместного отбора газа с водой из добывающих скважин при одновременном блокировании поступления в месторождение законтурной воды нагнетанием неуглеводородного газа в приконтурные скважины. По результатам экспериментов на моделях пласта разработаны технологии извлечения сконденсированных углеводородов из истощенных газоконденсатных месторождений и остаточной высоковязкой нефти из обводненных нефтяных месторождений. На основании компьютерных экспериментов установлены закономерности процессов формирования и расформирования конусов подошовенной воды при периодической цикличной эксплуатации добывающих скважин на газовых месторождениях. Обоснован дифференциальный подход к бурению уплотняющих скважин на истощенных нефтяных месторождениях, который, в зависимости от распределения нефтенасыщенности и пластового давления на площади месторождения, предусматривает бурение в зонах концентрации невыработанных запасов нефти только добывающих или только нагнетательных скважин или одновременное бурение нагнетательных скважин в зонах пониженного пластового давления и добывающих - в зонах с повышенным пластовым давлением. На основании лабораторных экспериментов и опытно-промышленных работ обоснованы методы очистки призабойной зоны газоконденсатных скважин от сконденсированных углеводородов, воды и твердой фазы, выноса жидкости с низконапорных газовых и газоконденсатных скважин и интенсификации добычи высоковязкой нефти из нефтяных скважин. Результаты прикладных и теоретических исследований прошли опытнопромысловые испытания и внедрены на месторождениях Украины.
The thesis is devoted to the development of new and improvement of existing technologies of increasing the degree of recovery and current gas, oil and gas-condensate from the depleted fields of natural hydrocarbons. The analytical dependence of the current reservoir pressure in the gas field was proposed based on the near bottomhole zone characteristics of the reservoir and technological schedule of the wells and gas gathering system operation. The mathematical model of interaction between zones with different permeability in depleted gas field and gas migration between them was developed. The inverse problem of the theory of natural gas field development was formulated and solved, which allows to estimate outbalance gas reserves in substandard collectors. The basic regularities of the trapped gas recovery process from watered gas fields with macroheterogeneous collectors were determined. The problem of the formation and disbandment of the bottom water cone was investigated applied to the cyclic, periodic wells operation in the fields with bottom water. The methods of condensed hydrocarbons extracting from depleted gas-condensate fields and high-viscosity residual oil from flooded oil fields were substantiated. A differentiated approach to in-fill wells drilling in depleted oil fields was proposed. The methods of bottomhole zone cleaning from condensed hydrocarbons, water and solids, fluid removal from low-pressure gas and gas-condensate wells and lifting high-viscosity oil from oil wells were proved. The results of applied and theoretical studies have been pilot-scale tested and implemented in the fields of Ukraine.

Full textThesis for granting the Degree of Candidate of Technical sciences (PhD degree) in specialty 05.17.08 «Processes and equipment of chemical technology» (16 – Chemical and bioengineering) – National Technical University «Kharkiv Polytechnic Institute» of Ministry of Education and Science of Ukraine, Kharkiv, 2017. The processes of separation and especially rectification of gas and liquid mixtures are one of the most energy consuming in the industry. Under the experts estimation, up to 5% of all energy that is used by the humanity is consumed in these processes. That is why the dissertation work is devoted to the solution of ac-tual research-and-applied tasks of increase of capacity of recuperation of heat energy during the processes of rectification of wide fraction of light hydrocarbons (WFLH) and related processes. As a result of the analytical review of the publication, the classification of the methods of increase of capacity of recuperation of heat energy in chemical techno-logical processes with the purpose of decreasing of specific energy consumption intensity in production processes was carried out. The methods of internal heat in-tegration of rectification columns as with integration of the heat pump (HP) from the column and without integration of HP were considered. The works, which were concerned with the application of Pinch Analysis methods to increase the capacity of recuperation of heat energy on the plants of chemical production, were examined. The analysis of works, which were related to the increase of specific energy consumption of heat in the territorial production complexes (Total Site Integration), was carried out. In the analysis of publications, the works of pioneers in the field of Integration Processes such as Professor B. Linnhoff, Professor R. Smith, Professor J. Klemes, and the works of scientists of our country such as Professor L. L. Tovazhnyansky, Professor P. A. Kapustenko, Professor L. M. Uliev, are mentioned in particular. The analysis of published works allowed putting to the tasks of increasing the specific energy consumption of the process of heat recuperation on the rectification plants WFLH with the production of propane-pentanoic, propane-hexane, butane and isobutene fractions and finding the methods of their solution. To solve the given task, the process of heat energy recuperation in the gas-fractionation shop of the oil refinery, which consisted of two lines of rectification WFLH was studied. One of the tasks is to get propane-pentanoic, butane fractions; the other is to get pentane-hexane, butane and isobutene fractions. In addition, the installation of primary creaking enters into the territorial production complex. The simulation models of the separation of WFLH were designed with the help of the software UniSim Design.

The simulation models of the separation of WFLH were designed with the help of the software UniSim Design. The analysis of technological processes, their regulations, and data of simula-tion models permitted to record the production line table of the process under the research. Such table is the numeral factor of the technological flows that take part in the system of heat exchange of the plant. And also, the net diagram of the existing capacity technological system of the rectification plant WFLH with obtaining of propane-pentanoic and butane fractions was established. Moreover, the capacity of the processes of the recuperative heat exchange on the plant Qrec=1230 kW was determined. The data, which were obtained as the result of the analysis, allowed to construct composite curves for the rectification process for the existing heat ex-change recuperative system and determined the capacity of hot QHmin =67274 kW and cold utilities QCmin= 65982 kW, which the process of rectification consumed at that moment. The analysis of the composite curves gave the opportunity to deter-mine the minimum temperature difference between the heat transfer agents in the heat exchanging equipment of the plant Тmin = 30 С. This value is the parameter, which shows the ability to increase the capacity of recuperation of the heat energy in the process. On the basis of the theoretical analysis of the system of technological flows of the process of recuperation WFLH, with the use of Pinch Analysis methods, the optimal value of the minimum temperature difference between heat-transfer agents ΔТoptmin = 6 °С was determined, and for this value a net diagram and technological scheme of the project of reconstruction of the system of recuperative heat exchange were constructed. The main parameters of new heat exchangers were defined. As the result of the project of reconstruction, which was proposed, the ca-pacity of the recuperation of heat energy would be Qrec = 13575 kW that is, it would increase by 1102%, the capacity of hot and cold utilities would be QHmin =54914 kW, that is they would decrease by 18.37% and 18.67% accordingly. The theoretical analysis of the heat exchange system with the help of composite curves device allowed establishing limit factor for the further increase of the capacity of heat energy recuperation. The analysis of the integrated heat exchange system of the process of rectifi-cation of WFLH with the help of the big composite curve (BCC) made it possible to eliminate the limit factor with the help of creation of the method of optimum in-tegration of recompression heat pump (HP) into having been integrated process of rectification. The constructed simulation UniSim Design models of HP integration in both processes of rectification, which proved the increase of the capacity of recuperation of the heat energy in the process of rectification WFLH with obtaining of propane-pentanoic and butane fractions comparing to the existing process, by 1590 %, and the capacity of hot and cold utilities decrease by 72 % and 73 % accordingly were created. During the integration of the heat pump in the process of rectification WFLH with obtaining of pentane-hexane, butane and isobutene fractions, the ca-pacity of recuperation increases from the value 1725 kW to 21270 kW that is, by 1233 %, and the consumption of hot utilities will decrease from the value 41112 kW to 22490 kW, that is by 53 %, cold utilities will decrease from the value 42812 kW to the value 23260 kW, that is by 54%. For the further increase of the capacity of the processes of heat, energy recu-peration the analysis of the whole territorial complex of rectification plants WFLH (Total Site Integration) was conducted. Using BCC of rectification processes, for the first time the heat profile of the complex of different rectification plants WFLH was constructed, the analysis of them made it possible to determine technological flows, on which it was possible to install additional recuperative heat exchangers that helped to increase the capacity of recuperation of heat energy by 23,4 MW. In the result of integration of the plants complex the total capacity of the recuperation of the heat energy increased by 1986 %, but the capacity of hot and cold utilities increased by 51 % comparing with the utilities of processes currently. In the dissertation work, the economic analysis for each of the proposed project of the increase of capacity of recuperation of heat energy was carried out. In the dissertation work, the task of increasing the capacity of recuperation of heat in the existing two-flow heat exchange systems in the presence of utility paths was solved. The dependence of heat carries temperature and thermal loading on heat exchange equipment on additional area of heat exchange surface and intensity of heat transfer were determined. The most suitable placement of the new heat exchange surface was determined and the value of the area of the surface of heat ex-change for the minimum present value of the project reconstruction and minimum payback term were found. The method, algorithm and program of the calculation of the additional area of the surface of the heat exchange for two-flow systems of the recuperation of heat energy were created.

Full textDissertation to obtain Academic Degree of Doctor of Engineering by the specialty 05.17.08 – Processes & Equipment of Chemical Technology. – National Technical University "Kharkov Polytechnic Institute", Kharkov, 2017. The Dissertation deals with creating theoretical and methodological basis of i chemical technological processes ntensification in order to improve the current and develop new efficient technology and equipment for hydrocarbon energy carriers' production and refining. System analysis of the energy transformation processes proved that the limiting stages of chemical technological (diffusive, thermal, hydro-mechanical, mass-exchanging and chemical) processes in hydrocarbons production and refining could be hurdled with the help of object oriented activation. It has also been proved that the proposed water activation method for the diffusion process together with chemical and mechanical-chemical activation provide for considerable increase of permeability of pay section compacted reservoirs. Together with thermo-baro-chemical processing the method ensures hydro-cracking of asphalt-resin-paraffin depositions directly in the bottom-hole formation zone. This foundation was used to create technology for integrated water and thermo-baro-chemical impact on wells' pay horizons, the efficiency of which was proved by experimental and industrial implementations at oil and gas wells including also methane production from coal fields. Principally new methodology for hydro-cavitational activation of hydrocarbon- containing emulsions and suspensions was theoretically substantiated and developed. It provides for obtaining composite fuels with the assigned energy and environmental characteristics due to intensification of physical, chemical and heat-mass-exchange processes.
