Повний текст джерелаThesis 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.

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 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.
