Эксергетический анализ установки первичной переработки нефти
Аннотация
Излагаются вопросы термодинамического эксергетического анализа сложных химико-технологических систем(ХТС), основанного на изучении преобразования эксергии в технологических аппаратах и установках с целью рационального использования циркулирующей в ХТС эксергии. Выполнен эксергетический анализ действующей установки ЭЛОУ-АВТ на действующем нефтеперерабатывающем заводе при увеличении ее производительности, обеспечивающей необходимую степень подогрева нефти.
Кимёвий — технологик тизимлар (КТТ)да айланиб юрадиган эксергиялардан окилона фойдаланиш максадида эксергияда технологик аппарат ва цурилмаларда эксергия конверсиясини урганишга асосланган мураккаб КТТнинг термодинамик эксергик тахлил масалалари баён этилган. Ишлаётган нефтни цайта ишлаш заводида мавжуд булган ЭЛОУ АВТ цурилмасининг (эксергик тахлили) самарадорлигини ошириш билан зарур булган, нефтни керакли даражада иситишни таъминловчи эксергетик тахлили утказилган.
The questions of thermodynamic exergy analysis of complex chemical- technological systems based on the study of the conversion of exergy in technological apparatuses and installations for the rational use of exergy circulating in the CTS are set forth. An exergy analysis of the existing ELOU-AVT unit at an existing oil refinery was carried out with an increase in its productivity providing the necessary degree of oil heating.The issue of thermodynamic assessment of the effectiveness of complex chemical-technological processes and production based on exergy indicators on the example of primary oil refining processes is considered. The methods of exergy analysis of the effectiveness of both individual elements and assemblies of complex and technological installations as a whole are discussed. Structural optimization of energy technology processes is focused on the application of the methods of resolving terms of linear programming.The modern development of chemical and petrochemical technology is characterized by an increase in unit capacities and an increase in the efficiency of existing facilities. This is due to qualitatively new structural solutions related to the organization of interaction and processing of energy flows between individual subsystems of industrial production and the need to maximize the use of energy from technological flows within production. Chemical-technological processes of industrial production are in direct connection with energy flows, forming a single whole — a chemical-technological system or an energy-technological installation which is aimed at solving two problems: the production of finished products of the required quality and the reproduction of energy needed to conduct the process. From these tasks, the problem of the maximum use of the energy of technological flows within the system follows. A distinctive feature of energy technology industries is the variety of sources and potentials of generated energy. In this regard, it becomes necessary to use for analysis and synthesis of the optimal organization of energy technological processes the method of exergy analysis, which allows to correctly assess the quality and optimal distribution of available energy resources
