| Summary: | The introduction of low–waste and waste–free technologies is an actual development direction for oil
and gas enterprises, in particular for oil refineries. Development of methodological approaches to the
analysis and synthesis of complex energy systems in order to increase the efficiency and environmental
safety of the objects under study through the introduction of low–waste and waste–free technologies,
the implementation of technological cycles close to closed. The solution of the task is carried out in
accordance with the basic principles of the system analysis of complex objects, in stages: analysis of the
structure of the object using the decomposition–aggregation approach; determination of internal and
external links between the elements of the system; determination of the regularities of the functioning
of the object and the complex of influencing factors. A block–hierarchical structure of an oil refining
enterprise has been developed, which establishes quantitative and qualitative links between the
elements of the system at all levels of the hierarchy. A system of performance indicators is proposed, in
accordance with which an assessment is made of the current state of the object under study. The most
energy–intensive production facilities of an oil refining enterprise have been determined, their exergy
balances, have been calculated. The analysis made it possible to assess the potential for increasing
environmental and energy efficiency, the main directions for the implementation of low–waste and
waste–free technologies. Science–based directions for improving environmental safety and energy
efficiency of the object of study are determined. Several options for schemes are proposed, an
assessment of the energy and technical and economic efficiency of the integration of the proposed
solutions into the energy complex of oil refineries is carried out. The results obtained confirm the
feasibility of integrating the proposed scheme in an existing enterprise. |
