Sustainable ways of oil refinery development via process integration

Oil refining is an energy-intensive production and depending on the degree of oil conversion, oil composition, the range and quality of products and other factors the reduced energy consumption by refineries is equivalent to 6– 10% of the refined oil. Reduction of energy resources in the industry can be achieved by the wide implementation of modern energy-saving technologies and the creation of highly efficient engineering complexes. Although this challenge is far from being new for the petrochemical industry, two factors appeared last time which attached special significance to energy saving and prompted the extension of the range of methods and devices used for this purpose. First, the rise in energy prices has encouraged more saving of energy to reduce total costs. Second, the rate of economic growth has significantly decreased and put new plants into operation and implementation of new processes are difficult. Therefore, more and more attention has to be shifted towards increasing the efficiency of existing facilities. Heat Integration is a key tool for energy saving achieved by heat recovery in reprocessing industries. Energy saving has an important role in achieving a sustainable future development. Heat recovery at Process and Total Site levels provide a considerable potential for energy saving. Use of excess heat can give a way to reduce the use of primary energy and contribution to global CO2 mitigation. Heat Integration is the main tool for industrial energy expertise, which provides the recommendation for decision makers during the efficient retrofit, new concept design and strategic planning.
