Energy Integration and Optimization in Oil Refineries of Iran

This paper investigates the status of four Iranian refineries in respect of energy consumption and calculates their energy consumption index and the potential for energy saving to reach the predetermined benchmarks. After initial data gathering, they have been subjected to analysis, validation and reconciliation. Then the energy complexity factor for each refinery is calculated by selecting the method for application of the best technology. Finally, an index based upon BT% and SEC has been obtained for the refineries and the levels of energy consumption for the refineries have been compared with those of refineries around the world. The method considered to determine energy consumption index is to employ the best technology index. Eventually, the potential for energy saving is obtained for each refinery.
