The Study on Energy Loss Distribution Law for Energy System of Oil Depot

The Grey box models of pipeline subsystem and oil depot total system have been set up in accordance with practical production process of a certain oil depot in Daqing Oilfield by applying thermodynamic analysis method of energy system. Analysis criteria of energy loss are put forward on the basis of energy using models and energy balance equations. According to operating parameters during production, energy loss distribution in each part of the system has been worked out. Then, the forming reasons of relatively large energy loss are analyzed, so that improvement direction of energy saving measures can be pointed out in order to provide theory foundation for enhancing energy using levels of the oil depot system.
