Energy Flow Model Of Oil Tank Farm And Its Energy Consumption Analysis

As a link between oil field production and consumption, oil tank farm is a huge energy using system which is composed of oil storage tank, transfer pump, heating furnace and the other energy using unit according to certain topological relationships. Energy consumption in production increases with the increase of oil tank farm reserve scale. However, for this kind of complex and dynamic energy using system, the present research only aims at main energy using equipment such as transfer pump, which is short of systematic and comprehensive. Therefore, applying mature simulation theory of process system to simulate system parameter corresponding to oil tank farm and using thermodynamic analysis method to evaluate and analyze its energy utilization have strong significance to enhance fine and overall management in energy using and excavate system energy saving potential.
