Study on Temperature Distribution and Variation of Oil Vapor in Fixed Roof Oil Tank

A heat-transfer model for fixed roof oil tank is set up. Combined with actual field data, deductions for temperature distribution of oil tank are made theoretically. By means of linear fitting and gray correlation analyses, theoretical data deducted are showed a high accuracy. Factors influencing variation of temperature field are analyzed and conclusions provide references for further research on evaporation loss and rational selection of surface coating materials of oil tank.
