Numerical Simulation of Temperature Drop Process of Large Crude Oil Storage Tank
Studying the temperature drop process of large crude oil storage tanks and accurately analyz-ing the temperature distribution of stored oil products can not only provide a scientific and accurate basis for the engineering design of storage tanks,but also provide guidance and assistance for the safe opera-tion,energy conservation and consumption reduction of crude oil storage tanks.To meet the insulation requirements during the construction of storage tanks,a heat transfer model for large crude oil storage tanks is established,the effects of crude oil rheological properties,solar radiation intensity,soil tem-perature field near the tank base,and the air interlayer inside the floating tank roof on the temperature distribution of crude oil inside the tank are considered.Taking a large crude oil storage tank in the East Africa Storage Tank Project as an example,numerical simulation calculations are conducted on the whole process of 24-hour temperature drop of the oil in the storage tank under different insulation me-dia and different insulation layer thickness conditions.The calculation results show that the temperature drop of crude oil near the floating top of the tank is small,so insulation of the floating roof is not re-quired.On the premise of meeting the technological requirements of tank insulation facilities,the opti-mization of insulation layer materials and thickness is conducted based on the simulation and calculation results,which can achieve the purpose of energy conservation,consumption reduction,and reducing project investment.
