拱顶罐油品蒸发及油气扩散的数值模拟研究
Numerical Simulation Study on Oil Evaporation and Oil Gas Diffusion in Dome Roof Tanks
摘要
Abstract
Dome top tanks are important facilities for oil storage,and in order to reduce the evaporation loss of storage tanks,it is necessary to conduct research on their evaporation loss mechanism.Establishing a UDF for the absorption of heat flux at different times in a dome roof tank,and using FLUENT 19.0 software to simulate and analyze the effects of solar radiation intensity,oil storage height,and oil storage time on the diffusion of oil and gas inside the tank,the simulation results showed that:the gas temperature distribution inside the tank was uneven,with a vertical distribution of high and low,and the average gas temperature inside the tank decreased with the increase of oil storage height.The mass fraction of oil and gas in the tank is similar at the same oil level height,with the highest mass fraction on the oil surface.The vapor mass fraction is positively correlated with the oil storage height and storage time.The maximum pressure value of the gas inside the tank in a day first increases and then decreases,gradually increasing with the height of the liquid level.This study provides a basis for evaluating the evaporation loss of storage tanks and designing and managing oil and gas recovery systems.关键词
