Abstract To establish the numerical model for calculating the air loss during the period of static storage, loading, offloading of oil in tanks, the initial and final temperature during the period of emissions was estimated, and vapor pressure of oil product was considered. Based on Fick spreading law, continuity equation and distribution characteristics of oil-gas in actual tanks, it is capable of getting oil-gas concentration model.According to the logical relationship between air loss and concentration of oil-gas, actual amount of breathing loss could be get. Compared with the measured data, it is confirmed that the concentration model and the air volume measurement method are reliable, and the average error of the newly constructed model is about 38% of other models..

Key words： metrology breathing loss measurement oil tank concentration of oil-gas numerical simulation
