Abstract:

This article presents a methodology for calculating motor gasoline losses at filling stations due to two main factors: large tank vents and leaks through process damage. Step-by-step calculations are provided, including determining the molar mass and density of gasoline vapor, the volume of the gas space, the pumping and draining times, and estimating the leak volume through fistulas. The results show that the time to drain gasoline from a tank truck is approximately 34.2 minutes, while the leak volume through a 0.9 mm diameter fistula can reach 84 liters in 7.1 hours. The methodology is based on current regulatory documents and can be used for the design, operation, and optimization of filling stations.
