Abstract
This article analyzes methods for reducing gasoline evaporation losses in vertical cylindrical storage tanks. The main sources of evaporative losses are identified as “standing losses” and “working losses,” which occur due to daily temperature fluctuations and technological operations such as filling and emptying the tanks. The influence of key factors affecting evaporation intensity, including Reid Vapor Pressure (RVP), ambient temperature, tank volume, and structural characteristics, is examined. A comparative analysis of fixed-roof tanks, floating-roof tanks, and hermetically sealed tanks is presented. The results show that the installation of deflector discs in pressure-vacuum valves and the application of vapor condensation technologies can significantly reduce gasoline evaporation losses. The proposed approach improves both the economic efficiency of petroleum product storage and environmental safety.
