The article provides with information on hydrocarbon loss, as well as economic and environmental problems, and fuel energy is a necessary factor in saving resources. The analysis of losses in the current state of technological processes of transportation and storage of hydrocarbons is presented. Detailed information on the role and functions of collars and gas station and the types of petroleum products stored in them is provided. The article provides information on the physical and chemical properties of pure petroleum products. It also provides analytical information on the amount of product lost during evaporation of gasoline products. It is shown that the parameters of gasoline products change with increasing temperature. The composition of petroleum product vapors during storage is indicated in the gas station, and it is shown that the loss of products by these vapors causes environmental problems. At petrol stations, petroleum products are represented by their technological parameters and their values from the point of view of fire danger. The concentration values between the lower and upper limits of explosion hazard are indicated in the range from 0.76 to 8.4% for gasoline products, for kerosene products - from 1.4 to 7.5%. All technical parameters of AI-80 gasoline fuel are analyzed. There are analyses of the amount of product lost during evaporation when filling gasoline in cars. As a result of the analysis, with an increase in the boiling point of the fractions, the difference in the mass of the molecules also increases, the molecules become heavier. For the lightest oil products, the fractionation properties of fractionated substances are described, and the properties of the compound according to the physical parameters of pentane C5H12 are analyzed. The preservation of gasoline joints is an urgent problem and the methods currently used to eliminate them are presented. A new technology for capturing hydrocarbon vapors using a thin condenser for capturing petroleum vapors was also proposed. The advantages of the technology of absorption and separation of steam-air mixture based on the technology of absorption and separation in the process of filling and storage of petroleum products are presented for gas stations. As a result of the conducted studies, it is shown that the amount of hydrocarbons in the form of a vapor-air mixture depends on the temperature. The amount of oil product vapor released into the environment by bears is 0.09 ... It is proved that the ratio of 0.12% is based on the results obtained.
