Development of energy-efficient vapor-recovery means of petroleum products to improve environmental safety gas filling stations
The increase of petroleum products demand due to the development of the global automotive industry is accompanied by the aggravation of environmental problems, which increases the potential hazard to the population. The problem of increasing environmental pollution associated with road transport is becoming increasingly important. The solution to this problem lies in developing devices of vapor recovery of petroleum products. The analysis of techniques applied for oil products vapor recovery in the operating conditions of underground storage tanks of gas filling stations allowed revealing the most promising ones. The paper presents the results of the evaluation of qualitative and quantitative characteristics of air-fuel mixture displaced from the tanks when refueling vehicles. The dependence of the of fuel vapors amount displaced when refueling vehicles on the ambient temperature is defined. The air component composition in different areas of gas filling stations is defined by means of a chromatograph. Some system meant for oil products vapor recovery out of the tanks when refueling cars at gas filling stations is developed. Application of the developed system of oil products vapor recovery at gas filling stations will allow reducing fuel losses from evaporation, using energy-efficient technologies, as well as improving the environmental safety of gas filling stations.
