Taxa de evaporação de combustíveis em função da temperatura: análise termoeconômica aplicada a postos de serviços do RN

Abstract

This work is the result of a study of experimental tests that measured the rate of evaporation, temperature, of four fuels, namely: ordinary gasoline, ethanol fuel, Diesel and gas GRID, S10 for six different heat levels, followed by a cost analysis of the potential losses for evaporation, applied to underground tanks of gas stations. When these fuels release vapors into the atmosphere can cause damage to the environment. In service stations, this vapor is released when the supply of the vehicle or the vent lines of Underground fuel supply system-SASC. When the gas station does not have protections against these fugitive emissions, they reach flora, rivers, groundwater etc. Apart from the problem of pollution of natural resources, the loss by evaporation reaches the finances of the gas station, both by the fines generated by the contamination, and the loss of active, fuel. Of fuels evaluated presented the highest evaporation rate was the gas GRID, followed by ordinary gasoline, alcohol and diesel S10.
