Previous issue date: 2016-12-19 / Este trabalho ? resultado de um estudo de an?lises experimentais que mediram a taxa de evapora??o, em fun??o da temperatura, de quatro combust?veis, a saber: gasolina comum, ?lcool combust?vel, Diesel S10 e gasolina GRID, realizados para seis n?veis t?rmicos diferentes, seguido de uma an?lise de custos das perdas potenciais por evapora??o, aplicada a tanques subterr?neos de postos de combust?veis. Quando esses combust?veis liberam vapores ? atmosfera podem causar danos ao meio ambiente. Em postos de servi?os, esse vapor ? liberado quando do abastecimento do ve?culo ou pelas linhas de respiro do Sistema de Abastecimento Subterr?neo de Combust?veis - SASC. Quando o posto n?o possui prote??es contra essas emiss?es fugitivas, elas atingem flora, rios, len??is fre?ticos etc. Al?m da polui??o dos recursos naturais, a perda por evapora??o atinge as finan?as do posto de combust?vel, tanto pelas multas geradas pelas contamina??es, quanto pela perda de ativo, os combust?veis. Dos combust?veis avaliados, o que apresentou a maior taxa de evapora??o foi a gasolina GRID, seguido da gasolina comum, ?lcool e diesel S10. / 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.
