Abstrakt

The flash point of liquid fuels, especially of light distillates such as gasoline or naphtha, is an important parameter for the handling of such materials. In this work, flash points and volatility characteristics (vapor pressure, boiling point) of a numbe r of shale gasoline samples with different volatilities were measured. The shale gasoline fractions were produced from Kukersite oil shale using solid heat carrier retorting technology. Several existing correlations for calculating flash points of hydrocar bons and petroleum fractions are evaluated, and the absolute average deviations were found to be between 1.1 to 20.9 °C . New, easy - to - use correlations are proposed for estimating flash points for oil shale based gasolines from volatility characteristic tha t are readily available. The correlation proposed in this work are based on the vapor pressure at 20 or 37.8 °C (100 °F ), Reid vapor pressure (37.8 °C ) or boiling point. The average absolute deviations for these correlations were 0.82 to 0.93 °C , meaning t hey are comparable to or better than existing methods developed for petroleum oils, which mostly use boiling point as the input parameter, when applied to gasoline from Kukersite oil shale.
