Estimating LEL and flash

It follows then, that knowing the stoichiometry and having a vapor pressure chart, one can determine the LEL and flash point. Also if either the LEL or flash point is known, a vapor pressure chart can be used to estimate the other. [Pg.273]

The stoichiometric concentration of ethanol in air is thus 1/15.28 = 0.0654mol fraction. The LEL is 50% of this or 0.0327 mol fraction. This matches the reported value of 3.3% by volume. [Pg.273]

The partial pressure of LEL ethanol is 0.0327 atm. The temperature that produces a vapor pressure of 0.0327 atm is I l C. which is our predicted flash point. This is close to the reported 13°C. [Pg.273]

The Gooding article presents graphs that show high accuracy for these methods. [Pg.273]
