The volatility of gasoline
Thread Content
We all know that gasoline is highly volatile, and under normal conditions it is stored in sealed containers. But after it evaporates, is its density greater than or less than that of air? We are currently building a gas station, and we have some doubts regarding the explosion-proof zone for gasoline engines! Could someone please explain in detail, or tell me in which book I might have found relevant information?
I’m also puzzled by this issue; gasoline does tend to evaporate easily, with a saturated vapor pressure of around 0.6 bar at room temperature. If these volatile gases are present in higher concentrations than in the air, it can be very dangerous. But in reality, gasoline isn’t that dangerous; at least its level of danger is much lower than that of liquefied gas. Gasoline is grade A B, T3. Last edited by dreamxy2008 on 2007-12-24 17:45.]
I consulted in detail with the electrical engineering staff at my company, and they said that gasoline vapor is heavier than air; in ordinary gas stations, the explosion-proof radius is 15 meters. A graduate student in chemical engineering also said that it is heavier than air
