Why do gas stations have no choice but to generate oil vapors?
It seems obvious, but let’s think about why. Because if you know the reason, it is easy to empathize with the high incidence. If it is a very small amount, there is no need to worry. But if it’s a lot, it’s a serious problem.To help you understand, let’s first consider the evaporation of water. Hang wet laundry to dry on its own. This is because water turns into steam and blows away. Isn’t it strange? Water boils at 100 degrees and turns into steam, but it dries even if you leave the laundry unheated. As a result, water vaporized no matter what temperature it was, so it is correct that it has evaporated.
More precisely, it is called evaporation. When it becomes a gas at the boiling point, it is called vaporization, and when it becomes a gas at a lower temperature, it is called evaporation. Well, in the end it is vaporization, but…
The important thing is why? no see. When a cup is full of water, the water molecules above the water level are affected by the air above it. One absorbs heat and another receives kinetic energy by the movement of air. To put it simply, the molecules on the top surface are heated and vibrated. Then it will be easier to escape.
The same goes for gasoline. The boiling point of gasoline starts at 30 degrees, so it evaporates much more easily. Gasoline runs for tens of km in a tank truck from a distant gas station, and kinetic energy is accumulated. And the heat from the sun increases the temperature.
In Korea, tank trucks only run at dawn. However, tank trucks in Southeast Asia, which are hotter than Korea, deliver in the middle of the day. When the heated gasoline is sent to the gas station storage tank, the gasoline molecules filled with kinetic energy will join the escape procession.
In this situation where gasoline has to be moved every day using a transport vehicle, it is impossible to prevent huge oil vapors from being generated at gas stations.
