May I ask which type of gasoline requires pressurization during transportation and handling?

That pressure isn’t applied externally; rather, gasoline itself contains various components that generate pressure on their own.
Gaseous liquids or chemicals that need to remain in a liquid state under certain pressure are generally transported using pressurized tank trucks. Such as liquefied petroleum gas (LPG), liquefied natural gas (LNG), ammonia, and various volatile chemical products. In the situation you mentioned, loading gasoline and transporting it using pressure tankers may refer to specific types of gasoline, such as highly volatile gasoline or special-grade gasoline; due to their high volatility, it is necessary to transport them under certain pressure to ensure safety or maintain the quality of the gasoline. Traditional regular gasoline generally does not need to be transported under pressure, as it is in a liquid state at normal temperature and pressure, and its volatility is moderate, so it does not easily generate high vapor pressures. Therefore, a pressure of 2 kilograms may indicate that this type of gasoline has special physicochemical properties or transportation requirements. For more accurate information, you can check the shipping documents, Safety Data Sheet (MSDS), or consult the supplier to learn about the specific type of this gasoline and its transportation requirements. For safety reasons, it is necessary to follow the appropriate safety regulations and operating procedures when handling such chemicals. .
It’s not the internal pressure; it’s 2 kilograms of nitrogen added
I don’t know anything about gasoline transportation. The guess is that it serves to prevent air from getting in; during transportation, the shaking of gasoline generates static electricity, and poor conductivity together with trapped air can potentially lead to combustion. A nitrogen seal provides better protection

The situation you mentioned is called nitrogen sealing; it is a measure taken to ensure the safety of oil products during storage and operation in sealed conditions, as well as to protect their quality. This is based on the same principle as flammable and explosive materials as well as nitrogen blanketing in some chemical processing units. The saturated vapor pressure of gasoline itself does not reach such a high level.
