Does stable gasoline contain C4? What is the allowable range for the content?
Generally, the initial boiling point or vapor pressure is controlled, without C4.
The saturated vapor pressure of stable gasoline is under control; a higher content of C4 compounds results in a higher saturated vapor pressure, and there are specific criteria for this
Keep the content of C4 in the stabilized gasoline at no more than 1%
Due to the existence of vapor-liquid equilibrium, it is inevitable that a small amount of C4 will reach the bottom of the tower. The exact allowable range cannot be determined without laboratory analysis; however, this range can be ascertained by analyzing the vapor pressure of the stable vapor. By controlling the vapor pressure directly, it is possible to regulate the amount of C4
Stabilized gasoline naturally contains a small amount of C4, as C4 is a key component in stabilizing the gasoline at the bottom of the stabilization tower, and it is also crucial for determining the vapor pressure of this gasoline. Especially in cold outdoor conditions during winter, if gasoline used as fuel in gasoline engines lacks C4, it will be very difficult to start the engine and drive the vehicle； Of course, to reduce the losses that occur during gasoline storage and transportation due to high summer temperatures, it is possible to minimize the C4 content in stabilized gasoline.
