Importance
Vapor pressure is a vital physical property of volatile liquids, significantly affecting the performance of automotive and aviation gasoline. It influences vapor resistance during startup, heating, and high-temperature or high-altitude operations. In some regions, legal limits on gasoline’s maximum vapor pressure are enforced to prevent air pollution. For crude oil, vapor pressure is crucial for production, refining operations, and initial processing. Additionally, vapor pressure serves as an indirect measure of the volatilization rate of volatile petroleum solvents.
