Reid vapor pressure (RVP) is a common measure of the volatility of gasoline and other petroleum products. [1] It is defined as the absolute vapor pressure exerted by the vapor of the liquid and any dissolved gases/moisture at 37.8 °C (100 °F) as determined by the test method ASTM-D-323, which was first developed in 1930 [2] and has been revised several times (the latest version is ASTM D323 ...
This is illustrated in the vapor pressure chart (see right) that shows graphs of the vapor pressures versus temperatures for a variety of liquids. [7] At the normal boiling point of a liquid, the vapor pressure is equal to the standard atmospheric pressure defined as 1 atmosphere, [ 1 ] 760 Torr, 101.325 kPa, or 14.69595 psi.

Propane is the primary fuel for hot-air balloons. It is used in semiconductor manufacture to deposit silicon carbide. Propane is commonly used in theme parks and in movie production as an inexpensive, high-energy fuel for explosions and other special effects. Propane is used as a propellant, relying on the expansion of the gas to fire the ...
Gasoline should ideally be stored in an airtight container (to prevent oxidation or water vapor mixing in with the gas) that can withstand the vapor pressure of the gasoline without venting (to prevent the loss of the more volatile fractions) at a stable cool temperature (to reduce the excess pressure from liquid expansion and to reduce the ...
Vapor recovery towers are also used in the oil and gas industry to provide flash gas recovery at near atmospheric pressure without the chance of oxygen ingress at the top of the storage tanks. The ability to create the vapor flash inside the tower often reduces storage tank emissions to less than six tons per year, exempting the tank battery ...
The vapor pressure of a liquid, which varies with its temperature, is a measure of how much the vapor of the liquid tends to concentrate in the surrounding atmosphere as the liquid evaporates. [30] Vapor pressure is a major determinant of the flash point and flame point, with higher vapor pressures leading to lower flash points and higher ...
