What is the Reid vapour pressure of gasoline?

Reid vapor pressure (RVP) of gasoline is the vapor pressure at 100°F.

What does the Reid vapor pressure test measure?

The volatility of gasoline.


What are factors affecting the reid vapor pressure of an oil?

The amount of light components in the oil affect the reid vapor vapor pressure. In petroleum products such as gasoline, the amount of butane in the gasoline blend has a strong affect on the Reid Vapor Pressure. To reduce RVP more stripping steam can be added to the product strippers. The fractionation in the debutanizer might also need to be adjusted to affect the RVP.

What is Reid Vapor Pressure?

Under the ASTM Method D 323 (Reid vapour pressure), it is the absolute vapour pressure exerted by a liquid at 100°F. The higher this value, the more volatile the sample and the more readily it will evaporate. Unlike distillation data, vapour pressure provides a single value that reflects the combined effect of the individual vapour pressure of the different petroleum fractions in accordance with their mole ratios. It is thus possible for two wholly different products to exhibit the same vapour pressure at the same temperature - provided the cumulative pressures exerted by the fractions are the same. A narrow-cut distillate, for example, may exhibit the same vapour pressure as that of a dumbbell blend, where the effect of heavy fractions is counterbalanced by that of the lighter ones. In conjunction with other volatility data. Reid vapour pressure plays a role in the prediction of gasoline performance.


Reid vapor pressure of water?

Depends on temperature. For ASTM D323 the RVP of water is ~49.5 mmHg (torr) gauge or ~809 mmHg absolute (assuming standard pressure). FYI - ASTM D323 is measured at 100F.
