Reid vapor pressure analyzers ABB models overview
The Reid vapor pressure analyzers RVP4500 Series consist of several models to cover various range requirements. The ranges allow the analyzers to be used not only on the final gasoline blending, but also on the various feed stocks to the gasoline blender.The RVP4550 offers a novel air saturation step that simulates the manual air saturation step of the laboratory method for the final gasoline blending operations. The RVP4540 is the version that is used to measure the vapor pressure in LPG and NGL streams.

Reid Vapor Pressure (RVP) is a vapor pressure measurement of gasoline and its feed stocks that is measured at a constant set of conditions which is used to monitor the quantity of light compounds in the gasoline. This measurement is used to reduce the amount of pollution from light compounds such as butane from escaping into the atmosphere and also to make sure there are enough light compounds to make sure car engines will start in cold temperatures.
ASTM Method D5482 (off-line mode)
- The ASTM Method D5482 was developed for this analyzer
- Allows results from process measurements to be accepted by the regulatory agencies
ASTM Method D323
- The measurement results correlate with the ASTM D323 with no correction factors or calibration required.
- Gasoline Blending
- Measuring lights in de-butanizer tower bottoms
- Shale Gas
