MiniVap On-Line RVP Analyzer

On-Line vapor pressure (RVP, TVP and vapor/liquid ratio) analysis according to all major industry standards.

  1. General Details

    MiniVap On-Line RVP Analyzer is a process monitoring system for the determination of the vapor pressure of gasoline, crude oil, LPG and NPG. Also, the vapor-liquid ratio (LVR) of gasoline can be measured. The measuring principle is identical to the MiniVap benchtop systems.

    Up to 2 different sample streams can be connected to one single analyzer. It is the only available process vapor pressure tester that fully complies to the industry relevant ASTM standards for gasoline (ASTM D6378), crude oil (D6377) and LPG (D6897).

    The unmatched accuracy makes refineries save thousands of Dollars each day!

    The On-Line RVP Analyzer’s measuring principle is based on the triple expansion method of Grabner Instruments´ worldwide approved and accepted laboratory vapor pressure tester for gasoline and crude oil: MiniVap VPS. The US-EPA declared MiniVap the official reference instrument for the USA in 1993.

    With MiniVap On-Line RVP Analyzer, the vapor pressure of gasoline (D6378 / D5191), crude oil (D6377 / D323), liquid petroleum gas (D6897 / D1267) and the vapor-liquid ratio temperature of gasoline (D5188) can be determined. With possible connection of up to 2 different sample streams, these measurements can be performed with one single instrument.
