MINIVAP ON-LINE is a process monitoring analyzer 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 worldwide used laboratory instruments MINIVAP and therefore the MINIVAP ON-LINE produces equivalent results.
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).
Features
- On-line Compliance Monitoring for Vapor Pressure of Gasoline, LPG and Crude Oil and Vapor/Liquid-Ratio Temperature of Gasoline (V/L=20)
- One Single Instrument for up to 2 Sample Streams
- Multiple Point Measurements at Different Nominal Pressures
- Automatic Calibration & Offset Correction
- Temperature Controlled Sample Conditioning System
- 7 Minutes Cycle Time
Vapour Pressure Tester Standards
- ASTM D6378 – Vapor Pressure of Gasoline (VP4)
- ASTM D6377 – Vapor Pressure of Crude Oil
- ASTM D6897 – Latest standard for Vapor Pressure of LPG
- ASTM D5191
- ASTM D5188 – V/L-Ratio: T (V/L = 20)
- ASTM D4953
- ASTM D1267
- ASTM D323
Applications
The 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.
With MINIVAP ON-LINE, 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.
