Icon's Vapour Pressure analyser

VpVapour Pressure Analyser

An essential measurement of fuel volatility for gasoline, crude, condensate, LNG and LPG production

Icon's Vapour Pressure analyser measures the vapour pressure held in equilibrium above a liquid, at a user-specified temperature and vapour-liquid ratio.

Precision laser performance

A breakthrough non-contact measurement for a highly accurate, highly repeatable performance

icon scientific’s proprietary laser technology enhances process control and ensures process safety across all areas of production, transportation and storage.


How Vapour Pressure works

Variable piston expansion enables vapour pressure testing to wide range of temperatures and vapour-liquid ratios

Product flows into a measuring cell, where resistance thermometers enable the cell and sample temperature to be accurately controlled. A small, defined volume of the sample is held in place by a piston, which utilises icon’s laser controlled liquid-vapour ratio measurement technology for exceptional accuracy and superior repeatability.

Once equilibrium is established, the absolute pressure inside the cell is converted into actual vapour pressure as required by the test method being emulated. This enables the vapour pressure to be measured in accordance with various test models and the most up-to-date standards.

Versatile operation

Able to perform single or multiple expansions, Vapour Pressure can test samples across a broad range of temperatures and liquid-vapour ratio - and offers a unique simultaneous four-measurement analysis for crude oil (TVP, RVP x 2, gas-oil ratio)

Excellent repeatability

Vapour Pressure uses a unique Peltier cooler and cartridge heater design, enabling the highly accurate control and measurement of cell and sample temperature for better repeatability.
