Icon Scientific introduces Vapor Pressure Analyzer

April 14, 2015 – Icon Scientific introduces Vapor Pressure Analyzer that uses laser measurement technology and has explosion proof certification for hazardous area use.

Primarily used in testing crude oil, gasoline, LNG condensate or liquefied petroleum gas, vapour pressure is the pressure exerted by vapour in equilibrium in a closed system above a liquid at a specified temperature and vapour-liquid ratio. The vapour pressure analyser utilises the piston expansion principle to measure vapour pressure in line with all the latest expansion based test methods.

Operation without the need for industrial air or expensive purge gases has led to full, explosion proof certification for Hazardous Area use.  The explosion-proof housing has an integrated, sophisticated, user-friendly 17” wipe clean glass touchscreen.  Certifications include ATEX (Europe) and IECEx (worldwide including Australia); ETL/CSA listing for use in Canada and the US (plus countries where American standards are preferred); the latest CU TR (which replaces the older GOST certification); and Japanese TIIS certification.

The unit can simultaneously measure Reid Vapour Pressure Equivalent and True Vapour pressure according to AS D6377. Precise measurement also enables the analyzer to determine vapour pressure temperature relationships and use them to predict vapour pressure over a wide temperature range. 

An additional feature is that the analyzer can simultaneously measure Gas Oil Ratio - an important environmental measurement.  The analyser can simultaneously measure TVP, RVP and GOR  (at tank storage temperature) and also output RVPE at 37.8 (100F) for product specifications. For gasoline blending control, it can measure the RVP and V/L20 simultaneously.

A cooled sample cell can return samples straight back into the process, removing the need for cooling water, external chillers and pumped sample recovery units.   

It uses Modbus 485 as standard, whilst also having Modbus over fibre optic capability for TCP/IP internet control.   In addition, OPC software enables the analyser to communicate directly with a customers’ Distributed Control System.
