JP3 vapor pressure analyzer to helps ensure low crude volatility during transport

May 20, 2015

JP3 Measurement announces the launch of the industry's first in-line, field deployable, optical vapor pressure analyzer--the Verax VPA. For the first time, operators can measure vapor pressure in condensate and crude oil in real time with no sample conditioning.

Developed specifically to measure the volatility of crude oil, NGL and condensate, the Verax VPA provides real-time measurement of vapor pressure (RVP, TVP, or VPCR) during processing or loading operations. The VPA provides operators the ability to measure the vapor pressure of crude before and during loading, thus ensuring that its volatility has been reduced to safe transportation levels. Between 2008 and 2013, the number of crude oil originated rail car loads increased from 9,500 to almost 400,000, according to Association of American Railroads (

By measuring with probes directly in the pipeline at operating pressure and temperature, the Verax VPA eliminates any concern of paraffin clogging, often associated with measuring vapor pressure. The VPA will return a measurement every 30 seconds to ensure that the product being loaded or unloaded meets vapor pressure specifications from start to finish.

In addition, the unit works on loading skids and stations, needing only 24 volts DC power to operate. The process connection is a simple process bypass, consuming zero product.

Using patented near-infrared optical spectroscopy and advanced communications, the Verax VPA provides real time data, communicates directly to your control system, and gives the user unprecedented levels of monitoring and control over the product being handled.
