ParaFuel Crude Oil Analyzer

ParaFuel™ Crude Oil Analyzer

ParaFuel™ Crude Oil Analyzer

Complete Crude Oil Monitoring

Whether in a refinery, midstream, or an agency enforcing regulations, measuring properties of Crude Oil quickly and accurately is critical. No matter where in the crude oil industry you are, the ParaFuel™ Analyzer will enable optimized quality, safety, and process control schemes.

Measure Critical Properties in Real-Time

With the ParaFuel™ analyzer, accurate measurement of a diverse range of crude oil products and properties is easy. Whatever the analytical need – Crude Blending, pipeline management, or validating  shipment quality – the ParaFuel™ can do the job. You can expect low costs, fast results, and minimal maintenance requirements from the process hardened ParaFuel™ online system.

A Versatile Tool for Petroleum Processes

Monitor all your key properties in a single test that takes only seconds

  • A wide range of in-process probes and cells available for any process condition or material.
  • Available in single channel, eight channel, or 20 channel versions so you can get the most measurement value from one analyzer.
  • Communication protocols of virtually any type are available.
    If you are integrating with an older system or a brand new DCS, we have the integration options for you.
  • Achieve Real-Time process control using results to adjust critical process parameters.

Realize the Benefits of Real Time Analysis

Perfect for Real-Time Control

Analysis is nondestructive, automated and takes seconds, results sent to your DCS.

  • Crude Blending in real-time to optimize usage of lower cost crudes
  • Monitor Crude Oil grades in real time to manage inventory quality
  • Pipeline Crude testing for insertion and loading quality parameters

Real Time Process Analytics

LT-NIR Process Systems provide the same high-quality measurements as lab analyzers, directly in process. Monitor changing process conditions in real time and adjust as necessary. With the capability to measure 20 points with a single analyzer, gain knowledge of the whole process. Validate quality and performance at all stages—raw materials, intermediaries and final product. Design quality into your system.
