Refinery Gas Analysis

What is Refinery Gas Analysis (RGA)?

Refinery gas analysis is a commonly used gas chromatography-based test method to characterize gases produced during crude oil refining. This includes stack emission, flame, and reformate streams. Although the composition of the gases varies, they typically contain C1 to C5 paraffins, C6+ paraffins, C2-C5 olefins, and non-condensed gases. All of which can be measured using our refinery gas analyzer.

Clients in the petrochemical production and petroleum refining industry can greatly benefit from the use of our RGA system. It features high-quality materials and components such as a flame ionization detector. Furthermore, it can provide the fastest analysis results in the industry.

Separation Systems’ RGA Solution

Our refinery gas analyzers (RGA) utilize a gas chromatograph configured with three separate channels:

  1. The first one is equipped with a flame ionization detector (FID) to separate and measure the hydrocarbon species
  2. The second one is equipped with a thermal conductivity detector (TCD) to measure the non-condensed gases. These include CO, CO2, argon/oxygen, nitrogen, H2S, helium, and hydrogen.

Lastly, the thor one uses nitrogen carrier gas and TCD to measure hydrogen if greater sensitivity is required.

Quick and Effective Refinery Gas Analysis

Our refinery gas analyzer stands out from the rest. It provides solutions for petroleum refining, petrochemical production, biofuels, and more. It provides the following benefits:

  • Quality: The analyzer’s hardware is made up of the highest quality materials. This ensures durability and helps with providing effective analysis. 
  • Fast analysis: Refinery gas analysis cycle times generally take as long as 20 minutes or more. However, Separation Systems can configure ‘Fast RGA’ systems with analysis cycle times as little as  6-8 minutes.
  • Reporting software: The system features a special software to provide a comprehensive report on the analysis results from each of the individual channels. 
  • Flexibility: The RGA system can be configured to analyze gaseous and/or ‘compressed’ liquid streams. 
  • Standard methods compliance: Our RGA system is fully compliant with industry-standard test methodologies.
