Refinery gas analysis is a commonly used gas chromatography based test method to characterize gases produced during crude oil refining including stack emission, flame and reformate streams. Although the composition of the gases vary, 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.
Our refinery gas analyzers (RGA) utilize a gas chromatograph configured with three separate channels; one equipped with a flame ionization detector (FID) to separate and measure the hydrocarbon species, one equipped with a thermal conductivity detector (TCD) to measure the non-condensed gases (CO, CO2, argon/oxygen, nitrogen, H2S, helium and hydrogen) and one using nitrogen carrier gas and TCD to measure hydrogen if greater sensitivity is required. The RGA system can be configured to analyze gaseous and/or ‘compressed’ liquid streams.. Analysis results from each of the individual channels is combined to produce single comprehensive report using special software provided with the system.
