Refinery gases

Gas analytical solution with integrated autovalidation for process quality monitoring in refineries

Measuring composition and impurities in refinery gases to optimise process efficiency and hydrogen quality.

H2S in refinery fuel gas

Refinery fuel gas is a collection of light hydrocarbon gases. To meet environmental regulations, the concentration of H2S in fuel gas is monitored before burning instead of SO2 after combustion. Typical range: 0-300ppm.

The traditional approach

  • Online gas chromatography (GC) has high consumption of carrier gases and requires frequent maintenance and calibration.

  • Lead-acetate tape analysers use consumables that require maintenance and special handling to dispose of tape that is classified a hazardous waste.

Our solution

Accurate measurements by SpectraSensors' unique Differential TDLAS Spectroscopy helps address changing fuel gas composition with automated 2-point daily validation.
